1. Adhesive composition for laying blocks ofcellular aerated concreteK21/1

2. Adhesive composition for laying blocks ofcellular aerated concretewinter K21/2(with antifreeze additive)

DESCRIPTION

The adhesive composition for laying blocks of cellular aerated concrete is a dry building mixture consisting of cement, natural quartz sand, mineral fillers and polymer additives. When mixed with water, it forms a plastic mortar mixture. Thanks to special water-retaining additives, the adhesive mixture provides excellent adhesion of the blocks even when applied in a very thin layer, which significantly reduces consumption. After hardening, it forms a durable waterproof and frost-resistant solution.

APPLICATION AREA

The adhesive mixture is intended for laying blocks of cellular aerated concrete with strictly maintained geometric dimensions and shape (dimensional tolerance ± 1–2 mm). The properties of the material make it possible to lay blocks with a small seam thickness (2-3 mm), to obtain a wall that is homogeneous in terms of thermal insulation and to prevent its freezing through the seams. The adhesive composition is also suitable for laying expanded clay concrete blocks and other piece wall materials, eliminating defects (irregularities, potholes, chips) in them. Used both inside and outside buildings.

BENEFITS

- suitable for indoor and outdoor use;

- reduces heat loss through the building envelope;

– high compressive strength;

- convenience and ease of use;

– waterproof;

- frost-resistant;

– has a high adhesion strength to the cellular concrete base;

- cost-effectiveness, the ability to perform masonry with a minimum thickness of the seam;

- environmentally friendly.

SURFACE PREPARATION

All surfaces on which the adhesive composition is applied must have a temperature of +5 to +25°C. The base must be even, strong, clean, free of dirt, dust, ice, oil stains, paint, particles that can impair the adhesion of the adhesive to the base. Loose and fragile areas of the surface must be removed. The surface of the blocks before applying the adhesive composition should be moistened with a small amount of water.

PREPARATION OF THE ADHESIVE COMPOSITION

Pour the dry mixture gradually into a container with water (water temperature from +10 to +25 ° C) at the rate of 0.22–0.26 l of water per 1 kg of dry mixture (5.5–6.5 l of water per 25 kg bag ). Stir the mixture with a low-speed (up to 300 rpm) drill-mixer or manually until a homogeneous, lump-free consistency. Set aside for 8-10 minutes to ripen the mixture, then mix thoroughly again. Properly prepared adhesive composition should have the consistency of thick sour cream, while the profile formed when the adhesive composition is applied to the contact surface with a notched trowel should not blur. In the process of conducting work, it is necessary to mix the finished solution from time to time to maintain the uniformity of its consistency. Adding water to the prepared adhesive to restore its consistency is not allowed. The solution retains its properties for 90–120 minutes (depending on air temperature). In winter, the use of the solution is limited to 30 minutes.

PERFORMANCE OF WORK

The masonry process is to be carried out in compliance with the technology of masonry element manufacturers and building codes. The finished adhesive composition is applied with a special tool (a box with a comb, a toothed bucket), corresponding to the width of the blocks. It is allowed to apply the adhesive composition on the contact surface with a steel spatula or trowel, leveling with a notched trowel. To apply the adhesive, it is recommended to use a notched trowel with a tooth size of 5 mm. The blocks are placed on an evenly distributed mortar mixture and their position is corrected with a rubber mallet within 5 minutes after laying. Excess mortar squeezed out of the seams is not overwritten, but removed with a trowel. The recommended thickness of the adhesive solution between the blocks after pressing should be 2–3 mm. With this method of laying, the total area of ​​​​cold bridges is maximally reduced. The minimum consumption of the mixture is achieved as a result of the installation of blocks with the correct geometry. The approximate consumption of the mixture is 1.6 ... 1.8 kg / m² / mm (about 25 kg per 1 m³ of blocks). Works should be carried out in dry conditions, at an air temperature of +5 to +25°C. Protect the finished masonry from the weather with a construction film for a period of at least 24 hours. After completing the work, thoroughly rinse the tool with water. Water used to clean the tool must not be used to prepare a new portion of the adhesive.

