Silicate blocks are a very popular material among builders. They differ in operational characteristics simply remarkable. The walls of them are laid out not with cement mortar, but using special glue. Of course, the box will turn out reliable only if you use a high-quality fastener. We will talk about how to choose glue for gas silicate blocks.
What properties should a masonry mixture have
First of all, glue for gas silicate blocks should have such properties as:
In order to carry out the masonry was convenient, this type of glue also should not set too quickly. In this case, if necessary, the master will be able to correct the position of the already laid block. It is believed that glue for gas silicate blocks should not harden at least for 10-15 minutes. However, of course, and for too long a grappling composition cannot be considered a quality one. The optimum setting time is 3-4 hours.
Experts advise to purchase glue and gas silicate blocks in the kit. In this case, the composition will be as suitable as possible. However, it often happens that manufacturers of gas silicate blocks unreasonably overstate the cost of glue. Therefore, many owners of suburban areas, who decided to build houses of foam concrete, prefer to purchase a bonding composition still separately. When buying such a mixture, you should first of all pay attention to the brand of the manufacturer. This greatly increases the chances of acquiring a high-quality composition with good operational and performance characteristics.
Popular manufacturers
If you were wondering how to choose glue for gas silicate blocks, you should consider buying material of the following grades:
"Prestige".
Eunice Uniblock.
Aeroc.
"Win-160."
Bonolit.
"Zabudova."
All these compounds are environmentally friendly and highly plastic. It is about them on the network that there are the best reviews.
Glues of the Prestige brand
The main advantage of the compositions of this brand is fast cooking. Prestige glue can be used for laying not only blocks, but also cellular plates. It is a means of this brand is inexpensive. For a bag of 25 kg will have to pay about 140 rubles.
Composition "Unix Uniblock"
This is perhaps the most popular adhesive for gas silicate blocks today. "Which one to choose the best composition?" - Such a question usually does not arise among specialists. This mixture has just a lot of advantages:
excellent thermal insulation indicators, as close as possible to the characteristics of the foam concrete materials themselves;
moisture resistance and frost resistance;
ease of use;
environmental safety.
There is glue of this variety about 200 rubles per bag.
Mixtures Aeroc
The main advantages of the adhesive of this manufacturer include a high degree of strength. Most often it is used to perform thin-walled masonry. The advantages of this option are also considered frost resistance, moisture resistance and vapor permeability. The thickness of the joints in the masonry using this glue can be 1-3 mm, which completely eliminates the occurrence of cold bridges. A bag of such glue costs about 250 rubles. In terms of performance, this is perhaps the best glue for gas silicate blocks at the moment.
Composition "Bonolit"
The main advantage of this glue is its environmental friendliness. Any impurities harmful to health are completely absent in its composition. Its operational characteristics are also just wonderful. And it costs a little cheaper than glues of most other popular manufacturers - about 180 rubles per bag.
Means "Zabudova"
This glue is characterized by such advantages as ease of use and ease of application. Glue "Zabudova" - the cheapest version of the mixture of all intended for laying gas silicate blocks. Those who want to choose a glue for gas silicate blocks of good quality and at the same time save money should think about purchasing this particular option. A bag of 25 kg of the composition of this manufacturer costs only 120 rubles.
The best glue to use in winter
Next, let's see what glue to choose for gas silicate blocks in the event that the walls are laid in winter. For the construction of foam concrete houses in the cold season, almost all of the options described above can be used. However, when choosing the most suitable composition in the store, you should ask for the option with special additives (winter). Such compositions cost a little more than summer ones.
A very popular tool designed for laying blocks in winter is, for example, a special kind of Bonolit. Also, in the cold season, storekeepers often use winter glue for the KSZ gas-silicate block, produced by the Kostroma Silicate Plant. Adhesives intended for masonry in cold weather are also quite popular among builders:
How to cook glue
So, what kind of glue for gas silicate blocks to buy - we figured it out with you. Next, let's see how to properly prepare the selected composition. When kneading adhesives intended for fastening gas silicate blocks in masonry, the following recommendations must be observed:
The dry mixture must be added to water, and not vice versa.
Kneading should be carried out with a drill with a special nozzle. In this case, the glue will turn out to be as homogeneous as possible, and therefore, of high quality.
After the first batch, the composition should be kept for 5 minutes.
Use ready-made glue for a maximum of 2 hours.
When preparing glue, it is important to strictly observe the proportions indicated in the instructions. Too much water in the mixture significantly impairs its performance. During the production process, the finished glue should be mixed periodically to maintain concentration. When preparing the solution, a powerful drill should be used. You can take any water.
How to check the quality of glue
To find out how good a particular company offers when buying is, of course, quite difficult. However, it is still possible to determine which mixture is best for masonry. To do this, you just need to buy a little of each of the adhesives. Then they should be diluted according to the instructions in the same containers. After the glue dries, the resulting solid material must be weighed. The lightest glue can be considered the best. The smaller the weight of the material, the lower its degree of thermal conductivity.
If desired, you can also check the strength of the composition and its adhesive qualities. To do this, simply glue the two blocks, wait a while and sharply throw them on the ground. If they go apart at a seam, then it’s worth looking for another glue.
Well, now you know which glue to choose for silicate blocks is best in this or that case. When buying, first of all, you should pay attention to the brand of the manufacturer. If the masonry will be kept in the cold season, you should also look for the mark “winter” on the packaging.
