Overview of adhesive mixtures for laying aerated concrete blocks. Adhesive for gas silicate blocks The best adhesive for laying silicate blocks

Glue for gas silicate blocks is a dry cement-sand powder with the addition of organic and mineral plasticizers. It is produced, as a rule, in packs of 25 kg. It is used in the construction of external and internal walls.

Glue is characterized by a lot of advantages:

High heat-saving properties. Its use minimizes the risk of "cold bridges".
Strength, which is much higher than that of a cement-sand mixture.
Resistant to weather conditions.
plasticity.
The ability to create a thin seam that increases the quality and appearance of the masonry.
Ease of mixing.
Financial benefit. The cost of the cement mixture is 2-3 times lower, but its costs are almost 6 times higher.

The composition of the adhesive includes special additives that prevent rapid drying. This allows you to tightly connect adjacent blocks, and the hitch will not lose strength for many years. The setting period of the solution is 3-4 hours, and the time during which the position of the block can be corrected is 10-15 minutes.

Glue for gas silicate blocks: features of choice

When choosing an adhesive for gas silicate, it is necessary to pay attention to several factors:

Best before date. "Expired" or improperly stored gas silicate adhesive loses the main part of its bonding properties.
Manufacturer. Do not chase a small cost and buy glue from little-known companies. It is better not to risk the reliability of your home and buy goods from a well-established manufacturer.
Weather. If the laying of gas silicate blocks will occur at temperatures below +5 ° C, then frost-resistant compounds are used.
Consumption. Before you buy gas silicate glue, you need to clarify its consumption per 1 m3. On average, it takes about 6 liters of water to knead 25 kg. In this case, the weight of the finished solution from 1 bag will be 30-31 kg. Several factors affect the total consumption of glue (layer thickness, characteristics, manufacturer), but on average it is 15-40 kg per 1 cubic meter of masonry.
Scope of work. A preliminary calculation will help not to make a mistake when buying and sometimes save a lot. Large lots are usually sold at an impressive discount, which will positively affect the overall construction costs.

Glue consumption directly depends on the quality of gas silicate blocks. If you use a material with a perfectly flat surface, then about 20 kg of the mixture will go to 1 cube of masonry (with a 2 mm joint thickness). If the blocks have shape defects, then the glue will have to be spent more. Experts advise to purchase a mixture with some margin.

The most common brands of glue

Many domestic and foreign companies are engaged in the production of glue for gas silicate. Depending on the quality of the additives, winter and summer types are distinguished. Frost-resistant glue is recommended for use at low temperatures (from +5 to -10 °C). Packages have a standard weight (25 kg), but are decorated with a special logo (snowflake).

Experienced craftsmen offer several compositions that have shown themselves well in the construction market.

	Glue consumption per 1 m3, kg	Benefits and application features	Cost 25 kg, rubles
		Frost resistance
		Distinguish between winter and summer options	245 simple and more than 300 - frost-resistant
"Prestige"		Differs in high cold resistance, ecological purity and speed of preparation
"Bonolith"		Non-toxic and good frost resistance
"Etalon-Teplit"		Available in plain and frost-resistant versions
		Versatility
"Zabudova"		Frost resistance and ease of application
		Summer version with excellent water repellency

As you can see, the price of a good gas silicate adhesive cannot be too low. Attempts to save money threaten future problems with the quality of masonry.

Glue preparation

When preparing a mixture for laying blocks of gas silicate, several rules should be considered:

The container for diluting the glue must be clean, durable and dry. An ordinary plastic bucket can be a good option.
During the mixing process, the mixture is added to the liquid (never vice versa).
Pour the solution in small portions.
For work it is better to use a drill with a special nozzle (mixer).

The density of the finished glue should resemble sour cream. It can be applied at any time of the year, but it is better if the temperature is above -15°C.

Glue preparation takes place in two “runs” with a 5-7-minute interval. Approximately 200 g of water is consumed per 1 kg of the mixture (the exact proportions should be indicated on the package). An overdose of liquid threatens to deteriorate the adhesive characteristics. In this case, the consumption of finished gas silicate glue will be at least 10 kg per 1 m3. Do not dilute too much solution at a time. The resulting adhesive does not lose its properties within 80-120 minutes (in winter - within half an hour), after which it hardens and becomes unsuitable for the installation of gas silicate blocks.

Features of masonry blocks

The work surface needs preliminary preparation. Firstly, it must be cleaned of foreign objects and debris, remove paint, oil, dust and soot residues. Secondly, it must be strong and dry. If the surface has a glossy appearance, then it should be sanded to a matte state. Smooth out irregularities and depressions (you can use already prepared glue).

Work Guide

After preparing the surface, you can proceed to the installation of walls. A smooth grater (trowel) is used to apply gas silicate glue, and a notched trowel is used for leveling. The mixture must be applied both to the bottom row of masonry and to the side of the block to be installed.

