Glue is a mixture of elements, thanks to which it is possible to achieve tenacity with various materials. But for the durability of the resulting seam, you should focus on a quality product, especially if you have to glue gas silicate blocks. Such adhesive can be obtained from sand, cement, organic and plasticizers. mineral origin. Today, the construction market for gluing gas silicate blocks has a large number of compositions, the choice of which depends on the preferences of the owner, as well as the conditions for laying the material. Let's consider which options are best to choose in terms of price/quality ratio.

Frost-resistant for laying blocks in winter

When determining the the best glue for gas silicate blocks, it is necessary to take into account reviews from consumers who have already been able to evaluate the quality of the products from their own experience. Let's consider the most popular and high-quality brands of masonry adhesive in winter.

Zabudova

This composition is perfect for laying blocks in winter time. The reason is in the components that make up it. There is a special additive that is not affected even by severe frost (frost-resistant). Many builders speak positively about this product, because the glue is characterized by such advantages as ease of application and ease of use. In addition, the cost of Zabudov is not high, which allows the adhesive composition to occupy a leading position in the market of ready-made dry mixes. The cost of production is 120 rubles per bag.

Prestige

This composition is also not afraid of frost. It can be used for laying cellular blocks and even slabs. Characteristic feature glue remains it quick cooking. The cost of the composition is slightly higher than that of the first option. For a 25 kg bag you will pay an average of 140 rubles.

Eunice Uniblock

Uniblock glue is now actively used for laying gas silicate blocks. The reason for this popularity is due to the set positive qualities, which include the following:

AEROC glue

These products are characterized by high strength characteristics. Glue is actively used for laying blocks of cellular concrete when providing thin-layer laying of external and external walls. The thickness of the resulting layer is 1-3 mm.

The high popularity of the product is due to its following characteristics:

  • there is no formation of “cold bridges”;
  • not affected by moisture;
  • severe frosts are not scary;
  • It is allowed to use the prepared solution within 2 hours, as it will not harden;
  • vapor permeable.

Due to high adhesion, it is possible to achieve solidity and high strength characteristics of the building being constructed. The adhesive contains the following components: cement, mineral fillers, modifiers of organic and polymer origin. The cost of a bag is 250 rubles.

This composition is presented in the form of a multicomponent dry mixture, which is based on cement, quartz sand and various modifying additives. Glue is used for laying gas silicate blocks. You can purchase the mixture for work in summer or winter. This product is also very popular, because it is suitable for most gas blocks produced in Russia. After preparing the composition, it is characterized by high plasticity and manufacturability. It does not stick strongly to the instrument, and after application it forms a good moisture-resistant layer. The glue is characterized by high fixing ability. The cost of the product is 190 rubles per bag.

Purchasing this mixture involves its use for thick-layer laying of gas silicate blocks not only in winter, but also in summer. In addition to laying blocks, it is actively used when installing tiles, sides and slabs, as well as other highly porous materials with further coating. When using this glue, it is not necessary to level the surface. Changes and slopes can reach up to 15 mm. Can be used inside the house to level walls built from the sides. The product costs 190 rubles.

Which gas silicate glue is better to choose?

There is no clear answer to this question. The reason is that the best adhesive compositions were presented above, according to the reviews of many people who have experienced all their pros and cons. Choice adhesive composition should be carried out not only taking into account personal wishes. Here it is important to take into account the type of work and the conditions for laying the block.

Each of the available products has a safe composition, high plasticity, and can be used for severe frosts. Today, the best adhesive compositions are the products listed above, and only you can choose which is the best when you do your research when working with them. Some prefer to use it for installation.

The video explains which glue to choose for gas silicate blocks:

Flow calculation technology

If all the rules for producing the mixture and applying it to the blocks have been followed, then its consumption can be carried out in the following ways: glue is sold in bags weighing 25 kg. This value was not chosen by chance by the manufacturer, because the weight of dry glue is optimal for laying 1 m3 of blocks. Thanks to this, the consumption of the composition will be very easy to carry out. Let's look at this in more detail using an example:

  1. After you have calculated everything, it turns out that to lay the walls and partitions you will need, say, 63 m3 of aerated concrete.
  2. If the thickness of the laying layer is 3 mm, then the consumption of the adhesive composition per 1 m3 of blocks will be 63 bags.
  3. When the thickness of the seam between the laying blocks is 2 mm, the amount of glue consumed will decrease by 5 kg. Then for 63 m3 you will have to spend 20x63 = 1260 kg of mixture. Next, 1260/25= 50, 4 bags. Round up and get 51 bags of glue.
  4. The obtained value is the smallest amount of glue that needs to be spent to erect a building, the construction of which involves the use of 63 m3 of aerated concrete. When the price is known, you can simply find out the cost adhesive solution.

