Panel buildings have many advantages, but, like any buildings, they are considered to be well-built and suitable for comfortable living only if they have high energy efficiency. The latter directly depends on how well the joints between the individual structural elements are sealed. Mastics are the most popular for sealing seams between panels. they eliminate gaps, which reduces heating and air conditioning costs.
Technical characteristics of mastic
These sealing compounds have the following important properties:
- Good degree of adhesion. The composition adheres well to the base, but only when it is completely cleaned.
- Resistance to adverse conditions. Mastics tolerate aggressive influences well high humidity, low and high temperatures.
- Long service life. Sealing compounds from most well-established manufacturers reliably protect seams in panel houses without the need for updating for many years.
- Easy to use. Modern mastics are quite easy to apply and require minimal labor.
- Cost-effective and accessible. An important property of any sealing composition is its low consumption per linear meter, as well as its relatively low price.
- Can be used all year round. Most mastics are suitable for sealing seams between panels, even in winter time year, and not just in warm weather.
It should be taken into account that erosion of the seams can occur due to the lack of high-quality drainage for water when it flows along the interpanel joints.
Varieties
On modern market sealing compounds for sealing joints in panel houses are represented by three subtypes. Each category has its own characteristic features, is produced by both domestic and foreign manufacturers. Some are single-component, that is, compositions that do not require preparation. Others, on the contrary, are two-component and require preliminary mixing of the components of the kit.
Butyl rubber mastics for sealing seams
They differ in the presence of organic solvents. This composition allows you to use mastic in winter. The lower threshold is -20 degrees Celsius. If the frosts are more severe, it is no longer possible to carry out work on sealing seams using butyl rubber mastic.
Sealing compounds, which are butyl rubber diluted with an organic solvent, are intended for sealing external seams. This limitation is due to the fact that the hardening of such mastic is accompanied by the release of toxic substances. In addition, until the composition completely sets, it is a fire hazard.
The listed properties of mastic impose certain safety measures and precautions when sealing seams. Until the composition has completely hardened, there should be no open source of fire or even lit cigarettes nearby. Specialists working with these mastics must wear gloves, goggles, and special clothing. Without funds personal protection These compounds become dangerous to humans.
The service life of the composition, guaranteed by the manufacturer, is eight years.
Polyurethane mastics
This is exactly the type of sealant that is represented by one- and two-component compositions. The latter differ from the former in that they can be stored for a much longer time than those that are ready-to-use polyurethane-based compounds.
A characteristic feature of this mastic is that it has the highest degree of adhesion (adhesion) to various construction materials. structural materials. This is not only concrete or brick, but even metal and glass. There is currently no better quality sealant for sealing joints in panel houses.
Polyurethane mastics have one significant drawback - their high cost, which makes sealing seams using it quite expensive. Such “extravagance” is fully justified not only by excellent performance characteristics, but also by a long service life, reaching fifteen years.
In other words, polyurethane-based mastic will last twice as long as butyl rubber. This means that you will not have to incur additional costs to update the seam sealing. There are brands that last even longer.
Acrylic sealing mastics
They represent a separate class of sealants, which are almost never used for sealing external seams in panel housing construction. This is due to the fact that mastic-based compositions cannot withstand being washed out by water. On the other hand, they are popular for interior work.
Acrylic sealants, even during the hardening process, do not release toxic substances into the surrounding space, have good adhesion, and are also absolutely fireproof. But, unfortunately, they are not suitable for sealing seams in panel buildings.
They are widely in demand in eliminating cracks in apartments, offices, and houses, since they provide not only high-quality internal sealing, but also significantly increase the noise insulation of rooms.
Preparation of mastic
There is no need to weigh the components before use as the sealing material is supplied as a kit. Measurements are carried out only when the mastic is prepared in small quantities, that is, when updating seams in a small area panel house. After mixing, the mastic acquires a consistency that resembles rubber.
