Sealing of wooden houses: warm seam. Seam sealant - insulation of seams with sealant in a wooden house Technology of insulation with sealant for wood

Many people choose a wooden house because of its high environmental friendliness, durability, external beauty and dozens of other advantages that are difficult to argue with. But for such a house to become truly warm and cozy, it needs proper insulation made using properly selected materials. Inter-crown insulation using natural roll materials– not the only option: insulation is no less effective wooden house sealant.

What are its features and advantages?

Types of sealants for home insulation

Sealant is a waterproof multi-component material that is designed to seal cracks between logs, as well as cracks that may form in the wood after shrinkage. Today it is not difficult to purchase a sealant for insulating a wooden house, since it is offered in the widest variety, but the home owner is faced with the problem of choice: which sealant is best for a wooden house, and what are the main differences between modern products?

• The main types of sealing compounds today are: Acrylic sealant for a wooden house is the most common solution, since acrylic-based compounds have a whole range of useful properties. performance characteristics

. This is a waterproof connection that can last for many years, as it is not destroyed by temperature changes and precipitation. Acrylic sealants are used in both internal and external insulation; they are safe for humans and do not emit volatile compounds into the air.

• They also have one more pole - excellent deformation capabilities. When shrinking, the distance between the logs may change, but the sealant will withstand any fluctuations and will not allow new cracks to form. Another common solution is silicone sealant for a wooden house: the insulation will last a long time and will be completely safe and durable. Silicone sealants may contain bactericidal components: they not only protect the house from moisture, but also prevent rotting. They can also be used for interior works thanks to the absence unpleasant odor
• and environmental safety, such sealing of seams will serve for a very long time. The third type is bitumen sealants for. Compositions based on bitumen and polyurethane can only be used for outdoor work; most often they are used for wooden roof. Their main advantage is their high water resistance; they will remain impenetrable to moisture for many years.

Sealants are selected depending on the specific conditions of use: silicone compounds are used not only for seams, but also to eliminate cracks in logs or beams, in repairs wooden furniture. This is a truly universal solution that will always be in demand.

Treatment of a wooden house with sealant is carried out after completion of shrinkage, this period is at least a year from the date of construction. During this time, the wood will dry and the logs will take their final places. Only after this, work on caulking and eliminating cracks between them will be effective. If the gaps and cracks are too large, the sealant is used together with a strand of insulating material: it fills the gap, and after that it is tightly sealed with sealant.

How is sealant treatment carried out?

Choosing a one-component acrylic sealant for wooden house construction, you can begin to treat the building and improve its energy efficiency. When choosing a suitable product, it is important to pay attention to its color: today on sale you can find compositions that match the color of certain types of wood: for example, for linden and pine you can use a lighter sealant than for other types of wood. If you have to repair an old house, darkened over time, you can, on the contrary, choose darker compositions.

The sequence of insulation work is as follows:

1. When repairing an old building, old decayed insulation is removed from the cracks, and the seams must be cleaned of dust and accumulated debris. It is advisable to cover the logs with construction tape so that later you can remove it, leaving a clean surface of the wood.
2. A polyurethane strand or other material is placed in the seam insulation materials. The cord can be additionally secured with a construction stapler.
3. The container with sealant is placed in a special gun, after which it is necessary to process the seam, while ensuring that the seam is as tight as possible without the formation of bubbles.
4. The sealant is leveled with a spatula, and its remains are removed from the walls. To successfully complete the treatment, it is better to moisten the spatula with water, this will simplify the work. After this, the tape is removed, and the logs will remain neat and clean.

This processing can be done independently without much difficulty: modern sealants Quite convenient and easy to use. After the composition has dried, the house will receive insulated seams, closed from blowing and moisture penetration. This will not only increase protection from the cold, but also increase the durability of the structure: the walls will not begin to rot, and they will be provided with many years of service.

Insulation of a wooden house - the most important stage construction. We use modern insulation“Warm seam”, the price of which is included in the total cost of the project, which we calculate before starting construction.

