What glue is suitable for laying silicate blocks and how to use it?

Because of their longevity and capacity to insulate against heat, silicate blocks are a common choice in the construction industry. Selecting the appropriate adhesive is essential for ensuring a solid and long-lasting bond when laying these blocks. Silicate blocks, in contrast to conventional clay bricks, need particular adhesives made to stick to their surface.

A silicate-based adhesive is among the best kinds of glue for silicate block installation. This adhesive offers superior adhesion and structural integrity because it is designed to bond well with silicate materials. Typically, silicate-based adhesives are powders that must be activated by mixing them with water. When this mixture is applied to the blocks, it creates a strong bond that resembles cement.

It’s crucial to prepare the silicate blocks’ surface before adding the adhesive. To increase adhesion, make sure the blocks are dust-free, clean, and slightly moistened. By facilitating the adhesive’s proper surface grip, this preparation reduces the possibility of weak joints or bonding failures.

Make sure you carefully follow the manufacturer’s instructions when applying the silicate-based adhesive. Usually, to get the proper consistency, you will combine the adhesive powder with water. Apply the adhesive evenly to the block surface with a trowel, making sure to fully cover any areas that require extra strength, such as the corners and edges.

Once the adhesive has been applied, firmly press the silicate blocks into position. To make sure the adhesive spreads evenly between each block and the substrate and that each block is seated firmly, use a rubber mallet or other similar tool. When building more, wait for the adhesive to cure according to the manufacturer’s recommended drying time.

Installing silicate blocks correctly requires selecting the appropriate adhesive and applying it correctly. The structural integrity and insulating qualities of your construction project will be improved by a strong and long-lasting bond that you can achieve by following these instructions and using a high-quality silicate-based adhesive.

What composition is required for laying walls??

Many builders use conventional cement-sand mortar while still employing antiquated masonry techniques. However, this content is inappropriate for this place. You need to use specific adhesive compositions when laying gas silicate blocks. They are available in various varieties:

1. Summer. This composition is suitable for laying gas silicate blocks in the summer. It is also suitable if you plan to build partitions and walls indoors. Its application temperature is from +5 to +30 degrees. The composition cannot be used when working in the winter season. Frost resistance of this composition is 50 cycles, the recommended thickness between blocks is 10-20 mm. Good representatives of summer type glue would be Linker, Magma, Uniblock, Holcim. The average cost of such glue is 250 rubles. For example, Holcim glue (20 kg) will cost 220 rubles.
2. Universal. Available in gray color and suitable for work in summer and winter. The temperature range is wide enough to use this composition at both positive and negative temperatures. This means that the material is equally good for laying external walls and for constructing partitions. Such compositions are used at temperatures from -5 to +30 degrees. If it is necessary to use glue at temperatures below the specified temperature, then builders add an anti-frost additive to the mixture. The Malachite company produces such material, as well as the companies Rusean, Osnovit, Ivsil Block. The average cost is about 250 rubles. For example, for Ivsil Block (25 kg) you will have to pay about 200 rubles., For the Osovite Seltform (20 kg) – 180 rubles., And for RUSEAN (25 kg) – 150 rubles.
3. Winter. Such an adhesive composition is designed for laying gas silicate in the winter season. You can perform work at a temperature of up to -10 degrees: such properties allows you to achieve an anti -gun supplement. The frost resistance of this glue is 75 cycles. In this case, the solution in open form can exist 10 minutes, so the application process should be quick. The thickness of the layer of such a solution is 10-15 mm. Compounds are produced by Ceresiite, Perfekta. The average cost of compositions is 300 rubles. For example, Perfekta glue (25 kg) will cost about 250 rubles, and Bolars (25 kg) – 280 rubles.

Crucial! Every solution is offered for sale as powder. You must become familiar with and follow the instructions for kneading them. The bags weigh between twenty and twenty-five kg, and you need to prepare enough solution to last thirty minutes of work.

How to calculate consumption?

You must determine how much of the adhesive solution will be consumed in order to determine the precise cost. Frequently, the amount of material used is stated on the packaging using glue; however, artisans point out that this is insufficient. Making the calculations yourself is preferable. To accomplish this, you’ll need:

1. find out the dimensions of 1 gas silicate block;
2. find out the thickness of the seam that will be used during laying;
3. find out the surface area;
4. choose glue.

You can start to calculate once you are aware of all of the aforementioned indicators. For illustration, we will use Glue for gas silicate Etalon Teplit in our computation.

As a starting point, the typical gas silicate dimensions for masonry walls are 600x300x200 mm. You will require 10 kg of glue solution to lay 1 square meter of gas silicate blocks with a 10 mm seam thickness.

Additionally, the bags are made in 20–25 kg sizes, meaning that for a given laying, about half of a bag is required.

You can take into account the overall size of the masonry to ensure computation accuracy. The wall area, for instance, will measure twelve squares. This means that 180 kg of adhesive solution will be needed for its laying with a seam thickness of 15 mm. It is 7.2 bags, each weighing 25 kg, of glue in dry form.

Which composition to choose?

Although adhesive compositions are made based on seasonality categories, you must select a specific type of glue for each type of masonry.