PRECAUTIONS

The material contains Portland cement and silica sand, which can cause eye and skin irritation. The use of personal protective equipment is strongly recommended to protect against contact with the mixture in the respiratory tract, eyes and skin. If mixture comes into contact with skin, rinse with water. If adhesive gets into eyes, rinse thoroughly with clean water and seek medical attention immediately. Avoid breathing dust. Keep out of the reach of children.

TECHNICAL INDICATORS AND CHARACTERISTICS

The specified parameters are valid at an air temperature of 20°C and a relative humidity of 60%. In real construction conditions, deviations are possible depending on working methods and temperature and humidity characteristics.

PACKAGING, STORAGE AND TRANSPORTATION

The adhesive composition is packaged in bags of 25 kg. On a pallet 1m × 1.2m - 1000 kg (40 bags). Shelf life in original undamaged packaging in a dry place at a temperature of +5 to +25°C - 12 months from the date of manufacture. When transporting in open transport, protect from atmospheric precipitation.

ADHESIVE COMPOSITION FOR LAYING BLOCKS FROM CELLULAR AERATED CONCRETE WINTER K21/2 (WITH P/M ADDITIVE)

In winter conditions, when the air temperature is below +5°C, it is necessary to use winter adhesives, to which special antifreeze additives are added. Designed for use in winter conditions down to minus 10°С. Bags with such mixtures are marked with a special marking.

- the time of use of the heated mixture is 30 minutes;

- the blocks used in the masonry should not be frozen, snowy or wet;

- it is desirable to preheat the blocks at least to a temperature of + 1 ° С.

ATTENTION

The given information determines the scope of the material and the method of carrying out the work, but at the same time it cannot replace the appropriate training of the performer of the work. Current building regulations must be followed. The manufacturer is not responsible for the misuse of the material, as well as for its use for purposes and conditions not provided for by the instructions.

Gas silicate blocks are widely used. The motives are clear: the low price of the material, the high speed of erection of structures, as well as the relatively low weight, which in turn makes it possible to abandon deep foundations.

However, gas silicate itself is a porous material, which makes it colder and reduces the thermal efficiency of the building. The heat escapes through many small holes in the block. It is these features that should be considered when choosing a masonry adhesive.

For gas silicate blocks, glue based on sand, cement, plasticizers of organic and mineral origin is used. The thickness of the seams and the consumption of glue will depend on the manufacturer and the elements included in the glue.

Composition and properties of adhesive for gas silicate blocks

The composition of the adhesive for gas silicate blocks necessarily includes:

• fine-grained sand;
• binding base in the form of high-quality Portland cement;
• modifying inclusions.

Polymer additives provide plasticity and adhesive properties of the solution. The modifying inclusions keep internal moisture that protects seams. The solution provides high adhesion of blocks, is not absorbed by them and reduces their thermal conductivity.

Such properties of the composition are among the main features of the adhesive for gas silicate.

What glue is best for gas silicate blocks

• Manufacturer. Well-known suppliers value their reputation and carefully monitor the quality of their products.
• Storage and packaging. An important condition for glue is a dry, ventilated room. If you are not sure how exactly to store the product or if the packaging is damaged, it is better to refuse this. Also, experts do not recommend taking a dry mix by weight.
• Advance paynemt. Before buying glue for gas silicate blocks, it is recommended to make a preliminary calculation of the consumption of materials, which will allow you to more accurately determine your needs and save money by not allowing you to buy too much.

Pros and cons of gas silicate glue

The advantages of glue for laying blocks include:

• increased level of adhesion;
• resistance to low temperatures and moisture;
• the adhesive composition does not shrink, and also has a high setting speed.