Insulation of a wooden house: caulk

Previously sealing and insulation wooden buildings were carried out according to the principle of caulking using tow, jute, flax and moss.

Disadvantages of caulking:

• Caulking the walls is quite labor-intensive;
• The caulking process must be repeated regularly;
• the appearance of the log house after some time is far from ideal.

An innovative method of insulating a wooden house "Warm seam"

Today, experts almost never use caulk in practice. Developed new technology called “Warm seam”, which is successfully used when it is necessary to insulate houses made of rounded logs or hand-cut houses.

Features of the "Warm seam" technology

Sealing compounds have a high degree of elasticity, due to which they easily penetrate into any cracks and cracks. After hardening, the mass forms a very strong but elastic film that can take any shape.

Characteristics of acrylic sealants:

• are not afraid of temperature changes;
• not exposed to ultraviolet sunlight;
• mold and harmful microorganisms cannot “live” on their surface;
• they do not change their color over time.

Advantages of the "Warm seam" technology

Work on insulation of internal inter-crown seams is carried out at any time of the year. At the same time, residents will not experience any inconvenience, such as an unpleasant odor, noise or dust.

Important! Specialists of the Russian Mansions company carry out insulation of external crown joints with acrylic sealants only at stable above-zero temperatures environment when the level average daily temperature not lower than +10 degrees.

Features of acrylic sealants "Remmers"

Remmers sealants have long been successfully used for insulating wooden houses in countries with harsh climatic conditions.

Important! Acrylic sealants are completely safe for human health.

Acrylic sealants in the interior of a wooden house

Walls can be sealed both from the inside and outside. Applying sealant indoors makes it possible to create original interior. Creative design projects log houses often involve the use of acrylic sealants, which come in a wide range of colors.

You can choose white, cream and beige shades or opt for a brown palette.

Important! The insulation of a wooden house will perform all the functions assigned to it if the seams are sealed by professionals who know all the intricacies technological process and using special tools in their work!

Useful articles about insulating wooden houses

And everything would be fine, yeah “in a barrel of honey, there is a fly in the ointment” . It is environmentally friendly, beautiful, and even warm. But, here are the seams... Indeed, the seams - weakness V wooden house. We have already spoken separately. But, in Lately technology is increasingly being used warm seam for wooden houses, made by hand. What is her role? Here's what experts from one company say:

« Proper insulation of a log house begins with caulking. Sealant is not a replacement, but only a good addition. The insulation must be laid flush, Valiterm must be laid, and then sealed. The goal when insulating is to fill the entire inter-crown space. But it is important to do everything right. The sealant should not come into contact with the insulation. Otherwise, over time it will crack.”

.

So, we had several questions and the first of them: what is Warm Seam technology?

Conventional methods of thermal insulation of seams in a wooden house have 3 significant drawbacks:

• Allow moisture and insects to enter the room;
• Requires regular replacement;
• Being pulled apart by birds.

How to improve the insulation system of the inter-crown space? This is why the “Warm Seam” system has been developed.

Its essence is that a special sealant is applied over the insulation and a special cord at the junction of the logs. It smoothes out beautifully and after painting (even colorless) becomes invisible. However, it protects seams well from blowing and moisture.

Required materials and choice of sealant

How much and what will be needed to carry out such work with your own hands? Taking into account the above quote, we will take into account that the initial insulation of the seams has already been done. And that means we need the following materials:

• Acrylic sealant for wood;
• Thermal insulation cord.

From the tools:

• Gun (manual, but preferably pneumatic);
• 2 spatulas (small - for the size of the seam and large for ease of removing excess from the first one);
• Brush (to remove excess);
• Possible: sponge and spray bottle (water sprayer)

“If you work on large volumes (from 200 meters), use an air gun. Your hand will get tired much less.”

Arkady Krasnov, “Siberian wooden houses.”

