How to work with mounting foam - video demonstration of the process. Rules and sequence of installation foam work with professional mounting foam

Almost every person at least once enjoyed the mounting foam - a modern tool for sealing, repair, installation of windows and doors, sealing slots and joints. Use the mounting foam is quite simple. For this there is a special pistol, but sometimes for a small repair in the house you can do without it. But even simple work must be done correctly to achieve high quality.

Features

A huge range of mounting foam in specialized outlets makes thinking when choosing the required material. Each of us wants to choose a high-quality and inexpensive composition. Currently, specialized outlets offer for buyers two varieties of this material: household and professional. Consider the features of each.

Household

The main distinguishing features of the household assembly foam are concluded in the volume of the cylinder. Manufacturers produce this material in small cylinders (about 800 ml). The configuration of the cylinder includes a small tubule with a small cross section. In the cylinders of the household mounting foam, the level of pressure is low, it is necessary in order to significantly reduce the consumption of the material when the repair work is performed. To perform them with the help of household mounting foam, you can use a special pistol. The valve of the cylinder is designed to fix the tube and the assembly pistol.

Professional

To install doors, windows, plumbers use a professional type of mounting foam. Manufacturers produce such material in cylinders with a capacity of more than 1.5 liters. The sealant is in the cylinder under great pressure. Perform work with professional sealant is recommended using a special pistol. In order for the use of the material is most convenient, the cylinder is additionally equipped with fastener for durable fixation inside the gun. A large number of sealant in the cylinder is designed for extensive work.

Sealants of these varieties have similar specifications.When choosing the required material, it is necessary to take into account, for what purposes it will be needed. In addition, the scope of work is also important.

A distinctive feature of the composition is the possibility of re-applying.

Operating Rules

To perform high-quality repair or installation work with the help of sealant, you need to know several rules for applying material.

• The use of a special mounting gun guarantees a better result of the work performed.
• It is necessary to use a professional sealant option that has a useful property: a sufficiently low secondary extension.
• It is recommended to perform installation and repair work on the warm season: it will speed up the process of frosting foam and will retain all its technical qualities.
• When performing work, you need to use personal protective equipment.

• The sealant is recommended to use minor cracks of about 8 cm wide. If the width of the gaps exceeds this indicator, it is advisable to use other materials (brick, wood, plastic).
• To close cracks and cracks of a width of less than 1 cm, more economical and practical to use putty.
• In the process of operation, the balloon with the mounting foam must be kept the bottom up.
• Filling the gap sealant needs one third of the depth.
• After the sealant freezes, it is necessary to remove excess mounting foam with a special knife.

• After completing all the work, it is necessary to cover the frozen foam layer with special means to protect against the effects of sunlight.
• To perform work on the ceiling you need to use a special mounting foam: such a cylinder with sealant can be used in any position.
• To make deep slots or cracks, you need to use special extension adapters.
• In the process of operation, the foam cylinder needs to shake and clean the nozzle of the mounting gun from excessive sealant.

How to apply?

Before you start working with this sealant, you need to explore all the subtleties of its use. Otherwise, the quality of work will suffer, the consumption of sealant will increase significantly, which will lead to additional financial costs. First you need to choose a suitable mounting foam. The choice of material depends on the scope of work.

If large-scale work on the installation of doors, windows or plumbers is planned or a large amount of repair work, it is better to stop their choice on a professional mounting foam. The cost of materials of this kind is significantly higher, but the result of the work performed will pleasantly please.

Small renovation in the room (for example, sealing cracks) implies the purchase of household sealant.

Application of sealant without mounting gun on the surface can be carried out in several ways.

• To perform small repair work, you can do without a pistol. The cylinder valve is installed a special tube of small size. Next proceed to the beginning of the repair work.
• Professional foam can be applied using a tube, but this method will lead to large material consumption and excess financial costs.
• If it is not possible to use a mounting gun when working with a professional sealant, you can use two tubes of different diameters. To do this, a large diameter tube is fixed on a bottle with professional foam, then the second (smaller size) is attached to this tube, carefully fixed. This method will significantly reduce material consumption and reduce financial costs.

After you have determined with the method of applying foam, it is necessary to prepare the surface. In some cases, the surface of the sealant can become a false. From how carefully the surface will be prepared, the quality of seaming is depends. The surface is thoroughly cleaned from dust, dirt. Special attention should be paid to the slits that need to be used. Sometimes the surface is required to degrease.

Large cracks are pre-filled with foam either another suitable material. Only after that they can fill them with foam. This will significantly reduce the consumption of foam, will increase the quality of thermal insulation. Before starting work, the surface must be moistened. For these purposes, a simple pulverizer is perfect.