It should also be noted that the products are of interest to the final budget cost. Although the adhesive mortar costs twice as much as a conventional cement mortar, the consumption of glue is 4-5 times less (the mortar is applied with a minimum thickness of 2-3 cm).

It also has its advantages:

• increase in the strength of the structure;
• increase in thermal insulation;
• due to the small thickness of the seams, the laying of gas silicate blocks is smooth and beautiful.

The disadvantages of gas silicate glue include increased requirements for evenness and the treated surface.

Comments:

Adhesive is used for gas silicate blocks when laying walls erected using gas silicate and foam concrete blocks, as well as brick slabs.

Glue for gas silicate blocks has a number of advantages: plastic, withstands low temperatures, repels moisture.

Properties and technology of use

In finished form, the masonry adhesive looks like a viscous monotonous mass. Its basis is cement. Various additives give it the properties of plasticity, retain moisture and push out small air bubbles from the mixture. Thanks to the components included in the composition, the glue protects.

Universal adhesive for gas silicate blocks contains a mandatory ingredient that prevents the blocks from absorbing moisture from the adhesive mixture. At the same time, the additive retains moisture in the adhesive solution and allows you to securely fasten the blocks.

For thorough mixing, you must use a construction mixer.

By improving the composition, additives increase the strength, frost resistance, and water resistance of the solution.

Manufacturers produce glue for gas silicate blocks:

• usual;
• frost-resistant.

To work at low temperatures (-5-15 ° C), a ready-made composition with additives resistant to low temperatures is purchased or a special component is added to the usual one.

To dilute the adhesive mixture, 2-2.4 liters of any water will be required per 10 kg of dry weight.

Pour water into the container, then pour out the measured amount. Mix using a construction mixer (drill with a special nozzle).

The solution is infused for 10-15 minutes, mixed again. The prepared composition must be used within 2 hours.

A prerequisite for a high-quality adhesive mixture is the addition of dry ingredients to water, and not vice versa.

Care must be taken when mixing. The dry mix contains cement. When preparing and styling, it is advisable to use a mask and gloves to protect the skin and lungs.

Laying technology

The base must be cleaned of dust, paint, stains of grease, bitumen.

To apply the adhesive, you can use a notched trowel or bucket trowel.

The first row of blocks is laid out on the foundation, which is fastened with a traditional cement mortar. This must be done in order to even out the initial row, the thickness of the seam between the bricks can vary and reach several cm.

The second and subsequent rows are laid on the glue for gas silicate. If the ambient temperature is more than 30°C, it is necessary to moisten the bricks before applying the mortar.

The adhesive mass is applied and distributed on the prepared surface with a notched trowel. A special bucket trowel will help to apply the solution vertically.

Within 15 minutes, the masonry is leveled with a rubber mallet. Remove excess solution.

The glue dries within 24 hours. The highest degree of strength of the lined wall occurs after 3 days.

Not only a bricklayer, but a non-professional with skillful hands can build walls and partitions. To do this, it is enough to carefully observe the technology of laying gas silicate blocks.

Pros and cons of glue

The adhesive used for gas silicate blocks has distinctive advantages compared to conventional cement-sand mortar.

Easily diluted, consists of only two components for mixing - water and dry mix. Does not need large containers for cooking, such as a concrete mixer. Less time and labor is required to prepare the adhesive.

There is no need to store a large number of components - sand and cement. Economical - the thickness of the seam according to the norm is 3 mm. Due to the additives, it is plastic, non-combustible material, does not create conditions for the appearance of mold.

It is used when laying up to -5°С, frost-resistant mixtures - up to -15°С. The possibility of leveling the masonry within 10-15 minutes. A thin seam gives excellent thermal insulation. Dry building mix is ​​stored for a long time.

Can be used for bonding various surfaces. Easy to apply and remove excess. When breeding, it allows you to avoid debris and dirt, which is convenient for the construction of partitions, redevelopment of walls in the apartment.