Now all that remains is to choose the sealant. First of all, the sealant can be sold in buckets, usually 15-25 kg, and tubes of 600 ml.

As you probably guessed, buying in larger quantities is always cheaper.

Like with Coca-Cola - what bigger bottle, the lower the price per liter.

Although, using buckets is not so convenient during the work process, and, naturally, takes longer.

The sealant also differs in color; you need to choose one that is suitable for painting.

• Eurotex;
• Neomid;
• Remmers.

There are many more options, but most people choose one of the three above. As usual, American or German ones are higher in quality and price than domestic ones.

Price

As already said, the tube is more expensive. One tube of 600 ml is enough for an average of 4-6 linear meters. It depends, of course, on the thickness and unevenness of the seam, as well as the experience of the finisher. The cost of a tube of German Remmers, for example, is 430 rubles. In this case, in the best case scenario, the cost of 1 meter of seam will be 72 rubles.

A 25 kg Eurotex bucket costs approximately 7,300 rubles. When using such a sealant, the cost of one meter will be 28 rubles. By the way, a warm seam for a wooden house can be ordered from a contractor. However, the price of such a service will cost 150-170 rubles per linear meter

. In a day, a novice specialist can do 50-200 meters. (Much depends on the size/evenness of the seams and personal abilities).

If you decide to apply it yourself or check the craftsmen for lice, the technology for applying the sealant is described below.

Application technology

• The technology essentially consists of 6 main stages:

• Laying the insulating cord. Its task is to fill the inter-crown space. It makes no sense to use a more expensive sealant for this, and filling the space with it is quite problematic. It is reasonable to use sealant as a top, fixing layer. Applying sealant using a gun. For this purpose, the tube is inserted into the cavity of the gun (or the sealant is drawn directly from the bucket). After this, the nose is cut off at 45 degrees, to the size of the seam. Next, the sealant is applied as. Some installers use tape, gluing it as a frame for the borders of the seam. This allows you to avoid staining the timber and collect excess after application. After application, the tape comes off almost immediately. However, after gaining experience, you are unlikely to need such a procedure. Professionals apply the “Warm Seam” without tape to a length of 1.5 to 2 m in one pass and very evenly.

• If excess sealant gets on the crowns, immediately remove them with a damp rag.

• Wet a small brush and use it to smooth out the seam layer.

• If there is a lot of excess, you can use a small spatula to remove it.

• Now all that remains is to go over the seam with a slightly damp cloth for final alignment.

Some people use a sponge and spray for these purposes. In this case, the seam becomes glossy.

Corners and cuts

The difficulty, especially with the first experience, is the corners and cuts. In fact, sealing such areas is carried out in the same way as straight seams.

• Measure and cut pieces of cord of the required length in advance;
• Place the cord (you can use a spatula or brush to tuck it in);
• Apply sealant;
• Carry out the alignment procedure described above.

It can be noted that in general, the application process is not particularly difficult. Although, making a warm seam for wooden houses is a very tedious job. So be patient and/or the reliable “Russian way”.

Below in a series of photographs you can see the entire process step by step.

Technology FAQ

Will the sealant be beneficial if it is applied to already caulked seams?

Certainly. The answer has already been given at the beginning of the article. Correct application warm seam and includes caulking, laying of Valiterm and cord. However, it is important that the insulation does not come into contact with the sealant.

Should smudges be removed immediately after leveling or after drying?

To avoid leaving traces, it is better to remove it immediately, but carefully so as not to touch the sealant.
Which seal to choose, inside or outside?

The short answer is that both types are needed. External, will protect the house from moisture, insects and blowing. External sealing also serves as waterproofing. However, the seams also need to be protected on the inside. For example, from moisture formed in the room itself.

Can it be applied in winter?

This depends on the type of sealant. For example, Accent-136 can be used at temperatures from -10 degrees. There are also more “heat-loving” analogues.