Now you can proceed to sealing. For proper execution of works, the foam should be room temperature. Before starting the process, the cylinder is thoroughly shaken. Only after that the tube is fixed on the cylinder or a gun. Now you can apply the composition.

If you decide to use foam without a special pistol, you need to take into account the shortcomings of such a process.

• Due to the high pressure in the cylinder, the foam consumption increases significantly (sometimes two, three times).
• The design of the valve of some cylinders does not provide for the use of the tube.

Execution of work on sealing with a gun significantly saves time. Make the surface of the mounting foam with a gun is absolutely not difficult.

It is enough to learn to dose the outlet of the foam. In this way, you can glue any items, not forgetting about the preparation of the surface. Then begin to apply sealant. It is important to remember that the vertical slot is needed to fill the vertical slot below, smoothly moving up.

After completion, it is necessary to carefully clean the gun from the foam using a special flushing fluid. It must be pouring into the tool. If in the process of work a small amount of sealant hit the hands, it should be removed using a solvent. Surplus foam with contaminated seats should be removed in the process of operation with a sponge moistened in a solvent. If the sealant managed to frost, it will have to remove it with a manual way.

Expired foam can not work. Writing the canoe carefully. It is impossible to bring it to the fire. If the shelf life of the mounting foam came out, the material loses its properties.

When choosing a mounting foam you need to remember that the cylinder can only be used once. Therefore, before buying, it should be carefully calculated the required volume. If there were doubts about this occasion, it is better to consult with a specialist.

Take a note of several useful tips.

• Before starting work, you should prepare a pulvelizer to spray the water to the surface before applying the foam, the knife will be needed to cut the excess material.
• In the process of performing the work, you will need a sponge or a soft cloth moistened in acetone or solvent.
• The correct dosage of sealant will significantly reduce the consumption of material.

• Remove excess sealant from the surface more convenient after four hours after applying, after complete pouring, this process will complicate significantly.
• Be sure to use personal protective equipment (respirator, glasses, gloves).
• It is necessary to air the room during operation.
• After completing all the work, it is necessary to treat the frozen foam with a special means to protect against sunlight. Make it you need to darkening foam.
• It is strictly forbidden to use a balloon next to open fire.

Mounting foam is one of the most difficult materials: if she fell on cloth, skin, or other surfaces, clean them quite difficult. But it's worth trying.

As you already know, the mounting foam is not intended for sealing holes of less than 1 cm - such slots are better filling with silicone sealants.

If a person is gaining a request "Mounting foam without a gun to how to use" in the search engine, then, most likely, he never held a bottle of foam in his hands. Accordingly, this person had no opportunity to read the instruction that was applied to the balloon. Well, fillings this gap in the knowledge of beginners and do a detailed instruction on the topic "How to use the mounting foam without a gun."

No superconditions will need - everything is extremely clear, simple and understandable.

Instrupture

- The site should be clean from dust, dirt and various kinds of contaminants.

All that can fall off - delete. Dust is cleaned. She is the main enemy for adhesion foam and surface.

- Immediately before applying the foam, the area must be mixed with water. We advise not to neglect this item and adhesion will be simply great.

- If we are talking about the installation of windows or doors, they need to be consolidated so that the foam does not deform the design. The struts must be installed in advance, but not after the fading - the mounting foam is afraid of vibration, until it hardens.

Installation foam has unique properties. Without a gun, use it or with it - in any case, you will receive an excellent result if the manufacturer did not bring in quality. But sometimes it happens that the user made a few or even one error itself, so that it will not complain their hands on their curves, but on a foam brand. Read everything written below and try to remember - these rules, tips and recommendations will be useful to you:

Instead of imprisonment

Installation foam without a gun or with it - the main thing is that the rules of use are fully respected. Then the result will be wonderful. In the extreme case, not knowing how to use and not remembering our recommendations and tips, carefully read the instructions on the cylinder - there is also everything is written.

If there is a need to fill the hole, seam or slot, the mounting foam is most often used. This material is used in the draft finish, installation of door frames, double-glazed, repair of balconies, construction of various buildings (for sealing).

Mounting foam types There are several - for different conditions and tasks.

The remedy is sold in cylinders of different volumes (from 300 ml to 1 l).

The approximate composition (may be partially different, depending on the manufacturer and type):

1. Preduits (polyols, isocionate) - the basis of foam. When contacting air, this component enters the polymerization process, expanding and foaming.
2. Propellente (crucible gas, mixture of butane and propane). Pows out the composition of the balloon when pressed.
3. Additives. Additional components that improve adhesion adjust the degree of foaming are necessary to change the operating temperature.

