Adhesive for gas blocks: reviews

For the laying of aerated concrete blocks a specially designed adhesive for this purpose is used. It allows you to stack products as tightly as possible to each other, so that the building has increased thermal insulation qualities. After all, these products are used not only for construction, but also for insulation of buildings and structures for different purposes. Mixtures for aerated concrete blocks should have high adhesion and thermal insulation qualities. They are made on the basis of polymer additives, cement, as well as sand and mineral fillers. Each ingredient performs its functions, providing plasticity, resistance to moisture, as well as increasing strength characteristics. It is these qualities that the composition that you will use in the course of the work must have.

Reviews about the advantages of glue for aerated concrete blocks in front of analog options

The adhesive for gas blocks has certain advantages, which is true if compared with analog compounds that have a different purpose. Thus, these mixtures are characterized by high plasticity, frost-resistance, fast enough setting, moisture-repelling characteristics, and also excellent adhesion. According to users, thanks to the presence of Portland cement and high-quality sand, in the process of laying it is possible to make the thickness of the joints, which is equal to two millimeters. If it is a polyurethane adhesive, it does not shrink during drying, which prevents the formation of cold bridges. After all, they cause the walls to let the heat out.

As the home craftsmen who were engaged in laying down the described items emphasize, the adhesive for gas blocks is very convenient to use, for its preparation it is enough to mix dry concentrate with the liquid, the proportion recommended by the manufacturer should be taken into account. Despite quick setting, the solution remains viable for a few hours after mixing. Consumers choose these formulations because they have a 95% moisture resistance, their holding time is fifteen minutes, the blocks can be adjusted within three minutes after being put in place. Internal fillers have a grain size of 0,67 millimeters, and it is possible to work with these mixtures for a wide temperature range - from +5 to +25 degrees Celsius.

Reviews of frost-resistant adhesives for aerated concrete

The adhesive for gas blocks can have increased frost-resistant characteristics. According to buyers, these compositions should differ in certain features. Although the antifreeze additives are included , it is not recommended to use winter glue if the temperature falls below -10 degrees Celsius. The glue for gas blocks of high frost resistance, according to users, should have a gray color, environmental friendliness, resistance to aggressive natural influences, the ability to operate both inside and outside the premises. The mixtures should be characterized by low thermal losses, as well as the ability to prevent the appearance of cold bridges.

Reviews of products from different manufacturers

If you want to use gas-block adhesive for work, it is recommended to read reviews about it. As users emphasize, the mixture and Kreps has the optimal composition and high performance. This product can be used both outdoors and indoors, among its characteristics - efficiency and economy.

It is important to pay attention to the technical characteristics, including the maximum grain size of the filler, which can reach a parameter of 0.6 millimeters; And the thickness of the layer, in this case it is equal to 3 millimeters. As practice shows and the master claims, the exposure time is equivalent to 10 minutes, the block can be adjusted within the same period. Full drying will occur in 4 hours. You should consider the average expense, this will save money that could be spent on the purchase of unclaimed packs of glue. At 1 cubic meter will take about 25 kilograms of the composition.

Reviews about glue "Azolite"

No less effective for winter construction composition "Azolit", which differs moisture-repellent characteristics and is intended for laying not only aerated concrete, but also silicate, as well as foam concrete products. Consumers claim that the average consumption per 1 cubic meter is 25 kilograms, the glue mobility is maintained for 7 minutes maximum, the bending strength is 4.1 MPa. Full drying should be expected 2 hours after mixing, and the moisture content by mass is 0.08%. Quite often specialists are interested in such a parameter as compressive strength, in the case of the composition "Azolit" it is equivalent to 11.2 kg / m². Moisture absorption by weight is 2 percent, but adhesion to the concrete base is 0.4 MPa.

Reviews about glue Axton

Adhesive for gas blocks Axton is now popular among consumers, it is a dry mix, which is intended for solution preparation. Use this compound can be for outdoor works, where not only gas blocks, but also brick, as well as any other products are involved. Users like that this adhesive is able to undergo the effects of temperatures in a fairly wide range - from -50 to +50 degrees Celsius. Among other things, the product is easy to prepare, high strength of the compounds formed, accurate dosage of components, as well as low consumption of the mixture during work.

The described adhesive for the gas-block laying is made in Russia, therefore its cost is insignificant and is 185 rubles. For a 25 kg bag. Drying should be expected after 24 hours minimum, while the maximum limit is 48 hours. Adhesion is 0.4 MPa. According to users, the thickness of the seam can vary from 2 to 5 millimeters, this allows you to level out the unevenness of the blocks. The composition can be stored for 120 minutes, and adjust individual blocks after laying - for 10 minutes.

Qualitative characteristics of Axton glue

If you decide to use glue for Axton gas blocks (25 kg), you should know that the mentioned volume will be enough for 1.22 cubic meters. The composition is presented for sale in the form of a gray powder, which can be used after mixing during the laying of blocks that have grooves or are deprived of them.

Using the adhesive "Akston"

According to experienced users, to work with this adhesive it is necessary to prepare a notched trowel, trowel or steel spatula. The application on the surface is made as flat as possible, which can be leveled using a toothed working surface. Once the adhesive for Axton gas units, the feedback about which will help you decide the choice, was applied to the base, you can lay the product, the position of which is leveled with a hammer. Excess amount of the mixture must be removed by the trowel.

Reviews recommend preparing such an amount of composition that you will be able to work out in a short time, otherwise the solution will lose its elasticity, and you will run into a material overexpenditure. It is important to prepare for mixing hot water, the temperature of which is 60 degrees.

Conclusion

Adhesive for gas units Axton (25 kg), which are positive reviews, should be applied to a pre-prepared surface that must be dust-free. To do this, the base is cleaned with a soft brush. It is necessary to follow up also that on a surface of products there were no fat stains, otherwise the basis should be degreased.