- As a result poor quality repairs interpanel seams of the house there was a leak on the ceiling of the walls of the apartment who should fix this and make repairs in the apartment the owner or Management Company whose fault this happened

Answer

The management company is responsible for the maintenance of interpanel joints, so repairs must be demanded from the utility companies.

Very useful video! I remembered how I was freezing this winter, and every now and then I turned on the heaters, which burn oxygen, and the heat does not last as long as I would like. I thought it was all about the cold panel walls of my house. Now I understand that sealing interpanel seams in panel houses can solve this problem. I’m already thinking about this, because it’s possible to seal the seams like this, at least from the side of the apartment.

• Viktoriya Karpenko 8 months ago

Yes panel houses constantly suffer from poorly insulated joints, which makes the house vulnerable to external temperature changes. The problem can be completely solved with a new method of insulating interpanel seams using the Warm Seam technology, which makes the house warmer and more comfortable. And of course, this way you can save money on utility bills.

• Oksana Dubokm 8 months ago

Our family lived in a panel house and I know firsthand what problems such houses have. The joints are the weakest link in a panel house. There is insulation of interpanel seams using the Warm seam technology, the results are excellent. It immediately became noticeable how cozy and warm the apartment was, that’s what modern technology means.

• Alexey Litvinov 8 months ago

Sealing interpanel seams in panel houses is, of course, not simple task for a simple resident like me. In a high-rise building, doing this on your own is almost impossible, unless of course you are a climber or you have your own equipment for working at heights. You will also need special knowledge of what materials are best for performing such work. My opinion is that in order to save yourself from all these problems, you just need to entrust such specific work to professionals. I made my choice in favor of the Assol company. I saw how they work, I really liked it.

• Elena Shcherbakova 8 months ago

Simply gorgeous sealing of seams in a panel house from the Assol company. I used the services of this company and I can say that they did everything well and conscientiously. Plus, their prices are quite reasonable, so I was pleased with everything and can confidently recommend it, you won’t regret it)

• Natalya Lapteva 9 months ago

It is almost impossible to insulate the seams from the inside. Your apartment renovation will not particularly affect the “weather”. All work must be done outside - it is impossible to avoid the involvement of professionals and, whatever one may say, climbers will be needed. It’s better to cooperate with neighbors on such repairs - it will be cheaper and more reliable: it’s not a fact that a crack that has not been repaired above the floor will not spread even more during rain and frost, destroying your entire repair. So, the whole world, so to speak, is going to seal the interpanel seams in your panel houses =) And the housing and communal services, at best, will make cosmetic repairs.

• Vitaly! 9 months ago

As a construction contractor, I want to say that insulation of interpanel seams using the Warm Seam technology from this company is the most favorable in terms of price - quality - time performance!

For the first time I saw how to seal seams in a panel house. Last year, our house underwent a major renovation, during which the seams were also sealed. Now the apartment is warm even on the most very coldy. An excellent and high-quality insulation method.

• Zamil Gainutdinov 9 months ago

It’s good that they have now begun to master such a method as sealing seams. Many problems can be left behind at once. The video clearly shows how specialists competently insulate the apartment itself and seal the seams with minimal costs. I think many will be interested in this and no one will refuse such a warm sealing of seams.

• Anatoly Avd 9 months ago

Thank you very interesting video! I enjoyed watching it. Sealing seams in panel houses is a very important topic. If you do everything right, the house will remain warm. I'll take note

• Ivor Sovin 10 months ago

Weakness panel houses- these are the joints. Over time they are destroyed. I have the same story. The house is over 30 years old and the seams urgently need to be sealed. But I don’t want it just for one or two years.

I especially watched all your videos on the channel, which show sealing seams in a panel house. Still, this technology is the most correct and durable solution; I choose the “warm seam”.

• Alexander Byzov 10 months ago

Great video. Not only the work of climbers, but also the “Warm Seam” technology itself is shown in detail. If only management companies could use this...

