The correct technology for caulking a log house with jute. Log caulking: methods - traditional and modern, technology of work, subtleties. Ways to caulk the walls of a house or bath

Built of timber, laid, the roof is covered, and the windows are inserted - it's time to insulate the frame. Cracks can be caulked traditionally - with moss, modern material - jute or tow. How to do it correctly and what to prefer after all - read the article and watch the video.

How to choose the right material for insulation. Which is the best fit

It is almost impossible to answer unequivocally, the more correct it is to caulk a wooden bath. Each material has pros and cons, so you need to familiarize yourself with their characteristics, and only then make a final decision.

Moss... You can buy at a hardware store or type it yourself in the forest. Warming with its help was practiced by our grandfathers, and their experience can certainly be trusted. True, now this material is far from a favorite, because there are new ones that are more convenient to use. Nevertheless, the advantages of moss include:

• environmental friendliness;
• medicinal properties;
• profitability;
• resistance to decay;
• resistance to temperature extremes.

Of the minuses, it is necessary to highlight:

• exposure to moisture;
• fragility;
• high fire hazard;
• fragility when dry;
• laboriousness of the warming process.

Tow. It can be made from hemp, jute or flax and is sold in rolls and square blocks. The first option is more convenient, because individual strips need to be pulled out of the blocks, twisted and placed in the slot. Among the advantages of the material:

• naturalness;
• low cost.

Perhaps this is where the visible advantages of tow end. Minuses:

• difficulties in use. If over time you decide to remove the tow from the seams, you will suffer;
• attractive to mice and moths.

Advice. Tow is a kind of alternative to moss, which many experts advise to give preference to if you choose only between these two options.

Felt. It can be natural or with the addition of artificial fibers. The first is preferable because it is less fire hazardous (it burns worse). Felt advantages:

• environmental friendliness;
• ease of use.

• exposure to moisture and decay;
• high price;
• high risk of moths. In addition, often the felt becomes the object of encroachments by mice and birds, which pick it out from the seams.

Linen and flax fiber... Made from flax waste. Batting is a material with the addition of artificial fibers. It is more convenient in laying, since it is produced in the form of ribbons. Flax fiber is similar to tow, so working with it takes patience. The materials do not absorb moisture and are resistant to decay. You can distinguish one from the other by color: natural flax fiber is darker than flax.

Jute. This is one of the most popular options among modern owners who build and then insulate the bath with their own hands. It is made from the wood of the linden family. Characteristics - feast for the eyes:

• high strength;
• resistance to moisture and decay;
• good thermal insulation;
• environmental friendliness;
• ease of use - sold in the form of rolled strips.

Among the shortcomings, it is worth noting that jute can stick together under conditions of excessive pressure loads. True, you can try to avoid this if you choose insulation with the maximum density.

Attention! Jute and jute felt are not the same thing. The second material has the same disadvantages as any other fiber felt.

Subtleties of the caulking process

The advantages of a caulked bath are obvious: it requires less fuel, and it takes less time to warm up the premises. Therefore, despite the fact that the work is painstaking and time-consuming, it is better not to neglect it.

One of the main measures for warming a bath from a log house is caulking (caulking). Caulking is a clogging of gaps between the crowns of a log house with environmentally friendly insulation materials. In this article, we talk about how to make a caulking of a log house yourself and what materials and tools will be required for this.

Purpose of caulking a log house

After all the rims of the bathhouse from the log house are laid, inserted and the roof is closed, it is necessary to proceed to the process. The log house has been insulated for a long time, and this process has practically not changed to this day. The only thing that has changed is the materials and tools for caulking (we will talk about them a little later).

Caulking a blockhouse is necessary for the following reasons:

• For a well-insulated, it will take less time to warm up the steam room and other rooms
• The log house tends to dry out, as a result of which gaps are formed in the construction of the bath, which will need to be hammered
• If heat comes out of the bath, condensation will form outside the log house, which will entail rotting of the log house
• Heating a well-insulated bath requires less fuel (coal, gas, wood or even electricity)

As you can see, log caulking is a very serious and at the same time useful exercise.

When do you need to caulk a log house?

As we know, it takes at least one year to shrink a log building. Based on this, there is a lot of disagreement about the timing of the caulking.

The first caulking of a log house must be carried out immediately after laying all the crowns and overlapping the roof.

The second caulking of the log house is carried out after the bath has partially settled down (about a year later). Despite the fact that during the first caulking all the gaps will be tightly clogged, a year later there will be a place for another bath warming in the inter-crown gaps.

Well, the last caulking of the log house should be carried out at the time when the bath is completely seated, no later than 5 years later.

We draw your attention to the fact that do-it-yourself caulking of a log house must be carried out both from the outside of the bath, and from the inside. Another important point: during high-quality caulking, the bath can rise by about 7-10 cm, so it is better not to fix it to the roof, so that it does not deform during this time.

Materials for caulking a log house

Today, you can use moss, tow, special sealant, jute and flax for caulking a log house with your own hands. Let's take a quick look at the benefits of each material.

Moss

Previously, the log house was caulked with moss. This material for caulking is still used by some builders, but most of the experts prefer more modern materials.

The advantages of moss are that it is 100% environmentally friendly material that has antimicrobial properties and at the same time has a high durability.

The disadvantage of caulking a log house with moss is the high cost of this insulation.

Caulking moss should not be too dry, but at the same time, it should not be too wet.

Tow is also often used for caulking a log house, but this material is not recommended. First, the caulking of a tow log is a very laborious process. Secondly, the tow absorbs moisture, so after a few seasons it can start to rot, thereby damaging the crown of the log house. Thirdly, it is very difficult to pick out rotted tow from the cracks between the wedges, especially since the repeated caulking is not a very pleasant process. And fourthly, tow is a treat for moths.