Specifications

Technical characteristics of mounting foam:

• Expansion. Indicates the volume that takes the mixture in 2 stages: leaving the cylinder and frozen. The greater the extension, the more denser the gap (seam, hole) will be swam. The average indicators are 10-60% for household compounds, and 180-300% for professional compositions.
• Adhesion. Indicates the chain of the composition with the surface inside the bouncer space. The higher the viscosity - the less foam will crawl. Actually, if you need to bounce holes on the vertical surface (on the wall) or on the ceiling (where the foam can be flushed to frozen). In numbers, a normal parameter is considered to be 0.4-0.48 MPa.
• Volume in capacity and output volume. Common parameters: 300 ml (there are about 30 liters of frozen foam), 500 ml (they will give about 40 liters of foam), 750 ml (they will give up to 50 liters of foam) and 1000 ml (80-100 l). The volume of frozen foam is reduced approximately, under normal conditions (room temperature).
• Temperature at which you can use foam.

These characteristics are indicated on the cylinder.

Purpose and scope

Mounting foam use in construction at stages:

• Black finish.
• Installation of door boxes, balcony and window frames.
• Communication gaskets (for sealing between pipes of water supply, sewer pipes, ventkanalov, gas pipeline and wall so that there is no vibration).

Its purpose is the sealing of holes, cavities, seams and joints between the design elements, if their width exceeds 2-3 cm. Previously, cement and pass used for such tasks, but this method is more long and complex.

Pros and cons of the use of foam as a sealing material

These nuances can be attributed to the advantages of applications:

1. Simple use (work with mounting foam does not require special experience or knowledge).
2. High rate of applying and solidification (a 300-500 ml cylinder can be completely released in 5-10 minutes, it will freeze in 3-12 hours, depending on air humidity and temperature).
3. The ability to apply with materials of any type, including metal, plastic and polymer surfaces.
4. A durable clutch with surfaces (after the frozen, it will be difficult to exhaust the foam, but if necessary it can be cut or washed with solvent).
5. Resistance to moisture (layer of frozen foam does not rot, does not mold).
6. The presence of compounds with different characteristics (for different temperatures, with different degrees of open fire).

Of the main minuses - susceptibility to ultraviolet. Under the sun beams, the foam dries over time, but it is usually used in the stage of the draft finish, and they are not left in appearance - either close up with plaster, or covered with panels (plastic, for example).

Types of mounting foam

All formulations can be divided by:

• The number of components.
• Method of application.
• Temperature.
• The degree of flammability.

By the number of components

There are compounds:

• One-component. Sold in cylinders under pressure, do not require additional components: the composition can be applied immediately by spraying it from the tank.
• Two-component. Sold in 2 separate containers. The contents of containers must be mixed in certain proportions, and the resulting mixture is used using special devices.

In building stores, most products are one-component compositions. Two-component are usually used only for industrial purposes, with large amounts of work and, if necessary, to obtain the highest possible composition characteristics.

According to the method of application

There are compounds:

1. Professional. Foam is sprayed from the cylinder, which is inserted into the construction gun. A more convenient option than spraying with a tube allows you to quickly work with a large volume (for example - gate the slots between the plates).
2. Semi-professional (domestic). A plastic tube is put on the cylinder, which will pass the mixture. Suitable for small volumes (for example - to boil the gap with the insulation of the balcony).

Plastic tubes-nozzles are sold complete with small volumes. They can be applied several times (if work is carried out in several steps, if several cylinders are used), for which it is necessary to blow the tube after use (so that the foam does not froze inside).

Pistols for mounting foam are sold separately. The minimum cost is about 300 rubles, the average - 500-800. The device is reusable, at the end of work should be washed with a special cleaner (composition on acetone solution). Even if the foam freezes inside the nozzle - it can be washed off by a cleaner or clean the mechanical path.

At a temperature in which you can use foam

The temperature conditions distinguish such types of compositions:

• Summer: Designed for use at + 5º ... + 35º.
• Winter: Designed for use at -18º ... + 35º.
• Universal: Apply at -10º ... + 35º.

The temperature of the surfaces to which foam is applied, and not the air temperature indoors. Therefore, when working in frosts (for example, if the balcony is glazed in winter, or the seams in the building under construction under construction without heating or without windows) must be heated not to the room, but the surface.

Also, the surface temperature affects the volume of mounting foam: the colder, the smaller the finished solution will be at the output.

By graceland

Actually, if the work is carried out in the room with the possibility of fire (for example, in the bath).

Product classes:

• B1: refractory.
• B2: self-fighting.
• B3: flammable.

1. Macroflex (Makroflex, Finland).
2. BISON INTERNATIONAL (Netherlands).
3. Soudal (Belgium).
4. Tytan, Hauser (Poland).
5. Bau Master, Domos (Estonia).

