After installing windows, doors, when docking construction slabs, an eternal question arises, namely: how to dress mounting foam ? The answer is simple to seal it with the help of sealant, putty, paints, plaster and other mixtures. A more detailed response to the putty of the mounting foam will look below.

The secret of the popularity of the assembly foam lies in its composition, the fact is that the mounting foam has polyol in its structure, as well as isocyanate. In addition, the developers are added to the composition, foam, stabilizer and dye. With that sometimes the dye puts a kind of "spoon of the testicle", because when the mounting foam of the mounting foam is a white plaster, after a few years, with non-compliance with the operating conditions, it begins to paint the plaster. Therefore, before buying a foam, you need to carefully read the composition and choose a foam without a dye.

By the way, the incorrect conditions of exploitation are usually attributed, excessive moisture content of the room where a foam is used or on the contrary, active sun rays.

So that the mounting foam does not crack, did not begin to dismiss and lose its heat-shield properties, it must be covered with a sealant or protective paint!

How to launch mounting foam

So now let's figure it out how to launch the mounting foam. The process begins with removing excess material, that is, we cut off the knife or cutter of the excess foam, and then deepen inside by 5 - 7 millimeters!. No longer needed, because if there is a large square then too much consumption of plaster, but it is less not desirable, because otherwise the plaster may be bad and gradually peel.

Selection of putty and preparation of the mixture

The second question facing us is what kind of plaster must choose, but this is the solved problem. It is best to choose a frost-resistant putty, which will not succumb to climatic influences. If you are interested in the name, then we advise you to put the brand - Rotband. Also note that it is necessary to prepare a mixture of putty before direct application, in 5-10 minutes. The instruction on the preparation of the solution is always written on the back of the packaging, but the classic use of plaster is: add a mixture into water and stir until there are no lumps, if they still appear it is necessary to add some more warm water.

After cooking plaster, we need to apply a mixture on the foam. We repeat once again that it is necessary to apply a layer of at least 6 mm. Because at a thin layer, the plaster may simply crack, and this is fraught with converted work. Before going down the plaster drying, it is necessary to take a fine-grained sandpaper or construction grid and align the surface.

Using the mounting foam, we get the opportunity to completely eliminate all the gaps after installing windows and doors. However, cutting off all the surplus of this material, we faces the task of hiding traces of the foam itself, as it looks quite unprepacently. Today we will reveal the features of this process and talk about how to solve the problem as quickly and efficiently as possible.

This chemical product is a sealant based on rampolurethane, which includes isocionate and polyol. This is the basis, however, various manufacturers may include various additives, such as catalysts, stabilizers, foaming and the like. Foam has high adhesion and extensibility, allowing it to fill out all the space. The materials with which this foam forms the strongest communication, the following:

• Cement;
• Metal;
• Plaster.

At the same time, plastic, or fatty materials, and the wet surfaces are connected with such a foam to a much lesser extent. This in turn guarantees that we do not apply it to the places where it should not be. Although, linse a similar foam from such surfaces is still frustral.

Than cutting the mounting foam

Cut foam is needed by a technical knife, which must be sharp. Try to do a cut in such a way that the rest of the foam is in short with both surfaces on the sides of it. This will facilitate further processing.

Do I need a sealer of the mounting foam?

Mounting foam is an excellent insulator, however, it needs isolation itself. If this is not done, the surface will begin to crack under the influence solar radiation and moisture. Therefore, it is necessary to hide its slice so that the foam does not collapse ahead of time (usually its insulating properties is enough for 4 years). A polyurethane can be used as a sealant as the most suitable for such a ligament. Pre-compressed sealing tape is also widely used to close the foam. However, it is necessary to understand that the construction scotch is a very dubious decision in terms of design. In addition, on the top of this tape, do not apply any finishing materials, as, having soaked with them, the tape will begin to flap.