Jute is an environmentally friendly material of plant origin. It is often used for caulking a log house with your own hands, because this material has the following advantages:

• The material has high strength
• Jute practically does not absorb water, which means it does not rot
• Jute has good thermal insulation properties

We draw your attention to the fact that often in hardware stores instead of jute they offer an analogue - jute felt. We do not recommend using jute felt for caulking a log house, because this material has a share of flax, and this significantly reduces the strength and increases the hygroscopic properties of the material.

The caulking of a log house with jute is carried out during the construction of a structure from a log house. The material is placed on top of the crowns and fixed with a construction stapler.

Flax is also used for log caulking. This material consists of compacted flax dust, which is made with long belts. Flax, like jute, has high strength and heat-insulating properties.

Sealant

Special sealants for log caulking are also gaining popularity. They are most often used together with jute. There are different types of sealants depending on the width of the cracks. We draw your attention to the fact that it is advisable to use the sealant together with jute or flax, this will make the thermal insulation of the bath more effective.

To date, the following set of tools is used for do-it-yourself caulking of a log house:

• Type-setting caulking
• Curve caulking (requires skill at work, but more effective)
• Road builder (used in conjunction with caulking)
• Split caulk (narrower, in some places it is more convenient to work with it)
• Mallet (used to drive caulk in a crevice)

It is recommended to use soft caulks (for example, made of wood), because they will not damage the surface of the log house. The only problem is that soft caulking is more difficult to use, but after a few warming, you will definitely adapt to this tool.

Diy caulking technology

The technology of caulking with your own hands is quite complicated, although you cannot say this from the outside. As we said earlier, when caulking a log house, the structure becomes 7-10 cm higher, so you need to caulk evenly and correctly.

You should be aware that no finishing measures should be taken before caulking the log house, because they will be damaged immediately when the structure is being lifted.

Correct caulking of a log house implies warming the inter-crown space in tiers (from lower to upper). First, caulk the lowest joint (between the first and second crown). This must be done along the perimeter, starting from one corner and ending with it. As soon as the tier is insulated, you need to move to the overlying crown.

We draw your attention to the fact that it is extremely forbidden to carry out isolated caulking (for example, only one wall), because log structure can be noticeably skewed.

It should be noted that experienced builders can level a skewed log house using only caulking.

When caulking a log house, it is necessary to carefully hammer in the insulation at the corners, because these nodes need it most of all (due to the presence of locks and complex grooves).

There are two ways to caulk a log house with your own hands: "stretching" and "in a set". The first method is used if the gaps between the crowns are small, respectively, the second is intended for wide slots. Let's take a closer look at each of the methods.

For caulking a log house "in a stretch" you will need a strand of insulating material for the length of the entire gap. First, it is necessary to tamp one side of the strand into the gap, then bend the other side (as shown in the picture) and carefully hammer in with a split or inlaid caulk.

This method of caulking a log house with your own hands requires much more insulation material, but it insulates a bathhouse from a log house with better quality. Caulking technology is different: a strand is prepared with a thickness of at least 15 mm. Next, the strands must be cast into loops and alternately hammer each loop into the gap (so that the strand goes across the gap, as shown in the picture). It is necessary to hammer in a strand using a split caulk, knocking the material from above, and then from below. After the strand is completely clogged in the cracks, it is recommended to make the final compaction with a road builder.

Caulking a log is a painstaking process that requires patience and great effort. Everything matters here: the tool, the quality of the material, the sequence of work. Without the appropriate experience, not everyone succeeds in driving a log house correctly, therefore, first you need to familiarize yourself with the technology, study the methods of caulking, and choose the right insulation between the joints.

Caulking rules

The caulking of a log house is performed in two stages - immediately after erection and after a while, when shrinkage occurs. Primary (or rough) caulking can be carried out in two ways: with the installation of insulation in the process of assembling the walls or a one-time execution of work on completion of construction.

1 way

The bottom row of logs are laid on the base.

Then the insulation is spread from above so that the ends of the material hang evenly on both sides. Next, the second crown is laid, and again a layer of insulation. This is repeated to the very top of the log house. After all the work on the construction of the log house has been completed and the roof has been installed, the protruding ends of the seal are hammered into the gaps between the beams using caulkers.

2 way

Caulking begins after the installation of the roofing system on the log house. Insulation (best of all, tape) is applied to the seam of the lower row and with the help of a tool is pushed into the gaps between the logs along the entire length, leaving hanging edges 5-7 cm wide.Then these edges are folded up, a roller is formed from them and hammered into the seam. Repeat the procedure in the next row and so on to the top of the structure.

The second stage of caulking is performed after the log shrinkage - after 1-2 years. The selected insulation is applied to the gaps between the crowns and tightly hammered inside. You should always start work from the bottom row, and be sure to do it around the perimeter of the log house.

You cannot caulk one wall first, then the second, and so on. In addition, each row is caulked both from the outside and from the inside to avoid distortions of the structure. The insulation raises the blockhouse by 5-10 cm, and its uneven distribution contributes to the vertical deflection of the walls. In some cases, the blockhouse is caulked for the third time - 5-6 years after construction. During this time, the wood shrinks completely, and new gaps are formed.

There are two methods of caulking - "in a set" and "in a stretch". The first is used to eliminate wide gaps between logs, the second is usually used for primary caulking, when the gaps are still narrow.