It is no longer possible to reverse the process of transition of the sealing composition, which must be taken into account. The time interval or “viability” of the composition, when the paste-like mass becomes like rubber, is indicated for each batch of material in the accompanying passport. It must be taken into account when sealing joints over a large area.
Coloring mastic
Coloring the sealing compound is a responsible process, but to give a finished look to a panel house it is usually necessary or simply mandatory. Butyl rubber mastics lend themselves best to painting. They can be painted with almost any paint. Polyurethane compounds, on the contrary, are very capricious.
Typically, information regarding what type of paint should be used is clarified with the manufacturer. If this is not possible, test staining is carried out using several types of paintwork materials. The main thing to consider is important rule, which lies in the fact that only completely hardened mastic can be painted.
In any case, you must read full information about sealant and choose paint from those recommended. Otherwise, if it cracks ahead of time, it will ruin appearance buildings. In addition, the wrong choice of coating materials can lead to the fact that material components can penetrate into the mastic and reduce the quality of sealing.
Application of sealing mastic
Sealing seams in panel houses can be done either with a spatula or a special construction gun. The latter tool makes the process much easier, especially when the total length of the joints is quite large. When the mastic is laid in the seam, the surface of the composition is given a concave shape using a wooden spatula. Its surface should be periodically moistened in a weak soap solution. This will reduce the adhesion of the mastic to the surface of the tool.
Do not use too much liquid. Excess soap solution can damage the surfaces of the sealant. This is most relevant for polyurethane-based mastics, which contain components that actively react with water. Along with this nuance, it should also be taken into account that the thickness of the seam must be maintained at all joints between the panels. The better the work is done, the less mastic is used.
In the winter season, heat preservation in apartments, offices and production premises. And the first solution that suggests itself is sealing interpanel seams in panel houses, all kinds of joints of facade elements, eliminating drafts and eliminating leaks. How by-effect If the above-mentioned malfunctions of building facades, roofs, walls, mold and mildew may appear, which is a direct threat to the building itself and the health of the people in it. The reasons for increased heat loss and increased humidity in the room can be very diverse, but there are several most common generalizations.
There are also often mistakes made during the construction process. It should be added that these elements not only worsen the indoor microclimate, but can also become a source of rapid wear and tear of the building due to the accumulation of dirt, moisture, and other things. There is only one solution - sealing interpanel seams. This procedure may consist of several stages, be primary or secondary (this affects the range of work performed), and so on. In each specific case, an individual program is selected to solve problems with object insulation.
Sealing interpanel seams - everything is solvable
However, you shouldn't worry about this. If you notice the source of heat loss in time and eliminate it, your home will be warm and cozy again. And it will also serve you for decades. Professional sealing of interpanel seams in Moscow is best opportunity prepare your home for winter frosts.

Correctly performed sealing of interpanel seams is the key to high-quality operation of the home, thanks to comprehensive protection against atmospheric influences and leaks. Depressurization requires acceptance emergency measures to eliminate deformation and destruction in the area of joints. Moisture penetration can cause walls to freeze, condensation to form, and mold and mildew to appear.
Sealing of interpanel seams is carried out when the integrity of the joints is violated. The reasons for depressurization may be:
- non-compliance with standards construction technology during construction of a structure;
- displacement of panel blocks due to uneven shrinkage of load-bearing elements of the building;
- deformation of panels under the influence of sudden temperature changes;
- intense influence atmospheric precipitation, conditions of high humidity and low temperature conditions.
The technology for insulating interpanel seams should occur in stages, in accordance with established rules. Deformation changes require opening the groove between the panel sheets.
Insulation and sealing work is carried out using standard technology:
- Cleaning and stripping surfaces of old insulation, dust, paint, mastic.
- Repairing cracks in the interpanel space.
- Seam filling heat-insulating material(polyurethane foam). After application, during the hardening process, the composition expands, filling pores and voids in inaccessible areas of the seam. When carrying out work, the joint surfaces must be clean and dry.