Plaster mounting foam and other types of finishes

In addition to the above options, the following are used:

• Acrylic paint;
• Mixture of cement, white grout and sand;
• Putty. Suitable finish plasterhaving the ability to transfer negative temperatures;
• Window melting or liquid plastic.

Depending on the type of concealment of the mounting foam, these or other actions must be carried out. For example, if the foam is painted, it is possible to do it directly on the smooth cut. However, in the case of plaster, you must first provide a better grip with the surface. And for this, small grooves are cut in the foam.

The layer of plaster, which we will cover the foam should not be thin. Indeed, in this case, he will very quickly begin to crack and turn. Try to the thickness of the layer was at least three millimeters

Foam scrap is made in two cases:

• Before staining, in order to create the most flat surface. In this case, it is necessary to ensure that the cut does not start to collapse, and this requires the use of the smallest sandpaper;
• In the case of applying plaster, after drying the latter, a neat surface grout is made in order to give it an attractive appearance.

The secret of the popularity of this material is concluded in its composition, as well as in performance characteristics. The mounting foam is a polyurethane foam sealant, the main components of which are polyol, as well as isocyanate. Manufacturers are also added to a variety of auxiliary substances: a foam, stabilizer, catalyst, etc.

The main characteristics of the foam are: adhesion, exit, viscosity, primary and secondary expansion. In composition, this building material is divided into two-component and one-component mixtures. In addition, foam is a professional and household, summer, winter and all-season.

But few know that this multifunctional material itself requires protection. The destructive effect on the mounting foam is the sun rays and moisture. Manufacturers do not forget to indicate it on cans with foam. Maybe users and read these recommendations, but do not know how to close the mounting foam.

The solution is simple, the processing of the mounting foam of paint, sealant, putty or special materials will avoid future sad consequences. If they do not protect protection, it begins to crack and paint under the influence of moisture and the sun.

Of course, this process also takes time, but rather short, about 4 years old, and after this time, construction seams will lose their heat insulating properties. Under the influence of temperature differences, moisture and sun ray The porous foam body loses thermal conductivity, because Does not have hygroscopicity and in time completely collapsed.

What to protect the mounting foam?

Thus, the protection of this material is vital for it to maintain its properties, and did not have to make frequent repairs. Before making the mounting foam sealant or putty, it is worth trying a specifically produced for these purposes (pre-compressed sealing tape).

This tape is used to fill out irregularities in the opening when installing new designs. The old designs are better protected by the diffuse waterproofing tape of the membrane type.

In addition, the protection of the mounting foam is carried out:

• finishing plaster or putty, prerequisite is resistance to negative temperatures;
• solution consisting of cement, sand and white grout;
• polyurethane sealant;
• acrylate paint;
• liquid plastic;
• window smelting and other.

Before placing the mounting foam, you need to prepare the tools: a knife, a container for mixing the solution, trowel and gloves.

Before launching the mounting foam, it is necessary to cut the excess of dried material from the outside of the window or door blocks, etc.. If a putty will be used to protect, then the outer seam is better to deepen a few millimeters, if the sealant can be limited to a cut without recess. The surface of the frozen foam must be aligned.

Many novice masters are often wondering what to sharpen the mounting foam? As mentioned above, it can be any frost-resistant putty, which is sold in construction stores. It is sold in the form of a dry mix in which it is necessary to add the right amount Water to obtain a special solution.

After the preparation of the solution, it should be applied to the surface being repaired and dissolved. If the putty is imposed by a very thin layer, then when drying it can crack, therefore, it is desirable to apply this separation material with a layer of at least 3 mm.

After complete drying finishing material, working surface Locks emery paper or construction grid, To remove roughness and giving the seams of aesthetic species.