• Andrey Solo 8 hours ago

Recently moved to a newly built apartment house. This is just some kind of horror! It's blowing from the windows, the walls are freezing, and the wind is blowing in the connection between the panel and the stove. How is it even possible to build something like that? A friend recommended your company. He says that sealing interpanel seams using the “Warm seam” technology is 100% justified. We need to talk with the other residents and plan to insulate the house completely (five floors, three entrances). As soon as I agree, I’ll write to you!

• Vitaly Libkind 8 hours ago

I really liked the technology - Sealing technology Warm seam. It became clear how you can insulate and ensure comfort in your home. As I understand it, the work can be carried out in a panel house and the insulating material maintains the temperature and repels moisture? I plan to contact your company and calculate in more detail the cost of sealing interpanel seams. Thanks for the clear and useful video and technology.

• Alena Melnichuk 1 hour ago

I live in a panel house. It was impossible to live in winter until the seams were sealed. The guys did everything perfectly. Fast, high quality, warm. Now we live like in a den, not a single breeze can get through. I hope their work will last for another year and another generation! As far as I know, all the material is of very high quality and resistant to temperature changes!

• Andrey Solo 3 days ago

Current video! I myself live in an old panel house, and as a result, with all its problems. Namely, cracks, crumbling plaster, etc. The year before last we ordered a team that simply plastered the seams with regular mortar. This winter everything fell apart. Now the whole house is thinking about insulating interpanel seams using the “Warm Seam” technology. Let the guys do it and forget about these cracks! I wanted to ask, are you traveling to the Moscow region, to Tver?

How to properly insulate interpanel seams in a panel house:

If the technology for sealing seams is violated, or if low-quality material is used, it leads to drafts, freezing of corners and walls, as well as leaks.

Primary sealing

It is carried out during the construction of a building and includes the following stages:

The seam between the panels is filled with foam; it provides not only insulation, but also additional waterproofing;

Vilatherm is placed in the seam. This is insulation with high rate elasticity, made from foamed polyethylene. The material may be cylindrical, sometimes with a hole inside. Due to its elasticity, the material can withstand repeated stretching and compression, which is important when new house undergoes shrinkage. When laying the material, you need to ensure that it fits snugly concrete surface. If connection is made to vilates of different diameters, then top edge the wedge is cut downwards and the bottom one is cut upwards.

A sealant (mastic) is applied over the vilatherm; if all work is done correctly, the seam should be completely sealed.

Often, insulation and sealing of the seam is carried out without the use of foam; this is acceptable and does not greatly affect the final result.

Now let's look at what mistakes are most often made when sealing interpanel joints?

For insulation, only polyurethane foam is used. Some companies consider this a simplified option, but our specialists do not use this technology, as it has disadvantages. Over time, the house will settle, causing the slabs to move. Polyurethane foam is not elastic, therefore, as a result of the movement of the slabs, the integrity of the foam will be compromised, which means water and cold will freely penetrate into the seams.

Use of low-quality Vilaterm. The use of high-quality insulating material is a very important fact, so we check the quality of vilatherm every time we purchase it. In our practice, there have been cases when “raw” vilatherm was purchased from the manufacturer; such material does not provide a tight fit to the panels, that is, the material simply falls out of the seam.

Using vilatherm of the wrong diameter. When laying, it is important that it fits tightly to the walls of the seam and is in a compressed state.

Incorrect connection of insulation. One of the common mistakes that leads to the destruction of the sealing material and the opening of the seam.

Secondary sealing

Repeated work on sealing the joints between the slabs can be carried out using two technologies:

No seam opening. New sealant is applied to the old sealant (mastic joint repair) or over the concrete joint. In this case, it is very important that the seam is cleared of foreign debris and elements that are weak to adhere to. A carpet brush is used to clean the joint, after which the seam is treated with a solvent.

The second option involves opening the seam and its complete cleaning with the removal of old sealing material. For cleaning, a hammer drill and a chisel and hammer are used to remove old material. After which the seam is degreased and goes through the stages of primary sealing.