To work, you need tools - a set of caulkers, a road builder and a mallet. As a rule, metal caulkers are used, although many craftsmen independently make them from hard wood.

Name Description What it is used for

	A flat metal or wooden spatula. Blade width 100 mm, thickness 5-6 mm	The main tool for sealing gaps between rims
	Flat chisel with a blade width of 50-60 mm and a thickness of up to 5 mm	It is used for sealing joints in corners and rounded sections of a log house
	Triangular caulk with a longitudinal groove along the blade. Width - 170 mm, thickness 8-15 mm	Tool for the formation of even rollers from twisted strands of sealant
	Thick and narrow wedge up to 35 mm wide	Expands narrow gaps for easier filling with insulation
	Wooden hammer	Used for stuffing the seal with wooden caulks

The caulking blades should not be sharp, otherwise they will cut it when they clog the material. Pay special attention to the surface of the blades: if it is rough, the fibers of the insulation will cling and pull back out of the seams.

Caulking materials

The following materials are used as mezhventsovy heaters:

• red and white moss;
• tow;
• felt;
• jute;
• flax

Primary stretching caulking

The whole process is divided into two stages - the laying of insulation between the logs during the construction of a log house and the caulking itself. Insulation is laid after the installation of each crown. If moss is used, it should be slightly damp.

They take a large bunch of moss and lay it with fibers across the log so that the ends of the fibers hang on both sides by 5-7 cm. The next bunch lies close to each other.

The fibers must be evenly distributed over the surface, forming a layer of uniform thickness. The wood should not show through the moss, so make the insulation layer thicker. It is better to put too much than not to report, because a thin layer will not be able to effectively protect the seams from blowing.

If tape insulation is used, the installation is much easier and faster: the tape is rolled along the crown and fixed with staples of a construction stapler. When the tape ends, a new section is laid with an overlap of 5 cm so that there are no gaps at the joints. After the entire row around the perimeter is covered with insulation, the second crown is installed.

So, the log house has been erected, the roof has been installed, the walls can be caulked.

The procedure for caulking and sealing cracks after shrinkage of a log house

It is more convenient if the insulation is tape, then it turns out to form a roller from it much faster. When twisting the material, it must be slightly stretched along the seam, which contributes to greater compaction and even distribution of the insulation. Sometimes the thickness of the roller turns out to be insufficient to fill the gap, then they take additional strands and wrap them in the hanging ends of the material. The thickened roller is then driven into the gap.

If during the construction process the insulation was not laid between the logs, caulking is performed as described above, only more material is needed. It must be applied to the seams with fibers across. The longitudinal arrangement of the fibers will not provide the required density, the material will not be able to firmly anchor and will constantly crawl out of the grooves. When choosing a tape seal, make sure that the width of the tape is several centimeters wider than the thickness of the log. Edges that are too short are difficult to tuck and therefore the caulking quality will be poor.

If the gaps between the crowns are very wide, apply caulking "in a set". For these purposes, tow, hemp ropes or jute cords are used. Long strands are formed from tow, which are wound into a ball. Finished cords or ropes are also rolled up into balls for convenience.

They start from the edge of the lower crown:

• clearing the gap by removing chipped chips and debris;
• unwind a small amount of the cord, fold it in the form of loops and push it with a caulk into the gap;
• seal the hinges first at the top of the gap, then at the bottom;
• impose another strand on top, now without loops, and align with the road builder.

Further along the seam, the strands are laid in one layer until the next gap. The denser the voids are clogged, the better the insulation is. Try not to leave hanging fibers: firstly, they spoil the appearance of the wall, and secondly, birds can pull the seal away. Having finished caulking the first row, they move on to the second, and everyone repeats in the same way.

For decorativeness of the log house, you can hammer a jute cord along the entire length of the seams.

Caulking corners

The corners are caulked separately, after the work on the walls is completed. It is also more convenient to use tape insulation here.

Since at the corners the seams between the logs are semicircular in shape, you will need a curved caulk.

Step 1. The ribbon is positioned vertically. Take it by the edge, apply it to the fillet seam and press inward with a caulk. They step back a little and again drive the material into the gap.

Step 2. As soon as the insulation is slightly fixed, they begin to tuck the protruding edges and hammer them deeper into the cracks.

Step 3. After filling and leveling the top seam, proceed to the second. The material must be constantly straightened, and stretched a little so that it lays down more evenly.

This is how the entire corner is sequentially compacted. The seams should not protrude more than 5 mm, otherwise the look will be sloppy.

Caulking a log house with sealants

The caulking of a log house is gaining popularity with special sealants that are easy to apply, give the seams a very aesthetic look and reliably protect against blowing. If the blockhouse is made of rounded logs or glued beams, and jute is laid as a heater between the crowns, only sealant and a bundle of foamed polyethylene can be used. Sealing of the seams is carried out no earlier than the shrinkage of the log house.

Step 1. The joints between the logs are cleaned of dust and clogged debris, wiped dry with a rag.

Step 2. A primer-primer is applied along the perimeter of the seams with a brush or spray. If work is carried out in winter, the primer should be chosen on a rubber basis, in the summer - on a water basis.

Step 3... After the primer has dried, a rope of foamed polyethylene is inserted into the seams, the diameter of which is selected according to the width of the gap.

Step 4. Apply sealant. The composition is used in tubes, which is applied with an assembly gun, in buckets and in the form of a tape. The last option is very easy to use: on one side of the tape, remove the protective film, apply it to the seam, press it by hand and roll it in with a roller.

Step 5. After sealing all the joints between the joints, the outer layer of the film is removed so that the sealant hardens. At the end, the joints are covered with a colorless varnish or a tinting compound is applied, depending on the color of the sealant.