Glue for gas silicate has one significant disadvantage. It is not used if the sizes of the bricks differ and it is necessary to lay out seams of various thicknesses.

Additionally, block adhesive can be used for leveling porous surfaces, for waterproofing walls, when laying tiles on a cement plaster or brick base.

Glue is bought from the following calculation: for a layer thickness of 2 mm, 3 kg of dry mixture is needed for every 1 m².

The adhesive consumption depends on:

• installer experience;
• laying quality;
• the quality of the blocks themselves (how smooth the surface they form).

The building materials market is now developing rapidly, constantly replenishing with new and new commercial products. Each of them has its own characteristics, improved quality and improved structure. So, for example, if earlier the walls of the house were built of bricks laid on a heavy cement mortar, and created huge loads on the foundation, now everything is different. From lightweight block elements, you can build a durable dwelling by gluing them together with an adhesive solution. This article will tell you about what constitutes glue for laying gas silicate blocks or other types of block structures.

Types of blocks used

The construction of a new architectural object invariably entails the choice of the necessary building materials. For a long period of time, brick remained the main element of construction, but now it is used less and less. The main reason for this is the complexity of laying bricks. In addition, the price of ceramic analogues of bricks is significantly higher compared to the cost of glue for foam blocks.

Building blocks, presented in a wide variety on the construction market, have become a worthy replacement for bricks today. Their main varieties are as follows:

1. Expanded clay blocks. The material has several advantages. It successfully combines qualities such as high strength and low weight. The use of blocks implies a small waste of time to create a solid masonry. Expanded clay concrete block elements allow you to build buildings up to 3 floors high manually, without the use of special equipment.
2. concrete blocks. In the construction of residential buildings, this material is rarely used, since it is characterized by poor thermal insulation properties. However, their frost resistance and strength allow builders to use the material for the construction of buildings of economic importance.
3. gas silicate blocks. In the construction environment, they are also known as cellular concrete. The advantage of their use is due to significant cost savings. The small dimensions of the gas silicate block save usable space.
4. Polystyrene concrete blocks. When they are created, a special substance is added to the usual concrete solution, which helps to make the material frost-resistant, has good sound-proofing properties, and is durable. The low price of polystyrene concrete blocks makes the final cost of construction low. Polystyrene concrete blocks are used both in private and industrial construction.
5. Foam concrete blocks. When conducting construction using foam concrete blocks, there is no need to use special equipment if the height of the building does not exceed 3 floors. Foam concrete blocks find their application in the construction of cottages. Their main advantages include environmental safety.

Types of glue for laying blocks

Adhesive for foam concrete and other types of block structures is gaining popularity year after year. In the construction industry, it is used more and more often, and the demand for the material is due to many undeniable advantages. First of all, of course, there is a reduction in labor costs, because there is no need to knead the mortar based on cement, strictly observe the proportionality of the components, etc. And the question of how to calculate the amount of glue for foam blocks is solved faster and easier.

The basis of any adhesive composition is a cement-sand mixture, as well as a variety of polymer additives with the properties of structure formation, moisture retention and plasticization. It is not possible to prepare such a solution with your own hands, but manufacturers set a very affordable price for products of this kind in the range of 150-550 rubles for one bag weighing 25 kg. With a reasonable consumption of material for laying 30 blocks with standard parameters (600 * 200 * 300), one bag of dry adhesive mass is taken.

A large number of building blocks have now been invented, and each variety requires its own adhesive composition with certain properties.

For foam blocks

Glue for foam blocks is a special mixture based on cement and sand, and the structure of these materials is somewhat different from that of the bulk composition used to prepare the classic cement mortar. Among the components of the adhesive for blocks is quartz sand, crushed to the smallest fraction.

Advice! Prepare the adhesive mixture for blocks with the calculation of its production within 2-2.5 hours. After this time, the solution begins to thicken rapidly, losing its original properties. Adding water will not correct the situation, leading to a deterioration in the characteristics of the adhesive.