Approximately 20 minutes should elapse between applying the solution and further work. The new block must be lightly pressed to the base and besieged with a rubber mallet. The hardening of the mixture will begin in about 10 minutes, during which it is possible to correct possible irregularities in the masonry. In the warm season, the glue dries out in 1-2 days, and reaches its final strength at the end of 3 days.

The air temperature in the room has a significant effect on the speed and quality of solidification. With cold weather, the setting time of the glue increases, with warming, it decreases. Too high temperatures can cause shrinkage cracks.

1. When choosing a mixture, it is better to focus on options that even a novice bricklayer can handle (for example, Etalon-Teplit glue or CM 999). Expensive solutions require more professionalism.

2. The second and subsequent rows of blocks are “planted” on the glue. Installation of the first tier occurs only on cement mortar. This helps to smooth out the likely unevenness of the foundation and improve the quality of the masonry.

3. The mixture should be applied in a thin layer (2-3 mm). Otherwise, the material consumption will increase several times, which will negatively affect both the quality of the seams and the overall construction budget.

At first glance, laying blocks on gas silicate glue is a simple procedure. This is not entirely true: the correct use of the adhesive composition is not within the power of every master. In this regard, it is desirable that the installation process is carried out only by a qualified bricklayer who can guarantee the high quality of the masonry.

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:

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.
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.
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.
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.
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 that have 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.

It 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 cost-effectiveness.

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:

First of all, read the instructions from the manufacturer's company before starting to mix the adhesive solution from the dry mass.
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.
When laying foam blocks on the prepared adhesive, observe the temperature regime required by the manufacturer.
To maintain the uniformity of the composition, periodically mix it during the laying of blocks.
When self-laying blocks on glue and lacking proper experience from the master, it is better to purchase all the materials with a margin.
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%.
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.

As the practice of recent years has shown, the use of dry building mixes in most construction and repair work is much more profitable than using a conventional mortar. So, with the help of glue for foam concrete, you can not only perform masonry much faster and better than before, but also save money at the same time. After all, the consumption of glue for gas silicate blocks is several times less than that of a conventional mortar.

The company "Osnova" offers glue for gas silicate blocks of its own production in a wide range. The use of modern equipment and advanced technologies allows us to produce world-class products that have passed all the necessary checks and have the appropriate certificates.

At the same time, we offer to buy high-quality foam concrete adhesive, the price of which is noticeably lower than the average market price.

Advantages of using glue for gas silicate (aerated concrete) blocks

The use of a special adhesive for foam concrete is almost always more profitable than a conventional cement-sand mixture, for the following reasons:

glue has better adhesion, which helps to increase the strength of the structure;
it is easy and convenient to work with him;
adhesive for foam concrete has an optimal setting time;
has high frost resistance and moisture resistance;
consumption of glue for gas silicate blocks is several times less than cement mortar;
the adhesive is resistant to temperature fluctuations and tolerates both high and low temperatures equally well;
the level of thermal insulation of the building is increased.

Calculation of glue consumption for aerated concrete blocks

Before starting work, it is advisable to calculate the amount of materials needed in order to estimate the approximate cost of construction. Having a house plan, it is easy to determine how many blocks you need, since their geometric dimensions are well known. But how in this case to calculate the consumption of glue for gas silicate blocks?

In fact, everything here is quite simple. The consumption of glue, as a rule, is 15-20 kg per cubic meter of masonry, if the thickness of the adhesive layer is the recommended 2 mm. Therefore, knowing the number of cubic meters of block required for construction, it is not difficult to calculate how much foam concrete glue you need to purchase.

Glue is a mixture of substances that allows you to reliably adhere materials to each other. And in order for the seam to be strong and durable, a quality product should be used. To fix the gas silicate blocks, you need a special glue. Such a composition usually contains sand, cement, as well as organic and mineral plasticizers.

Currently, a wide range of products is presented in trade for working with gas silicate blocks. The result of the selection of such a composition is influenced by the preferences of the master and the conditions for the laying work.

What to choose a mixture for laying blocks

To recognize which glue for gas silicate is the best, it is worth considering customer reviews who have already managed to test the material on their own experience. Let us dwell in detail on the brands of glue that have gained the greatest popularity.

"Zabudova"

This mixture is great for mounting blocks in the winter. This is possible thanks to the ingredients included in it. There is a special additive that is not affected even by severe frost (frost-resistant). Most builders speak positively about the product, because it has such advantages as ease of application and elementary use. In addition, Zabudov's glue is inexpensive, which provides it with a leading position among all ready-made dry adhesives.

"Prestige"

This mixture is also not afraid of frost. It is used for laying blocks of cellular concrete, as well as slabs. A characteristic advantage of the glue is the speed of its preparation. In terms of economy, this composition is slightly inferior to the first, since its cost is slightly higher.