Often, when carrying out this procedure, companies with unqualified employees make a mistake - poor-quality cleaning of the seam from old material.

A little about the technology of sealing interpanel joints

The simplest and cheap option sealing is the coating of joints, but unfortunately, this method does not bring the expected results, moisture penetrates the seams and enters the home, drafts continue to walk along the walls and bring cold into the home.

The fact is that during rain, a large amount of water collects on the roof of the bay window and it flows along the seams, constantly leaking into the apartments, especially in areas where a vertical seam intersects with a horizontal one. The surface sealing method is often used by home management companies, where the main thing is to make the work look like it is done, and not to do the job properly.

Sealing seams in panel houses

In this case, it is assumed that the joint between the panels is completely filled, where the final stage is the application of a sealing layer of mastic. When the material is completely foamed, it comes out, so it doesn’t make any sense to lay Vilatherm and mastic right away. You need to wait a few hours and better than a day, until the foam gets stronger, then you need to remove its excess, lay the vilatherm and apply mastic. If the joints are filled through holes that are pre-drilled, then the technology is the same. Foam is injected into the holes, which are then tightly closed. The foam, not finding a way out, is forced to fill all the voids inside.

Is it necessary to open the seam?

There are a number of factors under which the seam must be opened, namely:

• The material from the seam disintegrates when struck with the sharp edge of a climbing hammer;
• The seam is surface plastered and a light layer of sealant is applied to it;
• The wall is very old and the material falls off even with a light touch.

Such seams must be opened, filled and sealed. If the seam is securely concreted or the slabs fit tightly enough to one another, then tearing down the walls is not recommended. It is more advisable to drill neat holes and foam the voids. Some people believe that in order to ensure thermal insulation of the seam, it is necessary to lay vilatherm. This is not so, the fact is that vilatherm itself does not provide heat, it only protects the seam from the penetration of cold by “sealing” the joint. If the seam is foamed correctly and reliably, then heat leakage will not occur.

Features of sealing interpanel seams

Today, before starting renovations on apartments in a new building, owners have to wait several years for the house to settle. As a result of settlement of the house, voids and cracks form between the slabs, which must be repaired. Houses that were built in cold period have a number of disadvantages. The panels often did not always have time to dry thoroughly and reached their condition already during the construction process. As a result, due to temperature changes and high humidity inside the slab, its integrity was violated, since in frosty weather the water inside the concrete froze and destroyed the slab.

Sealing of joints between panels should be carried out during the construction stage. Work should be carried out from elastic material with good resistance to negative impact environment, because practice has already proven that the structure hard materials quickly collapses due to the constant (even microscopic) movement of the panel slabs.

Seam sealing at a professional level

To ensure thermal and waterproofing, it is necessary that all joints and cavities between the slabs be filled and sealed. Only properly sealed seams provide comfortable and healthy living conditions. As practice has shown, the most effective method insulation today is a “warm seam”.

In the past century, the seam was filled with tow and rubber; recently, new materials and techniques have appeared on the market, which have made it possible to significantly improve the technology of sealing seams and guarantee high results. For this purpose use:

• Swellable cords made on the basis of hydrophilic rubber;
• Common cement mortar;
• Dowels and specialized profiles.

But such sealing methods cannot give good result because of:

• Different thicknesses of gaps between plates;
• Chips and microcracks of slabs;
• A defect that could occur as a result of non-compliance with construction technology.

Houses made of sandwich panels once received an unfortunate practice. The first buildings built using the new method had to be strong and warm, since the structure was made of two strong slabs. But over time, it turned out that there was an empty space between the panels, although in theory it should have been filled with insulation, in practice it was not there, as a result, air accumulated in the empty space, which created drafts. Because of large quantity Because of the empty cavities, such houses did not warm up well and cooled down quickly. Condensation led to the formation and active reproduction of mold and mildew, which became faithful neighbors.