- Laying Vilaterm insulation. The material has a dense structure, has optimal thermal insulation and elasticity characteristics, and is easy to install. The insulation is laid without breaks, filling the entire length of the seams. It is necessary to leave space for sealing after laying the material.
- Finally, the seams are treated with sealing compounds (waterproofing mastics), which seal the insulation after installation from external influences.
It is recommended to carry out repair work on sealing in a temperature range from -10°C to +30°C, and in the complete absence of precipitation. Violation of external conditions during installation will lead to the fragility of the waterproofing.
Sealing of interpanel seams from inside the apartment is carried out if it is impossible to carry out high-altitude work With outside dwellings. The room should be cleared of furniture. Next, a superficial opening of the interpanel joints is carried out and the scope of work is determined. If the sealing material is in satisfactory condition, it is advisable to foam the groove between the panels by preparing holes along the seam.
In the absence of insulation and deformation of the panel blocks, it will be necessary to deeply open the seams. The technology for carrying out the work is similar to external repair work. The process of external sealing of interpanel seams of houses involves the use of an algorithm for primary and secondary processing of block joints.
Sealing of primary type interpanel seams is carried out in new buildings. Sealing of joints is carried out by laying insulation. Applicable innovative material vilatherm, presented in the form of rounded polyethylene foam tubes, or penoflex (mounting foam). The outer surface of the insulation is covered with a protective layer of waterproofing material - mastic.
Careful processing of interpanel seams in panel houses guarantees high-quality insulation and moisture protection against aggressive influences weather conditions. Optimal choice will become sealing materials for facades that are resistant to temperature changes, maintaining their properties for a long time.
Secondary sealing of external interpanel joint
Sealing of secondary panel seams involves repair work in areas where the joints between panels have already been treated. Repeated coating updates are recommended every 5-7 years. The use of sealants and the type of repair depend on the current condition of the seam.
The absence of severe damage, satisfactory quality of the coating, allows us to limit ourselves to updating the outer sealing layer. Signs of deformation, deep destruction, require major repair work, which involves opening the seams and removing old fillers. In this case, sealing of interpanel seams is carried out using primary technology.
Features of the technology for insulating interpanel seams “Warm seam”
Insulation of interpanel seams in the presence of significant signs of destruction is carried out using a three-component technology “ Warm seam" The execution method differs significantly from standard repair work. The main material is polyurethane foam, which is not used in other options.
The sealing composition makes it possible to increase the resistance of interpanel seams to chemical and mechanical influences. Polyurethane has a low ability to accumulate moisture. After the foam hardens, a material with optimal thermal insulation characteristics is formed. With the help of polyurethane foam, it is possible to completely seal the seams of houses, thanks to the filling of all hollow spaces, even in the most inaccessible places.
As a result of the use of three-component sealing technology and insulation of interpanel seams from the inside, it is achieved optimal level protection from moisture and wind. In order to avoid the accumulation of condensation in the area of the interpanel joint, the method of insulating interpanel seams from the inside must be carried out in stages, taking into account all the basic norms and requirements.
Initially, the surface is cleaned and the old composition is removed. The prepared groove is treated with polyurethane foam. The sealant is laid until it hardens, after which waterproofing mastic is applied. Insulation of interpanel seams in panel houses allows you to prevent irrational heat loss, increasing the room temperature by 3-4°C.
Rules for sealing interpanel seams
The work must be carried out taking into account the individual characteristics of the state of the interpanel space. The rules for sealing interpanel seams will help you achieve the desired result by performing the technology efficiently, in full compliance with the standards.
Standard rules for insulation and sealing of interpanel joints:
- The presence of leaks in the area of the end surface of the wall requires overhaul for sealing interpanel seams at the end of the facade and the longitudinal wall.
- Leakage in the area of the vertical joint is eliminated by completely replacing the vertical joints with adjacent horizontal sections along the entire height of the building facade.
- The presence of deformation of the horizontal interpanel seam requires repair work in the area of three or four panel rows of the structure.