• Putty from the foam behind the time lags behind (verified). Initially, to shook down a thin layer, and how to dry and dry.
• Ceresite
• putty in latex, after drying, you can hide and paint.
• Mounting foam water does not miss. Outside the best foam to smell acrylic sealantto protect foam from ultraviolet rays, well, for complete confidence that it will not pass water - and inside and paint and paint, or go to the wallpaper
• If the seam is big, then it is better (if the design) of the slope, if the seam is up to 30mm width can be tape for sealing the bathroom adjuncing to the wall and stick along the contour. According to the technology of the installation device (GOST 30971-2002_s, the mounting nodes of the adjoining window blocks to the wall openings) - with inner Moisture-resistant steamproof gasket must be installed. You should have installed installers that installed windows. So this is their marriage and you can demand the eliminators to eliminate them (by the way, they had to establish moisture-proof gasket and foam you did not have to see after installing windows) even if they refuse you to sue them ( See the Consumer Rights Act)

Topic: Elastic shtatlevka on mounting foam

There is a piece of iron ~ 20 cm. Pts. Sly shape (emitter of acoustic locator, if interesting). make her heat-sound insulation. Skattered with water, wrapped with polyethylene with holes, and blew up under the polyethylene mounting foam. It turned out almost what you need
- Foam Machesin with hardware inside. The question is how to ensure the weatherability of this
Designs. Just paint out of the cylinder - somehow hlipping. Yes, and the surface
There are very porous places. I want to deceive some non-fruit elastic splotle
Before smooth, and then paint.

Is there such a putty in nature?

1. Children's rubber ball cut, stretch, seams from the inside to silicone, outside rubber on rubber Clee.. From above the piping to pull the reinforcing mesh on the glue.
2. In the economic store to buy two pelvis suitable form. On the side of the rubber ring or silicone, pull through the holes in the battles with nuts with nuts. Entrance inside the pelvis for cables through the waterproof cable entrance clutch.
3. Plastic bucket with lid. Economic, for (closed hermetically), from under products (similarly) ...

Loose from above epoxy resin. To protect the foam from ultravitet, add some coal powder to the resin as a filler, and the walking. And make this mixture easily thorough. Better than several layers.

Thanks for the ideas.

With a ball and verts badly, for the piece of iron sticks out of foam
From two sides (otherwise it will not work). And three legs stick out too.
With epoxy, it hurts a lot from epoxy. Yes, and fragile she is without fiberglass ...

Puttlewow, it seems to be approached. Just have her with weather resistance?
Or generally a bitumen soundproofing mastic to deceive? She is black completely ...

2Roux Full of all ribbons with sealing properties.
On a different-type basis: Izobutyl, Gerlend, PPE, and PR.
From above - reinforced tape.
Wrapped - and boulders

2samar Thank you. The form of hardware is painfully tricky. Not suddenly wrap. Although if they are strongly elastic, you can try.

Strange people ... What kind of thing is such an acoustic, which will work if a foam is planted? If this is a hydroacoustic emitter, then it will not work exactly .. Write more, for it is intended? And so shrink the heat shrinking polychlorvinyl (and maybe from another material) tube, they different diameter There are ...

2OLD_NAVY Reversive emitter. Empties the impulse (powerful). Then he takes an echo signal (weak). The dead zone is determined by the reverberation time of the antenna. This thing was done by engineers, not acoustics. Therefore, it has a pretty bizarre form outside and rings. The idea is to get out of the root and foam diet outside to the state of almost round. In the mouthpore, of course, nothing is inflated.

Due to the fancy of the shape and three legs with a heat shrink (as well as elements), I'm afraid there will be problems ..

Actually, I will stop, think on the foam covered bituminous mastic either acrylic putty. It remains only to understand that masses with heat resistance. I would like the degrees to 80-100 to do not flow and at -30 fragile did not become.

2Kranny Rygin Thank you. That is, foam + acrylic spatle + paint, or everything in silicone?
With the last, I'm afraid, the smooth surface does not achieve, and the water will stand in irregularities (freeze-melt, etc.) ..