When applying the compound with a spatula or from a tube, the sealant should be smoothed out and the excess should be removed with a damp cloth.

If the logs were harvested by hand, more uneven gaps are formed during shrinkage. Here, one sealant and a polyethylene cord will not be enough. In such cases, caulking is carried out in the traditional way, after which the seams are closed with a sealant. After such processing, there is no need for subsequent caulking.

How to caulk the bath correctly: with moss, flax fiber, tow, felt

Caulking any wooden bath must be performed in two stages: after the completion of construction and after a year of shrinkage. For work, use the same insulation that is laid between the links during construction. Traditionally, baths are used for caulking: moss, felt, tow, hemp. How to properly caulk a bath with your own hands, what tools are needed and the subtleties of the work, readers will learn by studying the article to the end.

Features of caulking baths with various materials

When assembling the bath box, a heater is laid between each log or bar. But wood shrinks regardless of the drying chamber material or natural moisture. When shrinking, a space appears between the logs, so it is necessary to dig the bath for the first time in order to seal the seam and the second time to eliminate the formed cracks.

Caulking a bathhouse is easier with special tools: caulking and a rubber mallet or mallet. If there is no caulk, then you can use a regular chisel.

What material is better for caulking a bath?

For the caulking of the steam room, natural insulation is used: moss, hemp, tow, felt. All materials are available, but each must first be prepared in its own way.

Preparing moss for caulking

Warming the seams with moss is a traditional method used by our grandfathers. Moss can be collected on your own or purchased ready-made in a hardware store.

The price of moss is from 250 rubles, so it is cheaper to collect in the forest. The collected moss is laid out under a canopy and left to dry for 1–2 weeks. It is necessary to stir the moss every 2-3 days so that it does not rot. Using damp moss will lead to mold growth and damage to the wood. But it is necessary to monitor drying, as overdried moss will be fragile and difficult to work with.

Pros of moss:

• Profitability (you can dial for free in the forest).
• Natural, which means that environmental friendliness is not violated.

The material has more cons:

• It becomes brittle when dry.
• It is difficult to caulk a bath.
• It is afraid of moisture and mold.
• Short-lived.
• Burns well.

Choosing moss to caulk the log house is only necessary as an economy. From the point of view of practicality and durability, it is better to pay attention to something else.

Preparing caulking felt

Felt is a natural material based on wool. But modern felt can be made up of fumigated fibers. Moreover, the composition is: 60% wool and 40% artificial fiber, 70% artificial fiber and 30% wool. For a bath, choose a completely natural felt or felt with a high wool content. The fact is that natural material does not burn, but simply smolders. Artificial felt is fire hazardous.

Before work, the felt must be treated with a formalin solution, it will not allow the moths to dissolve in the wool. After spraying, the felt is hung in the sun and dried thoroughly.

The main advantages of felt are:

• Naturalness.
• Caulking a log house is easy.

• Natural material is afraid of moisture and rots.
• Mice and birds love to use felt to build their nests, and gouge material out of cracks in a log house.
• The high price of natural insulation.

Preparing tow for caulking a bath

It is not necessary to cook the tow especially before work. But moths and other insects like to settle in natural material, so the tow is impregnated with any protective compound, for example, formalin.

The main advantages of using tow:

• Low price.
• Natural material.
• Ease of operation.

• Afraid of moisture.
• Over time, it may start to rot.
• Mice settle in insulation.

Tow is an alternative to moss, since the price of the material starts from 70 rubles.

Jute and flax fiber for caulking a bath

Modern insulation options: jute and flax fiber can also be used to caulk a log house. But despite the manufacturer's assurances about the naturalness of the heaters, most of them contain artificial additives. They make jute and flax fibers durable, but their environmental friendliness is reduced.

Natural jute is made from the bast of the linden family. Jute has high strength, durability and moisture resistance. Water, getting on the material, does not linger on the jute fibers, but quickly disappears.

Flax fiber is made from flax waste. The material has performed well on construction sites. Does not rot and does not absorb moisture. But there are pitfalls, sellers offer the buyer flax wool instead of flax fiber. The materials are similar in composition, but the batting has 40% artificial fiber. You can distinguish one from the other by color, linen is light, and the fibers of natural insulation are darker.

Available in the form of a tape, cord. To caulk a bathhouse, tape jute or flax fiber is used.

It is necessary to caulk the log house of your bath with insulation that meets your requirements and capabilities.

Caulking the bath is necessary in two stages:

• immediately after mounting the box;
• after shrinkage of the bath.

It is difficult to caulk a log house from a profiled bar again, since the lock will not allow the work to be carried out efficiently. Therefore, it is better to take a material with a profile in a chamber drying or glued one. So, shrinkage will be minimal and you will not have to caulk again. All other types: logs, simple beams, cylinders need to be caulked again. It is necessary to work with special tools, as shown in the video:

Tools for the job

To caulk a log house, various types of caulking are used:

• typesetting;
• curve;
• broken;

A mallet (muskel) is also needed. The tool is used to hit the caulk during work. The mallet can be replaced with a regular rubber mallet. We need a road builder, the tool helps to level the seam after punching with caulkers.

What subtleties you need to know when caulking a bath

Caulking the walls of the bath is necessary from the bottom to the top along the entire perimeter. Moreover, the work is performed first by prokonopovat one row from the inside and outside, then the second, etc. The fact is that when caulking the bath rises by 5-15 cm. If you do not work consistently, the structure will warp. Caulking the bottom groove around the entire perimeter, outside and inside, then the second, the bath structure will rise smoothly and evenly.