Sealing of interpanel seams must take into account a certain degree of load on the joint areas. The sealing surfaces are subjected to alternating tension and compression. The insulation material and sealant are selected in relation to shrinkage and structural vibrations.
The impact of the load increases commensurate with the width of the seam, so it is recommended to lay a layer of sealant that is twice as small as the width of the joint space between the panels. When choosing a material, you should also take into account the characteristics of the compositions, the degree of resistance to loads and external influences.
Materials for working with seams
The main purpose of materials for sealing the interpanel seam from the inside is to qualitatively eliminate cracks and damage to prevent moisture from entering the joints between the panels.
Seam sealing treatment is carried out using special materials:
- mastics, sealants;
- waterproofing plaits;
- polyurethane foam;
- vilaterm.
The choice of a specific material depends on the condition of the interpanel seams and the type of repair work. Sealant (sealing mastic) is used for cosmetic repairs of sealing interpanel seams.
The absence of damage to the seams of the insulation allows only updating the mastic layer. It is not recommended to use cement-sand mixtures or bituminous materials due to their low performance properties. Cracks and chips form on the surface of hard coatings.
Major repairs to the sealing of panel and interpanel seams are carried out when full disclosure joints and replacement of insulation. Next comes sealing and painting. Important to consider performance characteristics insulation material, degree of strength and resistance to external influences.
When sealing interpanel seams, the materials must be insulation, which will provide reliable thermal protection and serve as the basis for laying mastic or tape. The optimal choice would be a composition based on polyurethane foam.
Freezing and moisture getting into the interpanel seams can cause serious damage and cause an uncomfortable atmosphere in the home. Timely and high quality renovation work for insulation and sealing of joints, will eliminate unpleasant consequences, increasing the durability of the structure.
At least 50 percent of the housing stock is apartment buildings, which were built using panel technology. At one time she provided housing for many people in need.
The need to seal the seams of a panel house
The main problem of such buildings is the leakage of joints formed by structural elements. This indicates that in some cases the need to seal seams in a panel house is especially acute. Thanks to these procedures, it is possible to reduce energy consumption, get rid of mold, and also improve the microclimate in the premises of the house.
Features of sealing seams during construction and methods of repair
Sealing seams relatively recently was considered not such an important task, which is why little attention was paid to this issue. Majority construction organizations To carry out these works, I used traditional glass wool or tow, in best case scenario sealants based on rubber were used. Then the seam was filled with a mixture made of sand and cement. On last stage the surface was covered with bitumen-based mastic. For the reason that any building construction during operation it shrinks, the sealing of the seams is broken, even a very slight displacement of the panels relative to each other contributes to a change in the original geometry of the joint. Moisture gets into the seam, which contributes to the destruction of the cement mortar, opening up space for external influences: precipitation and winds. Sealing of seams after such phenomena can, of course, be done using the method described above, but there will be no guarantee of durability. Depending on the condition of the joints between adjacent panels, today it is customary to use several methods.
Carrying out repair work
Sealing the seams should be done after the craftsman is able to determine the condition of the groove. Thus, if the concrete or cement filling is not badly damaged, then cosmetic repairs are carried out. This access method is the most cost-effective, but it does not guarantee efficiency. If the main area of the seam remains in good condition, but has some defects, then repair work is carried out using a technology that involves partially opening the seam at the original level. The optimal, but very expensive option is to seal joints using a technology called “warm joint”. It is necessary to mention that sealing cannot be performed from inside the room. Even if such work was carried out, it cannot be called high-quality. All such manipulations must be carried out exclusively from the façade of the building.
However, when renovating an apartment, you can fill open joints using mortar and insulating material. This will achieve a certain effect, but the situation will not change radically. Among other things, the interpanel seams must be sealed over the entire height, otherwise there will be no guarantee that water getting between the panels will not destroy the already repaired surface. For this reason, it is preferable to cooperate with neighbors; it will be cheaper and more reliable due to the volume of work carried out. The cost is influenced by the need to attract climbers to carry out these manipulations on multi-storey buildings. It is necessary to take into account that the use of lifting towers and other devices is often impossible.