Bonolit

Such a composition for a gas silicate block can be used both in summer and in winter. Its main advantage lies in environmental friendliness. The glue does not contain unwanted impurities and toxins, absolutely does not pose any danger to human health. Perhaps this affects its cost, because it is more expensive than the options considered earlier.

Today, this building composition is actively used in the laying of gas silicate structures. The reputation of the adhesive is won by its positive properties:

The excellent thermal insulation characteristics of the mixture make it as similar as possible to cellular concrete. This will forever forget about frozen walls and heat leakage through the joints in the masonry.
The composition does not lose its properties even in direct contact with water, as well as the influence of very low temperatures.
The mixed solution is characterized by excellent plasticity, which makes its use comfortable.
The mixture is completely environmentally friendly. There is no release of toxic substances, since the product does not contain harmful impurities.
The composition is more expensive than previous products, and this is due to its qualities.

Aeroc

Mixtures of this brand are characterized by high strength characteristics. The composition is widely used in masonry blocks of cellular material, as well as for lining with a thin layer of blocks of internal and external surfaces. It turns out a seam with a thickness of 1-3 mm.

Glue is very popular due to the following properties:

there are no “cold bridges” in the masonry;
not exposed to moisture;
not afraid of severe frosts;
you can use the prepared solution for two hours, during which time it will not harden;
capable of passing steam.

The high adhesion of the mixture makes it possible to ensure the solidity and high strength of the buildings under construction. The adhesive consists of cement, mineral fillers, as well as organic and polymeric modifiers.

"Win"

It is a multicomponent dry mix based on cement, quartz sand and various modifying additives. It is used for laying silicate block structures. Glue is quite suitable for summer and winter work. The material is popular as it is compatible with most Russian-made gas blocks.

The ready-made solution is highly elastic and technologically advanced, does not stick to the instruments very much. The applied layer is characterized by good moisture resistance. The adhesive has excellent holding power.

Mixtures of this brand are used for thick-layer masonry in the winter and summer seasons. In addition to laying blocks, they are widely used in the installation of ceramic tiles, attaching it to the blocks. When applying the composition, it is not necessary to level the surface. You can leave slopes and drops up to 1.5 cm. It is often used for indoor work to level block walls.

All presented compositions are safe, endowed with good plasticity and able to withstand severe frosts. Which mixture is best, you will decide when you explore them empirically.

The answer to the question of which glue is the best is ambiguous. The fact is that we have presented the best adhesive mixtures, according to the opinion of builders who have checked all their advantages and disadvantages in their work. The selection of glue can be carried out not only on the basis of personal preferences. Be sure to take into account the type and conditions of laying work.

How to calculate glue consumption

The dry composition is packed by the manufacturer in bags weighing 25 kg. The manufacturer chose this number not by chance, since this is the optimal mass of powder for the preparation of glue, sufficient for laying one cubic meter of blocks. This is provided that the technology for the production of the mixture and its application are not violated.

Let's clearly analyze the calculation of glue consumption using an example:

Initially, you tentatively determined that for the laying of all walls you will need, say, 63 cubic meters of gas silicate blocks.
With a laying layer thickness of 3 mm, the consumption of glue per 1 cubic meter of blocks will be 63 packing bags.
If the laying seam is 2 mm thick, then the mass of the required adhesive will be 5 kg less. In this case, 63 cubic meters will have to be spent
63 x 20 = 1260 kg of dry glue.
Move on.
1260 / 25 = 50.4 bags.
Rounding up the figure, the result is 51 bags.
The calculated value is the smallest amount of dry mix that will need to be spent on the building. Provided that its construction involves the use of 63 cubic meters of aerated concrete blocks. If we know the price, we can easily determine the total cost of dry glue.

If the construction involves the use of a solution of cement and sand, and the amount of work will be the same, then you will need 2 cubic decimeters of glue. That is, 1 cubic meter of mortar is needed for laying 5 cubic meters of blocks.

To prepare a cube of mortar, you will need up to 7 packs of cement. The total cost will also increase due to the price of sand and the rental of a concrete mixer. Considering all this, it is not difficult to determine how much cement is needed to lay 1 cubic meter of gas silicate: 7/5 = 1.4 bags.

By doing the right cost calculations, it is easy to verify the low cost of the adhesive. The remaining priorities can only be set by you.

When erecting modern buildings, it is important to ensure reliable adhesion of materials, which is achieved through the use of high-quality glue for gas silicate blocks. A properly selected adhesive composition and an accurate calculation of its consumption are the key to the longevity of erected buildings.

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.
Estimation. 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.

The parameters when calculating the consumption of the solution per 1 m3 of the base are the thickness of the adhesive layer. With a layer thickness of not more than 3 mm per 1 m3 of surface, 8-9 kg of the working composition is required.

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.