It is necessary to take care of the chimney before caulking the log house. The pipe is released at the joints with the ceiling and roof or removed for a while so as not to damage it.

You can caulk a bath in two ways:

• in a set;
• stretching.

Let's consider each in more detail.

Sauna caulking set

Caulking into the set is necessary when sealing large cracks and grooves. The selected material is twisted into a bundle of 15–20 mm and, for convenience, is wound into a small ball. The tourniquet is placed in the gap and hammered with caulk and mallet, as in the photo.

First from above, then from below. Align everything with a road builder.

Bath caulking, stretching

The insulation does not need to be twisted into a bundle. It is simply shoved into the gap between the links, and then punched with a mallet. Work is carried out until the insulation ceases to fit between the logs of the bathhouse.

It is necessary to caulk the blockhouse slowly, carefully sealing each gap. Places where it is difficult to get with a tool are simply foamed with polyurethane foam.

We answered the question of how to properly caulk a bath using various methods. After the bathhouse has finished caulking, it must be sanded and covered with protective compounds. We will talk about this next time.

What is caulk? In fact, this is the process of compacting a log house with fibrous materials - moss, tow and others; at the same time, a heat-insulating material can be used as a mezhventsovy insulation - flax-jute fiber, polyurethane foam, for example. But it is not so easy to caulk correctly - you will learn about all the intricacies and features of this process from this article. So, how to caulk a log house - with moss, tow, tape and sealants.

• 3 Video selection of caulk examples
• 4 What tools are needed for caulking

Correct work technology

As soon as the blockhouse is laid, it is still impossible to caulk it - after all, there is shrinkage ahead. You can understand, of course, the desire of those building the bath to make money, why they propose to bury everything right there, but this should be done only after at least six months.

So, as soon as the frame has shrunk, you can begin to caulk it - from the bottom up, from the very bottom crown. This should be done like this: one seam is caulked, strictly along the perimeter of the entire log house - outside, then inside. It is impossible to caulk each wall separately - otherwise the frame will warp over time. The same applies to the separate caulking of the outer and inner sides - because of this, a dangerous vertical deflection of the walls can easily occur.

Caulking is a thorough and heavy business. At the same time, the master is obliged to constantly monitor the log house so that there are no distortions of the walls. And it's bad if, after caulking, the whole blockhouse has risen to a whole crown - this will invariably lead to the falling of the logs from the dowels or locks, and therefore it is better not to allow this.

What material should you give preference to?

So, here are the most common materials for caulking a log bath from a log house:

Moss - like the good old days

Moss is an environmentally friendly material that has medicinal properties. It resists temperature extremes and drying well, absorbs moisture, but does not rot. And most importantly, it has antimicrobial and tonic properties, and at the same time it serves for a long time.

This caulking material has been used since ancient times. Today it cannot be called the best, but many bath owners use only it during construction.

So, when laying, you can only use highly moistened moss - then after the shrinkage of the log house, it will turn into a homogeneous dense mass that will fill all cavities and cracks. Therefore, you will not have to caulk the bath anymore. However, experienced builders advise against attaching special importance to the historical experience of its use - such a finish is still quite expensive.

Oakum - not everything is so smooth

Oak caulking is the most difficult. When the log shrinks, it will gradually gain moisture and eventually rot, turning into dust. And then you will have to clean out this insulation, re-caulk everything and tightly fill the empty cavities - and this will take a lot of time and effort.

Sealants - modern technologies

Sealants for a log bath are much more expensive than tow, but they also have their undeniable advantages. Sealants as caulking means are suitable if the log house is cylindrical, or well cut from an ordinary log, and the groove in it is semicircular. And if there is jute linen in it between the logs. In this case, you can really do with one sealant. But, if the blockhouse was made using a chainsaw, and the groove in it is triangular - here it is already necessary to fill the void, i.e. caulk for real.

If you use a sealant with tow, then everything should happen according to the following scheme: the bath is caulked with tow twice, and after its complete shrinkage, the seams are sealed. And in order to save sealant, it is advisable to lay a cord from insulation in the grooves.

Moreover, for seams of different widths - different types of sealant. But the seams are light and neat. And the risk of subsequent caulking is gone.

Caulking with tape insulation

One of the simplest caulking methods is tape caulking. It does not need to be cut into strips, which makes the whole process much easier. And you need to do it like this:

• Step 1. First, you need to go to one of the ends of the log house, put the end of the tape on the ground, and, while unwinding it, gradually move to the other end. You do not need to cut the tape - it is only important that it does not twist and go in a strip. And most importantly, the tape should not be pulled, it should go slightly relaxed.

• Step 2. Returning to the beginning of the tape, you need to lift it at the end and start sticking it between the rims right from the end - the tool that was selected depending on the available gaps. As soon as it has already been passed to the end, you need to leave a margin of 10-20 cm - and only then can the tape be cut, and only with well-sharpened scissors.
• Step 3. At this stage, you can already caulk the tape. But only a little - otherwise it will go in folds. Moreover, it is necessary to caulk it not in one stage, but in several - until the tape disappears in the logs all, and the stock that was left initially also disappears. As for the process itself, the tape should be pushed as if diagonally.
• Step 4. Now you need to repeat everything - between the same crowns. Oddly enough, two or three ribbons will still easily enter there, depending on their density. Those. the caulking of the insulation itself takes at least four times than it was originally used when laying it - and this is only when caulking outside, while according to all the rules, the same must be done inside.

So, if the padding of the insulation has become dense, like wood, the caulking has gone well. By the way, masters advise taking at least 10 mm jute - and the thicker it is, the better.