In the video - winter glue for gas silicate blocks:

If you use a cement-sand mortar for installation for such a volume of work, then here you will need 2 dm 3 of glue. Thus, 1 cube of the mixture will be used to lay 4 cubes of blocks. To prepare a cube of mortar, you will need 7 bags of cement. The price will also have to include the price of sand, purchase or rental of a concrete mixer. Taking all this into account, you can obtain the amount of mixture required to lay 1 m3 of aerated concrete: 7/5 = 1.4 bags.

Construction modern houses Most often it is carried out from gas silicate blocks. For strong adhesion, it is very important to choose a high-quality adhesive composition and accurately calculate its consumption. Thus, you can save money if you buy glue in larger quantities. The constructed structure, if all conditions are met, will serve you for a long time without the formation of certain defects.

The construction of buildings made of aerated concrete has ceased to be outlandish. This material is rapidly conquering the market due to its lightness and good performance characteristics. Such construction requires the use of special solutions, since standard cement ones are not particularly suitable for such purposes (the joints are too rough). Professionals recommend the use of special adhesives. What are they, how to calculate material costs, what do manufacturers now offer?

Where is it used?

Adhesive for aerated concrete is a special dry construction mixture, which is diluted with water in the proportions specified by the manufacturer. It is used instead of conventional cement mortars for both external and internal work.

Use it for:

  • masonry of blocks made of gas and foam concrete, expanded clay and brick;
  • leveling wall surfaces, puttingty them;
  • laying ceramic tiles.

Seasonal varieties


Universal gray glue is used not only in winter, but also in summer.

Nowadays two types of mixtures are used for the construction of buildings. Adhesive for aerated concrete blocks is:

  • White. It is considered summer, used in warm seasons. Light shade(same as ) he is obliged white Portland cement, which makes it possible to save on interior decoration.
  • Gray. Although this type is called winter, it is universal and suitable for work in any season. Due to the presence of antifreeze additives in the composition, it is recommended for use in cold weather, however, it also has a certain temperature limit.

Composition and characteristics of the mixture

The composition of aerated concrete adhesive includes:

  • high quality cement;
  • fractionated (sifted in a special way) sand;
  • polymer additives that serve to improve the adhesive qualities of mixtures and their thermal conductivity;
  • modifiers, thanks to which the seams do not crack when temperatures rise.

The advantages of compositions for working with aerated concrete include the following characteristics:

  • the ability to make thin seams (only two to three millimeters thick), which reduces heat loss through the joints and reduces construction costs;
  • frost and moisture resistance;
  • the ability to carry out work in cold weather (with winter glue);
  • hardening without shrinkage.

Mode of application

Required Tools

To prepare the solution you will need:

  • a container in which you will need to stir the dry bulk mixture with water;
  • a drill with a special attachment (to obtain the correct consistency of sour cream, use a construction mixer);
  • measuring device to maintain correct proportions.

To apply glue and carry out masonry, use a steel or notched trowel or a trowel-bucket (carriage) for aerated concrete.

Cooking method

Dry mixtures are sold in 25 kg bags. To prepare the adhesive composition, the calculation is as follows: one factory package requires five to five and a half liters clean water(that is, 200-220 milligrams are taken per 1 kg). The liquid should be warm (from 15-18 to 60 °C).

After kneading, you should get a mass without lumps. It needs to be allowed to “settle” for five to ten minutes, and then stirred again. The glue is usable for only a couple of hours, so it is prepared in portions.

Application method

Apply aerated concrete adhesive in a minimal layer to clean blocks (without dust, dirt, or oil stains). The thickness of the joints during laying should not exceed 2-4 millimeters. The excess is removed immediately or cut off with a trowel after hardening. The position of the blocks can be adjusted within about ten minutes (perhaps with a rubber hammer). Level the surface by lightly tapping

Note. It is necessary to protect yourself from getting the prepared solution into your eyes and skin, so it is recommended to use protective clothing and gloves. A respirator or gauze bandage will not interfere.

Works in winter

For masonry in cold weather, a gray winter composition is used. However, as we have already mentioned, there is also a certain threshold for it (the “overboard” temperature cannot be lower than -10 °C; manufacturers usually recommend a value of 5 °C). For the solution itself, the temperature is maintained above zero - only if this condition good adhesion of materials is ensured.

Note. Do not glue frozen blocks covered with snow together - this is not allowed according to technology.

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

Types of blocks used

The construction of a new architectural project invariably entails the selection 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 This is due to the laboriousness of laying bricks. In addition, the price of ceramic analogues of bricks is significantly higher compared to the cost of glue for foam blocks.