Cosmetic seam repair
Sealing of interpanel seams can be done without opening. This option is considered the most inexpensive. It should only be used when perfect condition joint covering. Initially, the condition of the seam is analyzed; using a spatula, it is necessary to remove the layer of old mastic or resin. If the cement on the base is reliable, then to save money you can limit yourself to cosmetic finishing. However, sealing panel seams using this technology is not correct. After the seam is cleaned, it must be treated with primer deep penetration, it is preferable to use a composition that has fungicidal additives. If necessary, the damaged areas can be repaired with mortar. Then the entire surface must be treated with water-repellent mastic. In order to seal the seams in a panel house, you can use one- or two-component compounds; the choice will be up to the customer. A number of experts advise using two-component compositions made on the basis of polyurethane.
Features of cosmetic seam repairs
Due to the fact that sealing the seams of a house can only be done efficiently from the outside, you need to thoroughly prepare the components of the mixture, which are stirred using a mixer. The sealant is applied to the seams using a spatula; the width of the tool is selected depending on the dimensions. It is recommended to seal the front edges of the panels masking tape, which is eliminated after treatment with mastic. This allows you to get a more aesthetic surface.
Carrying out repairs with partial opening
Sealing seams wooden house can also be done with partial opening of the seam. If some part of the coating is damaged or there is confidence that there is no sealing material behind the screed layer, then sealing is carried out using a technology that involves removing the cement coating. If a small part of the seam is opened using this principle, you need to drill holes every twenty-five centimeters. You need to use a drill for this. After the void, they are filled with polyurethane foam, for which it is preferable to use a special gun, which will reduce material consumption. After the foam has hardened, its protruding parts must be removed. The seam is treated with a primer, hidden areas and holes are plastered. As final stage the seam is treated with mastic.
Warm seam sealing technology
The best way to deal with leaky seams is a method called “warm seam”. The cost will be higher, but the quality of the work will be high. Let's look at it in more detail.
Features of the work
Manipulations must begin by opening the seam along its entire length, the sealant must be removed, and the edges of the panels must be restored, if necessary. The surface must be treated with a primer. The seam must be sealed with foam, taking into account its ability to expand. After the foam begins to increase, you need to lay a sealant made of polyethylene foam on top. This will prevent foam from escaping. This seal is produced in the form of hollow tubes, but solid ones can also be purchased. The dimensions of this material should be fifteen centimeters larger than the width of the seam. It is installed in place using a spatula; the element must be pressed into the layer of polyurethane foam. During installation, care must be taken to avoid the possibility of damage to the material. In this case, tape can also be used to seal the seams. This technology is considered the most effective and modern today. Its use allows you to thermally insulate the seam, making it waterproof, which will ensure reliable protection home from the influence of external negative factors, will increase the service life of the building. Sealing of joints in multi-storey buildings should only be carried out with the help of professional support.
Finally
You can experiment with sealing seams only at the level of 1-2 floors, having the opportunity to install stable scaffolding. In other cases, it is reasonable to entrust these manipulations to industrial climbers. After all, it will be very difficult to physically carry out such work, even with the appropriate equipment, without having professional experience behind you. In addition, this is very dangerous, and at least the result of the work carried out independently may not suit you, because you do not know about the subtleties and basic rules that should be followed.

3. Types of sealing of interpanel seams
3.1. Primary sealing of external seams
This method involves carrying out work in new panel houses after construction is completed. The technological seams between the panels are first filled with vilatherm or expanded polystyrene, which provides thermal insulation for the building. Then a layer of mastic is applied to the resulting surface in order to protect the insulation from the negative effects of the atmosphere.
3.2. Secondary seam sealing
To repair the old, already existing seam layer, secondary treatment is used. It can be done in the form complete replacement insulation, and partial. In the second case, only the sealant is dismantled, which is no longer capable of providing high-quality insulation.