What tools are needed for caulking

As for the caulking tool, in ancient times it looked like this:

But today a Chinese instrument is considered a quite worthy alternative, which is not expensive and is quite acceptable in quality.

By the way, if you use a solid tool for caulking, then chips and dents cannot be avoided - after all, it will slide off. Soft caulk is more difficult to use, but you can make it right on the spot, with your own hands. Wooden caulkers with curved edges are also being made today, for which it is quite easy to penetrate into the depth of the seam, but you need skill to use them.

In general, everything is within the power of a Russian person!

Bath caulking: technology and material selection

A log bath is a tradition that has not lost its relevance even after several hundred years. The tree has the highest level of thermal insulation among building materials, while the weight of the structure from a log house does not go beyond the permissible limit. The only conditional drawback of this technology is the presence of gaps between the laid logs.

When laying and adjusting the logs between the individual elements, there will inevitably be horizontal through cavities around the entire perimeter of the bath and before its operation, they must be caulked.

To find out how to properly caulk a bath, you need to deal with all the intricacies of this case. The caulking process itself does not contain any difficulties, however, there are several special points that must be taken into account.

This article will describe step-by-step instructions and the main points on the topic - "how to dig a bath with your own hands." In addition to describing the technology, it will also provide detailed information about how the bath is caulked, since in this case the correct choice of material plays a decisive role in the success of the whole process.

Selection of material

Forest moss is the most traditional material that our great-great-grandfathers used for caulking a log house. It is the most environmentally friendly material of all the analogues used, since it is of natural origin, collected by hand and does not undergo chemical treatment. It has bioactive properties - it does not start moths and molds.

Moss is especially appreciated for its antiseptic properties - it does not rot even when exposed to high humidity. At the same time, moss caulk is not only not subject to decay, but also protects the surrounding areas from damage, which is especially important for warming a bath.

Also, the use of moss as a material for caulking can significantly save on the purchase of material, since it can be collected in a nearby forest with your own hands. Even if there is no such possibility, its price in stores is quite democratic. Natural moss is the most rational solution to the question, what is the best way to caulk a bath?

The most common material for caulking a log house in view of its cost, but at the same time flax has the lowest quality characteristics. Before caulking a bath with flax, it should be borne in mind that there are practically no natural antiseptics in its composition - in this connection, putrefactive bacteria, which moist wood contains in excess, will quickly destroy the formed seam, after which the nearby areas will undergo degradation.

It quickly collapses under the influence of high humidity - its service life is from 1 to 3 years, after which the seam begins to crumble. It is loved by insects - moths, beetles; in a raw state, mold and fungus grow quickly enough. Without chemical treatment for the next season of operation, you can find a large number of insect larvae in it.

Note!
Some disadvantages of this material can be leveled by chemical impregnation, but this will negatively affect the atmosphere of the bath.

Of all the analogues used, flax can be called the most undesirable solution to the question: how to bury the bath?

Recently, the opinion of experts on the question, what is the best way to caulk a bathhouse? - is increasingly leaning in favor of jute fiber, which has recently appeared on the domestic market.

And it makes sense - natural jute is a durable material that contains a large amount of natural lingine, which makes it water-repellent. Also, jute is much less damaged by insects than flax.

Note!
Not to be confused with jute felt, which contains a certain proportion of flax, and, accordingly, all its negative qualities are present.
It is quite simple to distinguish them from each other - 100% jute is gray.

Cauliflower

In this process, there is practically nothing difficult - the main thing is to choose the right material for sealing joints. You will need a mallet (wooden hammer) and a set of caulkers. There are two technologies for caulking seams - stretching and in a set.

Stretching

• The insulation is pushed into the cavity by the fibers across, this is done either by hand or by caulking, depending on the width of the cavity. The material is hammered inside until about 4 - 5 cm of the edge of the insulation remains outside;
• Then, a roller of the appropriate diameter is made from the insulation, which is wrapped in the remaining edge, after which it is driven into the cavity by means of a caulking chisel;

In the set

• For this method, the insulation must be twisted into strands like a rope, the diameter of which is selected based on the size of the cavity between the frame;
• The finished strands are pushed into the gap with a caulking chisel - first the upper part is pushed, and then the lower one. A road builder is used to level the seam;

• During the caulking of the slots, the blockhouse rises a little, and therefore, it is necessary to hammer each slot along the entire perimeter and only then proceed to the next level, otherwise the bathhouse may "skew";
  
• If there is already a stove and a chimney in the bath, the pipe must be freed so that the structure that has risen due to caulking does not damage the masonry.
  To do this, it is enough to free up the space around the bath pipe by a few centimeters;

In the modern world, the meaning of the expression - my home is my fortress - takes on slightly different shades and is not limited only by the strength of the walls and the reliability of the castle. Increasingly, for the sake of increasing productivity and reducing the cost of material, manufacturers go to dubious schemes, adding various fillers to their construction products that release harmful substances during their decomposition.

This factor, together with the unfavorable environmental situation of the present world, makes its negative contribution, and can pose a real danger to human health.

To protect yourself and your loved ones, as well as to exclude the possibility of harmful effects, it is necessary to use proven and reliable materials that will help in the construction of your home and various outbuildings. Wood is not only an environmentally friendly product of nature, but its use will contribute to the long-term presence of any building in the list of fashionable and modern objects. The reason for this factor is that, despite the centuries-old experience of using wood, this material is a classic, and has long earned its place of honor, which can not be influenced by alternative opinions or fashion trends.