Today steel is a worthy replacement for brick building blocks, presented in a wide variety on the construction market. Their main varieties are the following:

  1. Expanded clay concrete blocks. The material has a number of advantages. It successfully combines qualities such as high strength and low weight. The use of blocks involves a small investment of time to create durable masonry. Expanded clay concrete block elements allow the construction of buildings up to 3 floors high manually, without the use of special equipment.
  2. Concrete blocks. In construction residential buildings this material is rarely used because it has 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 profitability of their use is due to significant cost savings. The small dimensions of the gas silicate block save useful space.
  4. Polystyrene concrete blocks. When creating them, a special substance is added to a regular concrete solution, which helps make the material frost-resistant and has good properties. soundproofing properties, durable. The low price of polystyrene concrete blocks makes the final cost of construction low. Polystyrene concrete blocks are used in both private and industrial construction.
  5. Foam concrete blocks. When carrying out construction using foam concrete blocks, there is no need to use special equipment if the height of the building does not exceed 3 floors. Its application foam concrete blocks found in the field of cottage construction. 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 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 mix a cement-based solution, 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 various 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 reasonable material consumption for laying 30 blocks with standard parameters(600*200*300) one bag of dry adhesive mass is used.

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

For foam blocks

Adhesive 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 classic cement mortar. Among the components of block glue is quartz sand, crushed to the smallest fraction.

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

After applying the adhesive composition, its thickness is minimal due to the absence of coarse components. In addition, the solution quickly gains strength due to the use of high-quality Portland cement in its composition. When laying a foam block on glue or a mortar with an adhesive base, you should know that this material consists of a whole complex 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. The presence of special additives in the adhesive mortar gives the seams between the blocks greater plasticity than that found in ordinary cement mortar.

Such a property as plasticity reduces the likelihood of deformations in the masonry, the appearance of cracks, distortions and cracks in the wall made of blocks. The inclusion of auxiliary additives by manufacturers in the adhesive composition allows them 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 with negative temperatures up to -15 ºC.

For ceramic blocks

The use of ceramic blocks for the construction of buildings in Lately becomes more in demand. Ceramic blocks Outwardly they look like bricks, but inside they are empty. They are made from baked clay, and the dimensions of such building materials are significantly larger than those of ordinary bricks. Due to the internal void, the thermal conductivity of the material is reduced, and thermal insulation properties, on the contrary, increase.

To ensure that ceramic blocks are laid perfectly, experts recommend using special glue. This solution helps 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 allows the formation of a uniform heat-insulating plane.

Adhesive for ceramic blocks is made from 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 from lightweight concrete. They contain mineral compounds of organic origin. The main components of the adhesive solution are water, Portland cement and additives, including small polystyrene foam granules that have a porous structure.

The unique combination of various useful components in the glue gives the finished walls such characteristics as good hydrophobicity, good thermal insulation properties, resistance to rotting, good load-bearing capacity, transmitted and finished walls. This adhesive composition is sold in the form of a dry mixture, and requires mixing the powder with water and thorough stirring before use.

For gas silicate blocks

Glue for cellular blocks, which also has another name - gas silicate, is presented in stores various brands, personifying different manufacturers. Prices for glue for gas silicate blocks vary between 115-280 rubles, but this cost does not always indicate good quality adhesive composition. Sometimes the consumer has to overpay money just for a well-promoted brand. To avoid making a mistake, construction experts advise purchasing from the manufacturer not only the glue itself, but also building blocks of the required variety. According to statistics, the use of gas silicate blocks helps reduce the final cost of construction by approximately 40%.

Adhesive for gas silicate blocks has several beneficial benefits, namely:

  • Low cost. Glue consumption for gas silicate blocks is approximately 6 times lower compared to cement-sand mortar, and the cost is only twice as much.
  • Resistance of the composition to atmospheric precipitation (snow, wind, rain).
  • No cold bridges. There are no layers formed in the material, characterized by high level thermal conductivity, causing a decrease in the uniformity of block masonry.
  • High strength. If we compare the glue for gas silicate blocks with the cement-sand mortar mentioned above, it helps to form masonry from blocks of greater strength.

When choosing adhesive for a gas block, you should pay attention to its composition and technical characteristics, because such information will help to create 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.

It will be useful to know what the fraction size is bulk materials components included in the solution, at what temperatures the manufacturer recommends using the product, what the recommended layer thickness should be. It is also worth paying attention to the label, which displays useful data on the drying period of the adhesive solution, the amount of adhesive used during the work, etc.

Universal glue

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

How to calculate how much glue you will need

Glue consumption when laying foam block walls depends on several factors. Important when performing calculations, it has the type of block element. For example, for a cellular block of glue you will need more, since the material is porous, which means it absorbs moisture well. Also, the level of consumption depends on the brand and manufacturer of the adhesive composition.

In general, the consumption of any type of glue for blocks is more economical compared to a conventional solution of sand and cement. Laying blocks with its use is obtained with thin seams, and accordingly, the consumption of the composition is reduced by about 6 times. The use of such modern material as block glue makes it possible to achieve a seam thickness of a maximum of 5 mm, and if installation technologies are followed, 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 glue consumption. If the building material is uneven, then more adhesive solution will be needed for its installation.