Step-by-step sealing of interpanel seams

Sealing seams in buildings of this type is a very painstaking and time-consuming job that requires experience and specific knowledge. Our company employees, thanks many years of experience managed to master the technology of closing seams for such houses.

To reliably fill the seams, our employees use special foam, which, when expanded, penetrates even small cracks and reliably fills all voids. Vilater blocks the foam from escaping to the outside, as a result, the entire flow goes inside, and the sealant reliably protects the seams from moisture penetration.

Protection of the upper floors should begin with sealing the seams

The reputation of panel houses suffers greatly due to poor waterproofing, this primarily concerns top floors. In most cases, the space between the slabs in such buildings is not filled with anything, and this is a fact proven by practice and experience. Besides roofing material balconies and loggias do not meet waterproofing requirements.

The technical floor becomes a place where it is stable, after each rain it accumulates rainwater, which penetrates into apartments through drainage channels and empty seams, and the upper floors are the first to suffer.

To free your apartment from the constant penetration of dampness, drafts and cold from the roof, it is enough to properly insulate the joints and repair the roof on the loggia. To do this, craftsmen remove the old material and lay in a new one that has good strength and elasticity. Additionally, the work uses a burner and special modern waterproofing materials. Next, waterproofing of vertical joints in the area of ​​the customer’s apartment is carried out on all floors. Afterwards, the joints between the panels are cleaned, where vilatherm and polyurethane foam are laid. Afterwards, the seam must be thoroughly coated with waterproofing material - mastic. Only compliance with this technology allows us to guarantee high results. waterproofing works and provide dry and warm walls in the premises.

edge concrete wall the joints are often uneven and jagged, so if the joints are not sealed carefully, they begin to leak. The problem is that the seams with inside the slabs are not available for work, therefore the only way out is thorough waterproofing of joints from the outside.

Sealing seams in different types of houses

Sealing technology is selected for each home and case individually, since there are many factors that must first be calculated and taken into account. At the same time, craftsmen also consider the economic feasibility of using one or another sealing method.

Our company uses the “warm seam” technology for its work; today this is perhaps the only reliable, proven method that gives high results. The secret of our company is that we use our own, improved and time-tested technology for waterproofing seams. We use Vilaterm as a sealant, a material characterized by high wear resistance, Macroflex sealant and Oxyplast mastic.

Previously KOPE type houses were built from sandwich panels that were empty inside. The tightness of the adhesion of such panels was simply terrible; as a result, the houses were not distinguished by good thermal insulation and airtightness.

Let's say right away that sealing seams using foam does not bring desired result Due to the specifics of the material, the foam did not linger in the seams after filling, but spread throughout the interpanel space. To achieve good tightness, a vilatherm seal is used. This material has already proven its effectiveness in ensuring tight sealing of seams and sealing.

In houses of the item 44 and item 44t series From time to time, problems arise associated with chips on the slabs or the formation of large seams between the panels, through which heat leaves the house, a draft penetrates from the street and condensation forms. In winter, such walls are not protected from the cold, as a result, fungus and mold become permanent residents in such apartments, and drafts also add to the dampness.

In such cases, interpanel joints are sealed using the “warm seam” technology. If the width of the joint does not allow the use of Vilaterm insulation, the seam is reliably foamed and covered with sealant on top. Construction foam has good environmental resistance and can long time perform its functions.

To be fair, it should be noted that blown seams are not only a drawback of panel houses. Monolithic brick buildings also face this problem; poor sealing is especially often observed at the junction between the brickwork and concrete-monolithic floor. Similar problems also often arise at the junction points brickwork and windows. By personal experience we can say that such seams must be sealed very carefully, using not only foam, but also sealed plaster.

Sealing joints that were previously plastered

Often, instead of sealing, utility workers simply plaster the walls and seams, but these actions do not solve the problem, the void between the seams remains, water and cold air constantly penetrate into apartments, as a result, the home is cold and uncomfortable, fungus and mold develop, which not only allows you to create comfortable living conditions, but also negatively affects the health of residents. Over time, dampness destroys the plaster layer and cracks open.