In addition to the environmental and external component, one of the main advantages of wood is its thermal conductivity. Houses made of this material are distinguished by the warmth of the premises and internal comfort. But in order to achieve such indicators, it is necessary to carry out a certain type of work, especially this must be done when the construction of a log house is carried out with the help of logs, since cracks and various holes are a constant companion of such walls.

Despite the fact that most experts try to eliminate this issue in the process of building a log house, it still remains relevant for a long time. The reason for this phenomenon is the fact that the insulation layer, laid between the elements of the tree, in the process of shrinking the house, loses its properties and initial advantages. For this reason, it is necessary to additionally caulk the entire building. It is better to carry out this process in 3 stages, which fit into the following time frames:
immediately after construction;
1-2 years after its completion;
4-6 years after the construction of the house.

The need for multiple actions is the tendency of wood to change its physical parameters under the influence of external influences. A tree can change its configuration not only due to pressure during shrinkage, but also due to changes in moisture content, leading to the formation of cracks.

Among the many materials that can be used in these matters, tow is the most commonly used and has a sufficient number of advantages. Therefore, the question is: How to properly caulk a log house with tow? - quite often found in people who dream of their own wooden housing.

To successfully solve this issue and do everything efficiently and reliably, it is necessary to take into account several rules leading to the achievement of the desired result.
You need to caulk around the entire perimeter, starting from the lower levels. Strengthening the process in one direction can lead to a shift in the log house and an aggravation of the situation.
It is best to caulk before finishing the building, as this process can slightly raise the overall level of the building. This technique will allow for a more rational use of the finishing material, and will eliminate the danger of the need to rework such work.
After insulating the outer perimeter of the building, it is imperative to go to the inner side, which will strengthen the overall positive picture.

These moments in most cases are the main guarantee of a quality result and a solution to the question: How to properly caulk a log house with tow.

In addition to the general rules, it is worth familiarizing yourself with the technology of insulation with the help of tow. Caulking with this material can be done in 2 ways - in a stretch and in a set.

In the first case, a strand is made from tow, which is applied to the problem area. The strand is hammered into the slot using a special tool called a caulk. Chisel-caulk, as this product can also be called, really has the shape of a chisel with a distinctive feature in the form of a wide and flat end. The tow should be clogged as tightly and deeply as possible, without the possibility of self-extraction. The edges of the insulation should protrude from the wall at a distance of 5-6 cm, since they will serve as a connecting link for the next formation, the edges of which will need to be intertwined and driven into the gap.

Insulation in a set is used in cases where the dimensions of the gaps are large enough, and the use of a strand does not lead to a positive result, as a result of which it is impractical. In this case, the tow is divided into separate strands, from which a roller is subsequently formed. This roller is hammered into the slot, and it is necessary to start this process from its upper part, and send the lower part to the depth of the slot last. Thanks to this technique, a seal of tow will form on the surface of the tree, which will be difficult to remove, and will also act on it mechanically.

Putting a log house from a log or a bar is by no means the whole task. It is also necessary to properly dig this log house: to close up the gaps between the crowns and the cracks that form when the wood shrinks. This is done so that the log house loses heat as little as possible. The quality of assembly of a log house is determined by how the crowns were laid. It is important not only to cut out the bowls and grooves correctly - between two rows of logs or beams, it is imperative to lay an inter-crown insulation.

Insulation is laid at the stage of assembling a log house

What it will be - moss, tow or jute - your business, but such a layer must be present. When folding a log house, you need to lay insulation in two layers:

• on the lower crown so that the edges of the insulation protrude 3-5 cm beyond the edges of the bowl, the width of the insulation, in general, is taken 5-10 cm more than the width of the bowl;
• insulation is also placed in the bowl of the upper crown, its edges protrude beyond the bowl by 3-5 cm.

Please note that when using moss or tow, you do not need to “tap” the material. When tapped with a hammer or the butt of an ax, the moss fibers break, and dents form on the wood, which are directed across the fibers. Such damage can lead, in the future, to the development of foci of decay. It is enough to simply compact the fibers with your palm, leveling and probing the layer, if large foreign objects come across (cones or sticks are often found in the moss) - just remove them.

Laying moss when assembling a log house

When using tape insulation, you can fix it with a construction stapler - damage to the wood from the staples is minimal, and the material is held securely. It is advisable to lay the "insulated" crowns together, so that the ball is able to take the log from both ends and lower it so as not to move the insulation.

How to caulk a bathhouse

All caulking materials can be divided into two main categories: natural (tow, hemp, moss, jute, etc.) and industrial sealants. Sealants apply faster and are easier to work with. Usually, to reduce the consumption of sealant, a cord is placed in the gap between the crowns, and only then, a sealant is applied on top of it, which, in a wet state, is leveled with a special spatula.

With caulking, it does not fit to have a scalpel-blade on hand. The working part of the tool is made of hardened carbon steel

Synthetic sealants have several disadvantages:

• some of them do not tolerate the effects of ultraviolet radiation - when irradiated, they lose their properties, crumble and are blown out by the winds. The problem is solved by strengthening the planks that will close the seams from ultraviolet radiation;
• some of the sealants for log cabins, when dried, form a monolith, which, when the wood expands / contracts (depending on weather conditions), interferes with the process and contributes to the destruction of adjacent wood fibers. For this reason, it makes sense to use flexible sealants.

EUROTEX elastic joint sealant for wood

The video shows how to use Eurotex sealant.

As shown in the video above, you can use a regular tablespoon as a tool to level and remove excess sealant.

If you decide to use one of the sealants, carefully read the instructions and the description, make sure that it is compatible with the type of wood from which the log house was erected, can be used in your region (temperature regime) and has the necessary qualities.