To minimize solution costs, it is important to determine how much glue is needed to lay a cube of foam blocks. Knowing this information and also exact amount block elements, you can easily calculate the amount of dry glue required for construction. According to the standards established in construction, the consumption of aerated concrete adhesive per 1 m 3 is no more than 1.6 kg, provided that the joint is thin 1 mm. However, this condition is met only with a perfectly flat surface. Sometimes up to 30 kg of dry adhesive composition is used for 1 m 3 of building material. On average per 1 cubic meter. gas blocks, you have to waste 1 bag of adhesive composition weighing 25 kg. But this is only from a theoretical point of view. Often the waste is 1.5 packages of dry weight, 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 masonry worker has a great influence on the quality of workmanship.
  • Surface irregularities increase the consumption of glue for blocks.
  • The number of layers of 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.

Wondering what glue consumption is aerated concrete blocks optimal, you should be aware that it will be smaller 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 different recommendations regarding what the glue consumption for 20*30*60 foam blocks should be.

They concern not only dilution, 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 before you start mixing the adhesive solution from the dry mass.
  2. Follow the technology for preparing the composition, then the material consumption will be less, and accordingly, the cost of glue for the foam block will be reduced.
  3. When laying foam blocks on prepared glue, observe the temperature conditions required by the manufacturer.
  4. To maintain the homogeneity of the composition, stir it periodically while laying the blocks.
  5. At self-installation blocks for glue and lack of proper experience from the master, it is better to purchase all materials with a reserve.
  6. By applying glue to the surface of the block with a notched trowel, 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 site where the block walls are being erected.

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

For quick installation of slabs and blocks made of aerated concrete, foam concrete and gas silicate, adhesive for gas silicate blocks is used. The price of block adhesive depends on the type, brand, base material and application. Adhesive for gas silicate blocks is produced using cement based and fine sand with various additives.

  • plastic;
  • weatherproof;
  • moisture resistant;
  • economical.
  • sets quickly.

Before applying glue for gas silicate blocks, it is necessary to carefully prepare the base - clean it of dirt and degrease it. The dry construction mixture is mixed with water until a ready-made solution is obtained, after which it is applied to the surface using a notched trowel. This glue forms a thin, strong seam between the blocks, which significantly improves the wear resistance of the structure.

For finishing building facades in modern construction Special blocks from modern materials. They have good technical characteristics, look great, are relatively inexpensive and very easy to use. For fastening, adhesive for gas silicate blocks is used, which fully satisfies all current safety standards.

Light 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 you need to use not an ordinary solution, but special mixture. Therefore, many are interested in the question, which adhesive for gas silicate blocks is better?

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

Types and composition of glue

There are several types of glue:

  • - mixture for indoor masonry;
  • - mixture for masonry outside;
  • - mixture for masonry indoors and outdoors;
  • - a mixture for laying on top of heated floors with special enhanced thermal conductivity and resistance to temperature effects;
  • - mixture for masonry in places with high humidity and for finishing swimming pools. Highly resistant to moisture;
  • - a universal mixture with an increased hardening rate.

All of the listed 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 large wholesale purchases, you can save a decent amount, so it is important to correctly calculate the amount of materials required for repairs, so that during the work you do not have to purchase the missing amount.

The more universal properties the glue has, the more expensive it will cost. But save on building materials it is forbidden. Small benefit in this moment will lead to huge losses 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 resolve the issue of home decoration for many years to come.

The composition of the glue includes fractionated sand, Portland cement and special chemical compounds, which are responsible for 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. Preparation of the working solution is no different from the standard procedure. Simply add to a container of water required amount dry mixture and mix thoroughly until a homogeneous mass is formed.

Features of working with glue

The work is done using a regular trowel or spatula. Laying of gas silicate blocks on 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 the seams are not visible. The width of the adhesive layer should be 2-15 millimeters, depending on the situation. Excess solution is removed from the surface using a damp cloth.

The glue dries in 2-24 hours depending on atmospheric conditions. It will take 7-10 days for it to reach its maximum density, so for the first time after repair it is better not to perform any manipulations with the treated surface. Glue consumption 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 necessary for use.

The treated surface is pre-prepared for repair. To do this, it is leveled and primed. You can also carry out antifungal treatment using 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 adhesive 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 corrosion-resistant metal alloys of medium hardness.
  2. At high temperature environment and low air humidity, it is necessary to prime the surface to be treated immediately before installation. This will increase the level of adhesion of the mortar to the walls.
  3. It is necessary to carry out work wearing protective gloves and special glasses. If the composition gets into your eyes, you should immediately consult a doctor.
  4. Not worth it for a long time store the dry mixture under conditions high humidity, as this may render it unusable.

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