After applying the adhesive composition, its thickness is minimal due to the absence of coarse-grained components. In addition, the mortar quickly gains strength due to the use of high-quality Portland cement in its composition. When laying the foam block on glue or a solution with an adhesive base, you should know that this material consists of a whole range of additives that significantly improve its technical characteristics. Among these components, there are compounds that retain moisture, increase the moisture resistance of block masonry and prevent the formation of mold fungi. The presence of special additives in the adhesive mortar gives the joints between the blocks greater plasticity than that of a conventional cement mortar.

Such a property as plasticity reduces the likelihood of deformations in the masonry, the appearance of cracks in it, distortions and cracks in the wall of blocks. The inclusion of auxiliary additives in the adhesive composition by manufacturers makes it possible to obtain frost-resistant adhesive for foam blocks. Its main advantage lies in the fact that winter glue for foam blocks allows installation work even at low temperatures down to -15 ºC.

For ceramic blocks

The use of ceramic blocks for the construction of buildings has recently become more in demand. Ceramic blocks look like bricks, but inside they have a void. They are made from baked clay, and the dimensions of such building material are significantly larger than those of ordinary bricks. Due to the internal emptiness, the thermal conductivity of the material decreases, and the thermal insulation properties, on the contrary, increase.

In order for the laying of ceramic blocks to be perfect, experts recommend using a special glue. Such a solution helps to create seams with a thickness of only 2 mm. The composition of the adhesive in its structure, thermal conductivity and density is similar to ceramics, which makes it possible to form a uniform heat-insulating plane.

Glue for ceramic blocks is made from a cement-sand mixture with additives in the form of imported plasticizers. These components are made from organic and mineral raw materials, and are characterized by water-repellent properties.

For polystyrene concrete blocks

Polystyrene concrete blocks are among the building materials made of lightweight concrete. They contain mineral compounds of organic origin. The main components of the adhesive solution are water, Portland cement and additives, including small expanded polystyrene granules with a porous structure.

The unique combination of various useful components in the adhesive endows the finished walls with such characteristics as good water repellency, good thermal insulation properties, rot resistance, good load-bearing capacity, transferred to the finished walls. Such an adhesive composition is sold in the form of a dry mixture, and requires mixing the powder with water and thorough mixing before use.

For gas silicate blocks

Glue for cellular blocks, which has another name - gas silicate, is represented in stores by various brands that represent different manufacturers. Prices for glue for gas silicate blocks vary between 115-280 rubles, but this cost does not always indicate the good quality of the adhesive composition. Sometimes the consumer has to overpay money only for a promoted brand. In order not to make a mistake, construction experts advise purchasing from the manufacturer not only the glue itself, but also the building blocks of the desired variety. According to statistics, the use of gas silicate blocks helps to reduce the total cost of construction by about 40%.

Glue for gas silicate blocks has several useful advantages, namely:

• Small cost. The consumption of glue for gas silicate blocks is about 6 times lower compared to a cement-sand mortar, and the cost is only twice as much.
• The resistance of the composition to the effects of precipitation (snow, wind, rain).
• No cold bridges. Interlayers are not formed in the material, characterized by a high level of thermal conductivity, provoking a decrease in the uniformity of the block masonry.
• High strength. If we compare the adhesive for gas silicate blocks with the cement-sand mortar mentioned above, then it helps to form masonry from blocks of greater strength.

When choosing glue for a gas block, you should pay attention to its composition and technical characteristics, because such information will help to get an accurate picture of what components the solution is made of.

This is interesting! Frost-resistant adhesive for gas silicate blocks consists of special substances that allow it to be used even at low temperatures (-15 ºC, and sometimes even -25 ºC) outdoors.

Information about the size of the fraction of bulk materials that make up the solution will be useful, at what temperatures the manufacturer recommends using the product, what should be the recommended layer thickness. It is also worth paying attention to the label, which displays useful data on the period of hardening of the adhesive solution, the amount of adhesive used in the course of work, etc.