All as for the repair of the body and dried can be "breeze". Or how i do decorative elements: Print foam, then putty mixed on dilute primer (you can add a keler), then the yacht varnish or epoxy.

2Roux Where emits? In water or in air? And, if not a secret .... What is it for?

How to close the mounting foam or protect homemade comfort!

We are already accustomed to the assembly foam - a panacea for sealing any construction seams, cracks, cracks, etc. It is used more often when installing doors, windows, as well as to fill various voids. But she does not always fit into the design of the room, so it must be done in the invisible, besides, it is quite vulnerable to exposure external environmentBut then the question arises than to close the mounting foam.

1 than to close the mounting foam - why is it necessary?

The secret of the popularity of this material is concluded in its composition, as well as in operational characteristics. The mounting foam is a polyurethane foam sealant, the main components of which are polyol, as well as isocyanate.

After installing the windows and doors, the hosts and the wizard finishers are often wondering - how to close the mounting foam? It can be hung up using putty, sealant, paint and other materials. It is important to do this correctly by applying the appropriate technique that describes below.

Mounting foam - comfortable material

Today, the mounting foam is used in many construction work. It is a polyurethane foam two- or one-component sealant, which is produced in a special aerosol can. Used in two cases:

• for thermal insulation;
• sealing seams.

Suitable for materials such as tree, glass, metal, concrete. The main component of foam is polyurethane, which was first created by Bayer in 1947. In the 70-80s began to produce first splashes and apply them for finishing works.

At the same time, in addition to polyurethane, polyisocyanate and some catalysts were added to the composition. First country this materialwas Switzerland. Later foam began to use other countries. Today it is used in Europe, Asia, USA, Russia. Such widespread is associated with unique properties material. Foam easily penetrates any gap and seam, fills the space and quickly hard. Thus, this site is perfectly protected from various adverse events.

Why do I need to protect the mounting foam?

As already mentioned, the composition perfectly fills the space inside the gap and seam. But at the same time she also needs protection. The fact is that foam is destroyed under the influence of UV rays and moisture. If you do not protect it, then the overall operational period of such a seam will be not more than 5 years. That is why after applying it additionally misses special compositions.

But the question arises - how to protect the mounting foam and which means it is better to apply? For these purposes, sealant, putty, plastic liquid, acrylic paint, can be used. At the same time, the coating should be waterproofing and countertile. That is, providing proper ventilation and protect against water penetration. Therefore, when choosing compounds, pay attention to their properties (usually described on the package). Also, some consumers are used to protect a special sealing tape. It quickly passes on the desired area and is suitable for both old and new designs.

Protection by plaster and what should I know for this?

So, on the question of how to close the mounting foam, there was already an answer. But how to do it? Consider an example of finishes using plaster. Treatment begins with removal of excess material. It is necessary in order to align the base. In the case when the use of plaster or putty is assumed to protect, it is better to additionally deepen the surface to a couple of millimeters.

The second task that occurs in front of the finishing masters is the question - how to sharpen the mounting foam? What kind of putty and plaster choose? It is better to use a frost-resistant composition that is sold in building supermarkets. A good brand is Rotband. Sold up the composition in dry form and is prepared immediately before use. And if the question is exhausted, then you can proceed to the direct preparation of the mixture. The recipe is always written on the package.

The solution is poured into the water and is carefully stirred so that there are no lumps. If you have too thick composition, it is better to add some water.

The putty is applied using a spatula or trowel. The layer should be equal to at least 4 mm. Since if you apply too thin layer, it may soon crack (usually it happens when drying). At the next stage, the coating is given for some time on solidification, but do not wait for complete drying. Then the surface is poured with a fine-grained sandpaper or a construction grid.

Please note that all the works described you can easily do yourself. It is important only to follow the instructions. Therefore, the question than to smell the mounting foam should no longer occur. Also when performing work it is necessary to wear gloves to protect the skin of the hands. All tools are washed after use. warm water. The residues of the composition are removed in a dark place.