Rules for applying a mounting foam

Foam use, observing such rules:

• The width of the slit or holes should be in the range of 2-10 cm. Narrow cracks (up to 2 cm) is better close to putty or sealant. Wider slots are better close to brick, wood or foam, and the remaining looseness is to marry.
• When working in a cold time, a foam cylinder will need to heat: omit into the container with warm water (up to 30-40º approximately).
• Cut the excess only after 25-30 minutes after applying the foam when it completely freezes. You can do it with a building knife.
• The balloon must be kept upside down so that the gas pushed the foam. If you keep the cylinder down, gas from the tank will be released, and the foam will remain.
• After removing the lid and attachment to the gun (or to the tube), the cylinder must be shaken.
• The cylinder with the "household" foam is used entirely for 1 approach - an open container cannot be stored for a long time, it hardens.
• The slot can not be marked by more than 50%, because when expanding its volume increases.

Sophisticated nuances

In order not to cut a large amount of foam and reworked the design, consider:

1. If a hole of 3-4 cm wide and more, foam is applied in a few steps: first 1 layer, after it is frozen - the following.
2. Current foam holes are better not to fill. On the one hand, they are recommended to cover with something tightly (for example - by the board), and remove the "cover" only 30 minutes after the gates when the composition freezes.
3. When installing door and window boxes, they must be fixed with dowels and struts. If this is not done, the expanding composition can skew the box, and it will have to be installed again.

Stages of work

Step-by-step foam is used as:

• The surface is inspired by small sera, if there is.
• The surface is degreased (acetone).
• The surface is moisturized (sprinkled with water with a brush or sprayer). Foam faster and better harden if the surface (or air) is wet.
• If the room is cold, the balloon is placed in warm water.
• The balloon opens, inserted into the gun (or the tube is put on it) and shakes.
• The end of the tube is inserted into the gap, and the foam is fed portion, 5-10 cm of the slit length, moving up-up.
• After full frost (in 25-30 minutes), the protruding pieces are cut off with a construction knife.

Security measures when working with mounting foam

Mounting foam is a chemical composition located in a pressure tank. Therefore, it is necessary to work with it, following the safety rules:

1. It is impossible to drop or heat the cylinder.
2. It is impossible to use a balloon near the hot surfaces or open fire.
3. Work is carried out in gloves (if the foam falls on the skin, it will be difficult to consider it).
4. Under hand you need to keep a sponge and rag - to consider the composition if it falls on the "unnecessary" place.

Removal of foam when hitting "unnecessary" surfaces

The mounting foam is seized with the surface quickly, so if it fell somewhere, except for the desired slit - it will be difficult to consider it hard.

Methods of cleaning different surfaces:

• Leather. If the composition does not frozen - it is removed with a sponge, and the residues are washed with acetone or solvent. If frozen - cut and rubbed off with a scrub.
• The cloth. The not frozen composition is collected by any solid subject (the board is suitable). Frozen pieces are cut off, and small residues are washed off by a solvent. In both cases, the fabric may remain a difficult spot.
• Plastic window sills, frames, slopes. Fresh composition is removed with a sponge, the remains are washed off by a cleaner for plastic surfaces. The dried layer is cut off, the residues are washed away.
• Linoleum, laminate. Fresh foam is removed by a solid subject (spatula, rubber board), the residues are collected by a sponge dipped in a cleaner.

To prevent such situations, besides the skin, it is necessary to protect the surfaces around. It is desirable to cover them with a plastic film, rags or newspapers.

The principle of operation is very simple:

1. The preparation of the cylinder is a shaking of about one minute.
2. Next, a professional balloon is put on a gun. When using a household cylinder, a plastic adapter is screwed on the nozzle.
3. Mandatory condition is moisturizing surfaces to improve adhesion. It is necessary to moisturize the ridiculous area (with a pulverizer) so that excessive moisture does not interfere with good adhesion.
4. During the cloth closeing, the cylinder must be kept in an inverted state - so the gas propylene is more efficiently pushing the contents.
5. When swinging, filling the gaps and emptiness is recommended only one-third (continuing to expand, the material will fill all the rest of the space). If for some reason the lumens formed, it is not recommended to re-foss in fresh, not yet hardened, initial foam. It is necessary to wait for complete solidification, moisten the dried material, and only then apply a new portion.
6. Upon completion of the process of filling the cracks and holes, the drying foam should again moisten a little to improve the solidification process.
7. Polymerization (frost) lasts an average of 12 hours. Although the products of some firms, as already mentioned, make it possible to carry out trimming after one hour.
8. When working with the polymer, it is important to ensure that the portions of the material do not fall out, stupid everything around. Also, retarding the balloon to the side, you must not forget that the sealant continues to pushed out and some part of it can be swap something.

Mounting foam is not a hair foam, which can be easily brushed. To clean the surface, you have to get caught.

Tip! You do not need to smear fresh foam, it is better to wait for a complete drying and then tear it off, the residues will drop in one of the following ways.