Universal glue

Universal adhesive for blocks of different brands and types allows the consumer to purchase a high-quality dry adhesive mixture at a favorable cost, which can later be used both for gluing foam block elements and for fixing aerated concrete, ceramic, polystyrene concrete blocks with each other. Among the most famous universal adhesives for building blocks are TM Knauf and Varmit adhesives. They are designed to work in winter and summer periods of the year, are made from environmentally friendly components, frost resistance, moisture resistance and economy.

How to calculate how much glue you need

The consumption of glue when laying walls from foam blocks depends on several factors. The type of the block element is important in the calculations. For example, for a cellular block of glue, more will be needed, since the material is porous, which means it absorbs moisture well. Also, the consumption level depends on the brand and manufacturer of the adhesive composition.

In general, the consumption of any type of adhesive for blocks is more economical than a conventional solution of sand and cement. Laying blocks with its use is obtained with thin seams, respectively, and the consumption of the composition is reduced by about 6 times. The use of such modern material as glue for blocks makes it possible to achieve a seam with a maximum thickness of 5 mm, and with the observance of laying technologies - only 2 mm or even 1 mm. A small seam prevents the development of cold bridges in the walls, and the consequences associated with this unpleasant phenomenon - the appearance of fungus and dampness.

The geometry of the blocks themselves also has a certain influence on the consumption of glue. If the building material is uneven, then the adhesive solution for its installation will need more.

To minimize mortar costs, it is important to determine how much glue is needed for laying a cube of foam blocks. Knowing this information, as well as the exact number of block elements, you can easily calculate the amount of dry glue required for construction. According to the standards established in construction, the consumption of glue for aerated concrete per 1 m 3 is no more than 1.6 kg, subject to a thin seam of 1 mm. However, this condition is met only with a perfectly flat surface. Sometimes up to 30 kg of dry adhesive is used per 1 m 3 of building material. On average, per 1 cubic meter. gas blocks have to waste 1 bag of adhesive weighing 25 kg. But this is only from the point of view of theory. Often, waste is 1.5 packs of dry matter, or 37 kg. There are several reasons for this:

• You need to know exactly how to lay gas silicate blocks or block structures made of aerated concrete. The experience of the master performing the masonry has a great influence on the quality of performance.
• Surface irregularities increase the consumption of glue for blocks.
• The number of layers of the adhesive solution affects its consumption.
• The weather in which the laying of building blocks is carried out.
• The number of rows formed by laying block structures.

Being interested in what kind of glue consumption for aerated concrete blocks is optimal, you should be aware that it will be less when using a fine-grained composition. In this case, the masonry turns out to be thin and as close as possible to the recommended parameters.

Manufacturers of adhesive solutions give various recommendations on what should be the consumption of glue for foam blocks 20 * 30 * 60.

They concern not only breeding, but also the laying of the composition, as well as the formation of block masonry with its help:

1. First of all, read the instructions from the manufacturer's company before starting to mix the adhesive solution from the dry mass.
2. Adhere to the technology for preparing the composition, then the material consumption will be less, respectively, and the cost of foam block glue will be reduced.
3. When laying foam blocks on the prepared adhesive, observe the temperature regime required by the manufacturer.
4. To maintain the uniformity of the composition, periodically mix it during the laying of blocks.
5. When self-laying blocks on glue and lacking proper experience from the master, it is better to purchase all the materials with a margin.
6. Applying glue with a notched trowel to the surface of the block, you can reduce the consumption of the mixture by an average of 25-30%.
7. It is better to prepare glue from dry mass in a warm room, and then deliver it to the place where the walls from the blocks are erected.

The right choice and use of glue for blocks allows you to build a high-quality and durable home, with good thermal insulation properties.