3.3. "Warm seam" technology
Warm seam - the most correct method repair of sealing of interpanel seams. The seam is made again the way it should have been originally.
Seams often leak inside - somewhere at the top the seam has become leaky and water begins to spread inside the seam, down and to the sides. A warm seam is a guaranteed solution to cold seams and their leakage. Private owners make it for themselves, so they only order it.
Stages of work using the "Warm seam" technology:
- The seam is unstitched (stitched if it is plastered);
- The seam is cleaned - often there is debris in it. We pulled boards, underwear, etc. out of the seams;
- If there is mold in the apartment, the seam is treated with mold poison;
- The seam is filled with polyurethane foam. The foam retains heat and prevents water from leaking inside the seam. In addition, foam fills all voids;
- Vilatherm is installed. It provides additional thermal insulation (but without foam the thermal insulation will be poor), as well as sound and vibration insulation;
- Next, a layer of sealant is applied, which must be at least 3 mm thick to ensure plasticity for years and protect the seams from water.
4. Sealing seams in a panel house: stages of implementation
Sealing of seams at home should be carried out taking into account the technology of applying sealant and the selection of high-quality materials.
Stages of work:
- cleaning the surface joint (from cement mortar, dirt, or old fillers);
- treating the joint with antimicrobial agents;
- filling the joint with heat-insulating sealant (filling all voids);
- Vilaterm tubular material, which is very elastic in nature, is laid on the uncured sealant;
- The final sealing process is covering the joint with mastic.
Considering the demand for the service, our works carry out sealing work all year round, regardless of weather conditions.
So, we see the use of polyurethane foam in the first described method, and sealant with insulation in the second. Polyurethane foam has one significant difference– thanks to it, the resistance of the structure to all kinds of external factors (including the effects of chemical components) becomes much higher. This type of foam can also absorb moisture in small quantities, and when it hardens, it turns into an excellent thermal insulator: apartment residents will forever forget about dampness and drafts, which is quite difficult to achieve using other sealing methods. In this case, however, the air circulation in the walls will stop, and the temperature in the apartment will rise by several degrees.
The industrial mountaineering company "Vertical" also carries out sealing of event seams in private cases. For example, to eliminate frost damage and leaks on balconies or loggias (corner, upper), external application of sealant is necessary. Or, if necessary: sealing double-glazed windows - removing gaps between the window opening and the double-glazed window frame on the facade side. These and other tasks can only be performed by industrial specialists.
5. Materials for sealing seams
To seal seams, we use only high-quality materials that we have been using for many years, the technology for working with which has been proven, and we know how they behave after 5-10 years.
Vilaterm
This is first of all thermal insulation material, as its name suggests, but also provides sound and vibration insulation. Manufactured specifically for sealing interpanel seams different diameters. It is selected for the seam - the diameter of the vilatherm should be one or two centimeters larger than the width of the seam, so that, on the one hand, it completely covers the seam, and on the other, it is not too flattened. Vilaterm is manufactured on modern equipment, environmentally friendly, made of polyethylene high pressure by foaming with a butane-propane mixture.
Akatamast
This is one of the best sealants Russian production, which fully complies with international standards.
Construction foam
We use professional construction foam. At negative temperature, we use Norwegian foam - there is nothing better in the cold. Its use allows us to work safely up to 15 degrees.
At positive temperatures, we most often use German professional foam.
6. Technology of insulation and sealing of interpanel seams “Warm seam plus”
When winter comes, many residents of panel houses have a question: how to keep the apartment warm? The most common cause of heat leakage is depressurization of the seams between panels. Eliminating it is the least expensive way to maintain the thermal balance in your apartment. The “Warm Seam Plus” technique will help you do this even without the use of heating devices.
To keep heat in the house, dozens of ways have been invented - from sealing window frames paper strips until special cords are driven into the cracks. However, homemade methods have been replaced by new technologies for sealing seams, which can protect against cold and drafts, as well as eliminate dampness and fungus with much greater efficiency.