Of course, it is not always necessary to open the seam completely. Such measures are taken if the joint between the panels is narrow or the plaster is held tightly, then it is used construction foam. Holes are made in the plastered seam, every 20-30 cm, foam is released through them, which penetrates into all the cracks and fills the entire space. Afterwards, a layer of sealant - mastic - is applied to the plaster, this coating will provide additional protection from moisture penetration.

The design of loggias and balconies implies the presence of joints between the slabs and the walls, through which water can penetrate during rain. Constant dampness negatively affects materials, destroys them, develops fungus in them, and mold appears on the walls and ceiling. If the loggia is also blown out, then the furniture and materials on them begin to deteriorate, and there is nothing to say about comfort.

To eliminate drafts and moisture penetration inside, you need to provide sealing. Before starting work, the loggia must be carefully examined by employees of the sealing company, which will allow you to first draw up a competent work plan and select the necessary materials.

The main reasons why water leaks onto the loggia:

• Absence or poor quality sealing;
• The sad condition of the roof of a balcony or loggia;
• Lack of tides or their unsuitable condition.

Taking into account the above reasons for leakage, sealing work is reduced to processing the joints in the area of ​​​​contact between the wall and the ceiling slab. If this is not done, then sooner or later the water accumulated on the slab will begin to flow around the joints and fall directly onto the loggia.

Sealing seams between the wall and the window frame

Often after installing windows, water leaks appear in those places where the frame adjoins the wall.

The main reasons for the formation of cracks are most often:

• Improper application of sealing material to the surface of the foam;
• Lack of tides or their poor condition;
• There is no sealant between the ebb and the wall.

What advantage does sealant have over other building materials?

Wooden houses can be insulated different ways. Such as caulking, covered with thermal panels or a relatively new method - acrylic sealant, with the help of which a so-called “warm seam” is created. This technology will protect a wooden house from drafts and cold in winter. The sealant contains rubber, which gives elasticity and prevents any small hidden cracks from cracking further.

Advantages of acrylic sealant

Warm seam - modern technology insulation of the house, which reduces the possibility of freezing of the walls of the house. This technology has a number of advantages, including:

• You only need to insulate the walls once; you don’t have to go back and forth;
• High resistance to temperature changes;
• Thanks to special staff prevents wood from rotting;
• Minimum finishing time;
• The material is safe as it does not emit toxic substances;
• No smell;
• Wide choice of colors;
• Saving home heating costs.

An environmentally friendly sealant allows the wood to “breathe” and will preserve it for a long time. natural properties logs and protect the house from the cold.

Stages of sealing a house

To carry out sealing work, the walls need to be prepared, the house needs to be sanded and painted. After which you can begin insulation. The application of sealant begins with cleaning the surface of the log house. The next stage is fixing the heat-insulating cord, which is made of polyethylene.

It is recommended to take the cord wider than the seam by about a third. It insulates the seam and reduces the consumption of sealant. Fix the cord using a construction stapler or small nails using a pneumatic gun.

After laying the cord, apply it with a gun, and then smooth it out with a spatula and clean it with a rag. It is recommended to apply the sealant in a layer 4-6 mm thick, while the adhesion area of ​​the sealant to the wood should be at least 4 mm on each side.

Hardening of the sealant takes up to two days at a temperature of 23 degrees above zero. When curing for 4-20 hours, the applied material must be protected from rain and moisture penetration. After complete curing, the warm seam forms a rubber membrane that can be smoothed and coated with glaze compounds or acrylic-based paints).

Use this type insulation is possible only after complete shrinkage of the log house. Internal sealing is carried out after heating season, that is, after the first season of operation of the house. In addition, using sealant, you can fill the cracks in the log and at the ends that appeared during the shrinkage of the log house. The MariSrub company uses time-tested sealants from the German company Remmers, which do not fall off or crack during the operation of the house.