The use of sealant is justified in the case when it is used to seal the caulked gaps: after double caulking of the log house with tow, moss or jute, the complete shrinkage of the log house is expected and the acquisition of operational dimensions, after which a cord is laid in the seams, and then the sealant is applied.

Natural materials for caulking also have their advantages and disadvantages, in addition, each of them needs some preparation.

The most proven material for caulking a bath is moss. It has been used for centuries. Many other materials have appeared today, but they have not surpassed the characteristics of moss. It is more convenient to work with new (especially tape materials). This is undeniable, but the qualities of moss have remained unattainable for them. The main among them is the ability to resist bacteria and high resistance to decay.

Not aesthetically pleasing, but practical

The moss is first dried, then moistened again before use. This restores elasticity to the stems. The soaked moss is laid out in an even layer so that its ends hang down on both sides of the log / bar. After harvesting the log house, too long stalks of moss are cut, everything else is tucked in and tucked into the cracks of the log house - the primary caulking of the log house is made. After it, after six months and after a year and a half, there are repeated caulking.

Jute is increasingly used in the construction of wooden baths and houses. And not just jute fibers, but roll material. Jute fiber has good characteristics: it has good heat-insulating properties, due to the large amount of lignin - a natural resin that serves as a binding element - it is practically not subject to decay and has low hygroscopicity. Even at high humidity, the jute remains dry to the touch.

Jute heaters can be of several types:

Tow is a waste that is formed during the primary processing of natural fibers. For caulking log cabins, tow made of jute, hemp and flax is used. The characteristics of the material and its quality depend on the raw material, the degree of purification of the fibers and their length. Building tow is pressed into square blocks. For use when caulking a log house, a strip of material is pulled out of the common block, twisted into a bundle and placed in a seam. More convenient to use is combed tow, which is sold in rolls.

Bath tow

It is inconvenient to work with such material: it is difficult to achieve a uniform layer when used as a mezhventsovy heater, and for caulking a log, tow has excessive rigidity, which makes it almost impossible to achieve a dense filling of the seam, the first time, and you have to periodically repeat caulking. If the choice is between moss and jute tow, then we can definitely say that moss is better for a bath - it has the ability to inhibit the development of putrefactive bacteria and fungi.

When to caulk the bath

The log house is assembled, when is it possible to caulk a fresh log house for the first time? If the blockhouse was going to moss or tow, then the remnants of material of different lengths stick out between the crowns. In this case, you can produce the primary caulking immediately: cut off too long fibers, tuck them inward and tuck into the seams. You do not need to be zealous in this. These are preliminary works, the purpose of which is to remove fibers. But this must be done following the rules of caulking. If the blockhouse is assembled on a tape insulation, nothing needs to be done.

Bath after primary caulking

The first "serious" caulking is carried out about six months after the collection of the log house. During this time, the logs / beams will lose most of the excess moisture, new cracks will appear, crowns and corners will basically "sit" in place. At this time, the first caulking is carried out. After this process, doors / windows can be installed.

The second caulk will be needed about a year after the first. A year and a half has passed since the construction of the log house, and the log house is well established. Now all seams and cracks are checked, all flaws are eliminated. Depending on the material and the quality of the work, it may be necessary, after another five years, to re-drill the seams. But there were cases (usually this is the result of the work of the "shabashniki") when the correction of caulking errors is carried out for several years in a row. Most often, such a need arises if the log house was built without an inter-crown insulation.

How much tow do you need for a bath

Any natural material for caulking is compressed many times during installation and a large amount of it can fit into the frame, even with good insulation between the crowns. No one will be able to say exactly how much tow is needed for the bath: it also depends on what material the frame is assembled from and how the grooves in the logs are cut. As a rule, more material is used for manual cutting of grooves. Also, a flaked log requires more material than a rounded log. Less is required for a log house from a bar, but even here the amount of tow or moss that will go to seal the cracks depends on the accuracy of the geometry of the bar and the depth / number of cracks that appeared during shrinkage.

Caulking rules

Caulking a log house is not very difficult, but long and dreary. Everything needs to be done thoroughly and slowly, so it takes a lot of time - it took 10 days to caulk a small 5 * 4 bath (it worked one hour for 7-8).

The main thing is not to overdo it in the efforts made when hammering in the insulation, which can lead to the fact that the frame will rise by 15 cm or more.

Log caulking rules:

• You need to start with the lower crown, moving along the entire perimeter, first from the outside of the building, then dig in the same crown from the inside. And only after that, start processing the next crown.
• When caulking, pay special attention to the corners - there are often the most significant gaps.
• With the initial caulking, you first need to pick up the hanging material, bend it down and tuck it into the slot. In this case, you need to use the tool as needed. This operation is performed on a section about a meter long, then proceed to the next section.
• In the same area, use a caulk and a wooden mallet (sometimes a hammer is used, but the mallet does not beat off the hands so well) to compact the material. You need to beat on the caulk until the material begins to spring. Then move on to the next section.
• After compaction, a gap formed. A piece of insulation is again placed in it. If this is tow, you need to roll a tourniquet of the required thickness out of it or tear off a piece of the required length from the tape. This piece is also hammered with caulk and mallet until a springy effect appears. Repeat this operation until the gap is completely filled and proceed to the next section.

As with every business, caulking requires certain skills. Since there is more than one such procedure, as a result, you will have skills. As you gain experience, you will notice the flaws that you made at the beginning of the activity - here you will have a chance to eliminate them. Actually, it is not the gods who burn the pots, but it is possible to dig a log house with more or less high quality even in the absence of experience.