The distinctive features of the technique make the warm seam system much more promising than the primary sealing technique. It is carried out in several stages: the leaking seam is filled with insulation, and then covered with mastic for complete waterproofing. Any mastic can be used: as on water based, and containing a hardener in its composition.
The standard “Warm seam” method involves the use of installation work special foam, as well as vilotherm and sealing mastic. This technique can be used for both secondary and primary sealing. A more complex method has the following sequence: when the interpanel seams are covered with a layer of mortar, due to which the Viloterm does not fill the seam, a hole with a diameter of 50 cm is drilled into it, into which polyurethane foam is blown.
We have described one of the most efficient systems heat saving for panel houses. In cases where even more is needed effective insulation, a three-component sealing system is used. Polyurethane foam is used here, which increases resistance to any impact, as well as standard insulation and sealant. After hardening, the foam becomes an excellent heat insulator, and the intra-seam space is completely filled.
7.
So, as I wrote above, mold in an apartment is very harmful to health. But what to do if it does appear?
If the mold has not spread much:
- First you need to eliminate the source of moisture - in 99% of cases this is interpanel seams. They need to be sealed and then the mold will dry out.
- Dry the walls. Attention! Under no circumstances should you warm up the room until the source of moisture is eliminated! This will only lead to mold starting to grow.
In parallel with the seam sealing work, our specialists will carry out comprehensive measures using special bactericidal materials that will completely remove mold from contaminated areas.
8. Typical defects in interpanel seams
Often, panel buildings acquire various defects during operation. The reason for this may be the deformation of the walls, causing leaks at the vertical joints of the panels. Sometimes leaks occur at the contact points wall panels And balcony slabs, at the joints window openings. In winter, joints not protected by insulation freeze, heat escapes through them, and the apartment becomes cold.
Sometimes defects in slabs are due to poor quality of the concrete from which they were made, or deviations during their creation from technological rules. Often a major influence on the formation of defects has harsh climate. To find out what condition the slabs are in, thermal imaging testing is used. Looking at images made using it, you can see typical defects slabs
9. Do-it-yourself sealing of interpanel seams
It is not necessary to contact specialists to seal panels in a residential building, especially if your apartment is on the ground floor.
You will need the following tools and materials:
- round or staircase;
- 1-2 buckets of mastic;
- Viloterm and mounting foam "Macroflex";
- metal spatula 10 cm wide;
- a rubber spatula with which you will level the mastic in the seam;
- knife with which you will cut the vilotherm.
You need to choose the type of sealing that is most suitable for the building. During primary sealing (carried out during the construction of a building), the seams between the panels are filled with special foam, insulation is laid on it, and the resulting seam is sealed with mastic.
Secondary sealing is carried out using two methods: with or without opening the seam. The second method involves applying a new layer of waterproof compound on top of the existing one. Before this, the area is thoroughly cleaned of dirt. The first method involves complete removal of the old sealant, and if necessary, the edges of the panels are cleaned where peeling has occurred. All existing cracks and voids are filled with foam, covered with insulation and coated with mastic. One of the main conditions for a high-quality sealing is to ensure that the joints are clean and dry before applying the final layer of sealant. Sealing the external seams of a panel house is a very important task and must be done very carefully.
Insulation of interpanel seams in reality cannot be done at an average daily temperature below 5 degrees Celsius. Also, work is not carried out in wet snow, rain or on a wet panel. Strong wind is also unacceptable.
Sealing seams falls into the category of high-altitude work, therefore each of our specialists has a special permit, and also regularly undergoes retraining and advanced training courses. Our company has the necessary permit and license to carry out work at height, as well as special equipment that ensures high-quality and safe work.
If necessary, we use scaffolding. For example, with their help you can reach places that are not suitable for work using the industrial mountaineering method. For small volumes of work in such places, an aerial platform or a high-rise cradle is sometimes used. Most the best way will be selected after experts determine approximate cost and scope of work.
