What is adhesive for foam and aerated concrete
Let’s start by talking about the adhesive’s composition and the benefits it offers over a homemade solution.
Why a specialized composition is better than a solution?
There is only one discernible drawback, and it has many benefits. Since its cost cannot be considered budgetary, developers frequently choose low-cost cement-sand mortar, never mind that it is unlikely to result in cost savings in the long run.
This assertion is supported by a number of factors, but it is important to begin by acknowledging the necessity of employing an adhesive mixture.
- Foam and gas blocks are characterized by a high ability to retain temperature, and this is one of the main advantages of the materials. And in order to keep it as such, it is necessary to reduce cold bridges as much as possible.
- The thickness of the layer when using glue and good block geometry should be minimal, which will reduce those very cold bridges that contribute to the outflow of heat.
- Cement, in turn, is quite the opposite, is characterized by a low ability to retain heat. And therefore, it will contribute to the reverse reaction. Moreover, the thickness of the layer when laying blocks on mortar is much greater.
Now, let us ascertain what additional advantages the adhesive composition of cellular concrete possesses.
- Since we are talking about the cost of the work, let"s find out if this is really so? Let"s assume that the developer decided to use the services of masons. The adhesive mixture is mixed quickly and does not require much labor.
Note: Everything is different when it comes to mortar; it will require more time and work. The cost of work will go up as a result. Furthermore, if you wish to keep the appropriate capacity to retain heat, you will need to insulate the walls more thoroughly because there will be a greater number of cold bridges. Costs rise as a result.
- If the block used is of the first accuracy category and has almost ideal geometry, laying one cube will not take more than 25-30 minutes. Of course, a mandatory condition for this is the skill of the mason.
- The mortar is easy to work with, it is plastic, it is applied well.
- The mixtures are characterized by resistance to biological damage.
- They have high tear strength.
- The construction materials market offers mixtures containing a specialized additive that allows you to carry out work on laying blocks in the winter at sub-zero temperatures.
Kindly take note! The costs associated with using the solution will not decrease; on the contrary, they will rise when all potential expenses are taken into account. This covers the cost of time, effort, insulation, and any subsequent heating, among many other things. Thus, we have successfully disproved the notion that the primary justification for switching from glue to the solution was its unprofitability.
How much glue will be needed and what costs still await the developer
What factors influence how much glue is consumed?
There are multiple factors that impact this:
- Characteristics of the product itself. The material of different manufacturers differs from each other in the predominance of certain properties, which explains the different consumption. However, in general, it does not differ dramatically.
- The thickness of the layer itself, of course, affects the consumption. It can vary from 0.5 to 3 mm. The geometry of the block largely determines this value.
- The skill of the installation specialist is also a determining factor. The higher it is, the more likely it is that glue consumption will be reduced.
- It is worth mentioning the weather conditions and the evenness of the base of the building. These factors also affect the mixture consumption.
Take note: Many manufacturers state that the composition will be consumed at a rate of approximately one bag per cubic meter of masonry with proper product geometry. Practice, however, demonstrates that this quantity of glue is insufficient. Purchasing material with a minimum reserve—that is, at least 10% extra—would be reasonable.
For cellular concrete, selecting the appropriate adhesive is essential to guaranteeing robust, long-lasting bonds and effective construction. Specialized adhesives, as opposed to conventional mortar, are made to specifically work with the special qualities of cellular concrete, providing improved adhesion, faster setting times, and reduced mess. Because of this, they are the perfect option for both experienced builders and do-it-yourselfers searching for a dependable, user-friendly solution that improves the general caliber and durability of their projects.
Choosing a specialized solution
Selecting a product brand can prove to be a challenging endeavor at times. There is a large selection. On the market for building supplies, there are many different manufacturers with mixtures that vary from one another in a number of ways.
Additionally, everyone emphasizes a particular set of features in an effort to set their products apart from those of rivals. This can include things like high strength and resistance to the atmosphere, enhanced vitality and flexibility, and more. It’s crucial to make the right decision every time.
Let’s take a quick look at a few well-known brands and assess the significance of various attributes.

Types of adhesive mixture and application features
The types of adhesive mixtures are shown in the winter and summer compositions. Certain characteristics of the winter composition for cellular concrete are related to both the composition and the application.
- The winter mixture contains a specialized anti-freeze additive, which allows the composition to be used at sub-zero temperatures. As a rule, the summer version should not be used at temperatures below plus 5.
- If the work is carried out in the summer, when the air temperature is warm, then in most cases, of course, the usual mixture is used.
- However, if the developer for some reason purchased the winter version, then it can be used. But the opposite should not be done. That is, summer glue is not suitable for laying in winter.
When using winter glue for masonry work, it’s important to abide by these basic guidelines:
- Do not mix the solution in large quantities, it must be used up within about 30 minutes;
- The water should be warm, adding it to dilute the cooled mixture is not recommended;
- The block must be cleared of ice and snow.
Stages of work on laying foam and gas blocks
You are capable of laying the block by yourself. Let’s take a closer look at each step, beginning with the supplies and guidelines needed to mix the glue.
Preparing materials and tools
The following supplies and equipment are required:
- Building level;
- Scraper bucket with a serrated edge;
- Square;
- Container for mixing the solution;
- Drill and mixer attachment;
- Building float;
- Building cord;
- Reinforcement;
- Saw or hacksaw;
- Electric or manual wall chaser;
- Sand, cement, water for mixing the solution and adhesive composition.
We then go ahead and get the adhesive composition ready:
- Be sure to follow the manufacturer"s recommendations;
- The consistency should not be too thick or liquid;
- The amount of mixture when kneading should not be too large, since it sets relatively quickly and needs time to be worked out
You can begin lying as soon as everything is prepared.