To finish the facades of buildings in modern construction, special blocks made of modern materials are increasingly being used. They have good technical characteristics, look great, are relatively inexpensive and very easy to use. For fastening, glue for gas silicate blocks is used, which fully complies with all current safety standards.

Lightweight blocks made of modern materials, thanks to their special structure, retain heat well inside the building. And in order not to worsen this property, for installation it is necessary to use not an ordinary solution, but a special mixture. Therefore, many are interested in the question, which glue for gas silicate blocks is better?

It is very difficult to give an unequivocal answer, since there is no separate brand on the market that would surpass all competitors in all respects. Each situation requires its own approach, so first of all, you need to pay attention to the technical characteristics of the adhesive and be guided by the operating conditions of the building, the climatic zone, and the average annual level of air humidity.

Types and composition of glue

There are several types of glue:

• - mixture for masonry indoors;
• - mix for a laying outside of rooms;
• - mixture for masonry indoors and outdoors;
• - a mixture for laying over underfloor heating with a special enhanced thermal conductivity and resistance to temperature effects;
• - a mixture for masonry in places with high humidity and for finishing pools. Possesses high resistance to influence of moisture;
• - universal mix with the increased speed of hardening.

All of these varieties are present on the building materials market in unlimited quantities. The price of glue for gas silicate blocks depends on the country of origin and technical characteristics. In general, it is accessible to most ordinary Russians. When making a large wholesale purchase, you can save a decent amount, so it is important to correctly calculate the amount of materials needed for repairs so that during the work you do not have to buy the missing amount.

The more versatile properties the adhesive has, the more expensive it will cost. But you can not save on building materials. A small gain now will lead to a huge loss in the future. Any repair is carried out with a long-term perspective, which means that the materials used must be of the highest quality and durable. This is the only way to solve the issue of housing decoration for many years to come.

The composition of the adhesive includes fractionated sand, Portland cement and special chemical compounds that are responsible for the properties. Moreover, all elements are non-toxic and absolutely safe for humans. During operation, they also do not react and do not create new compounds, which has a positive effect on the durability of the masonry. The preparation of the working solution is no different from the standard procedure. Simply add the required amount of dry mixture to a container with water and mix thoroughly until a homogeneous mass is formed.

Features of working with glue

The work is carried out using a conventional trowel or spatula. The laying of gas silicate blocks on the glue is carried out sequentially in a pre-selected direction. The master simply moves from one corner of the room to another, gradually covering the entire treated area. The blocks are pressed against each other as tightly as possible so that no seams are visible. The width of the adhesive layer should be 2-15 mm depending on the situation. Excess solution is removed from the surface with a damp cloth.

The glue dries depending on atmospheric conditions in 2-24 hours. It will take 7-10 days for it to gain its maximum density, so it is better not to perform any manipulations with the treated surface for the first time after repair. The consumption of glue is approximately 15-20 kilograms per cubic meter. There is no need to add additional additives to the solution, the dry mixture already contains everything you need for use.

The surface to be treated is pre-prepared for repair. To do this, it is leveled and primed. You can also carry out antifungal treatment with a special liquid. You can work with glue at temperatures from -8 to +30 degrees Celsius. The lower value is typical for winter, frost-resistant glue for gas silicate blocks. It may differ for other models.

Useful tips from professionals:

1. The tools used in the work must be made of medium hardness metal alloys resistant to corrosion.
2. At high ambient temperatures and low air humidity, it is necessary to prime the surface to be treated immediately before laying. This will increase the level of adhesion of the solution to the walls.
3. It is necessary to carry out work in protective gloves and special glasses. If the composition gets into the eyes, you should immediately consult a doctor.
4. Do not store the dry mix for a long time in high humidity conditions, as this can make it unsuitable for work.

Working with glue is no more difficult than with the usual cement mortar. You just need to follow the manufacturer's recommendations, and then everything will turn out without any problems. The main thing is to always remember about safety and not to work without protective accessories, so that ordinary repairs do not turn into unnecessary sick leave.