For external load-bearing walls

It is preferable to use glue that is appropriate for the climate during the building year when laying exterior load-bearing walls.

It’s crucial to take breaks in between laying into account. Summer glue will work if you begin your project in the summer, when temperatures typically range from +20 to +30 degrees. It is advised to alter the composition in accordance with the surrounding temperature conditions if construction is carried out during the winter and early spring.

Winter and universal compositions are good choices for installing external load-bearing walls. It is best to be safe and use winter compounds since the walls will be in contact with the surrounding climate, particularly if the winters in the area are severe. It is preferable to use powder type glue that is frost- and moisture-resistant for work. It is extremely flexible, easy to work with, strong, and adhesive.

For internal carriers

Universal glue can be used inside buildings when building load-bearing walls. It comes in powder form and is available in a gray color. Its qualities make it ideal for applying gas silicate within homes. Experts advise moistening the block surfaces when the surrounding temperature rises above +30 degrees. Universal adhesives have a 50 cycle frost resistance, which indicates that the wall can withstand internal temperatures with ease.

For partitions

Universal composition or summer composition can be used to build partitions. You can use the recommended seam thickness from the glue manufacturer.

Summer glue will come in handy because it is frequently warmer inside the house when working.

A seam between 10 and 15 mm is advised by some craftsmen because partitions do not require as much thermal insulation as external walls do. It is preferable to use moisture-resistant adhesives when installing partitions in bathrooms or basements.

How to cook?

Since the final mixture should be plastic and simple to apply on blocks, it is advised to strictly abide by all packaging instructions provided by the manufacturer. The amount of water required to dilute the powder is frequently indicated on the package. Never disregard the manufacturer’s instructions as this could result in an overly liquid or overly thick final solution.

To get the glue ready, you’ll need:

1. pour the specified amount of water into the bucket;
2. pour the required amount of glue, observing the proportions;
3. pour the solution in a thin stream: for this it is convenient to first cut off the corner of the bag or use a ladle;
4. stir the solution with a drill with a “mixer” attachment or a special construction mixer;
5. let stand for 5 minutes;
6. Stir again and you can get to work.

Citation! The final glue should be about the consistency of sour cream.

For summer compositions, the glue needs to develop in 20 minutes, and for winter compositions, in 30 minutes. In masonry, correction is allowed for ten minutes. Avoid making a big batch of the solution ahead of time. Never dilute an already-hardened mass with water or a new solution; the masonry will be destroyed if this happens.

Materials and tools for installation

Prepare the standard supplies and equipment before laying a wall made of gas silicate blocks. It is worthwhile to give particular tools more thought:

• trowel;
• rubber mallet;
• wide spatula;
• notched spatula;
• special carriage.

The master applies the solution to a spatula with a trowel. Since a rubber mallet won’t damage the stone’s structure, it’s essential for fixing masonry blocks. A wide spatula is used to apply the composition, and a notched one is used to distribute it into strips. Leveling the adhesive layer between the blocks is done with a special carriage.

Step-by-step instructions

To adhere to all laying regulations, do as instructed:

1. Prepare the surface: clean the blocks from dust and dirt.
2. Mix the solution to the required consistency in the required quantity.
3. Apply the mixture to the blocks on 2 sides: the main and end.
4. Place on the masonry and level.
5. Wipe off excess adhesive with a rag.

Use a maximum seam thickness of 5 mm for external walls. Because the building material is insufficiently strong, external walls must be strengthened. Flexible ties or anchors are required to join the load-bearing internal walls to the external ones.

Pros and cons of use

While some builders are used to laying block material with cement-sand mortar, there are many benefits to using glue instead:

• there are no “cold bridges” on thin-seam masonry;
• the walls are smooth due to thin seams, so finishing costs are minimal;
• the thermal characteristics of the masonry are increased;
• the plasticity of the glue allows you to work with it conveniently;
• the composition is easy to mix;
• there is a financial benefit.

The composition’s strong temperature sensitivity is a drawback. For instance, the mixture will solidify more quickly if it is too high. The mixture within the masonry will solidify more slowly in colder temperatures. It is sufficient to follow the operating temperature specified on the packaging to prevent this.

Average prices

The adhesive compositions’ price per glue bag varies based on the manufacturer, supplier, and purchasing location. The solution’s seasonality—that is, whether it is meant to be used exclusively in the summer or winter or year-round—also has an impact on the cost.

An average bag of mixture (20–25 kg) will cost you roughly 300 rubles.

For silicate block construction, selecting the appropriate glue is essential to achieving a sturdy and long-lasting structure. Because of their superior acoustic and thermal insulation qualities, silicate blocks need a specific type of adhesive that can adhere to their porous surface.

A silicate-based adhesive is among the best kinds of glue for silicate blocks. This kind of adhesive has been specially designed to form a strong bond with silicate materials, withstanding a range of weather conditions and structural stresses. Silicate-based adhesives are convenient for construction projects because they usually come in a ready-to-use form.

It is crucial to properly prepare the surface before applying silicate adhesive. Make sure the silicate blocks’ surface is dust- and debris-free, dry, and clean. Better adhesion is encouraged by this preparation, which also guards against possible bonding problems that might eventually erode the structural integrity.

Using a notched trowel, liberally and evenly apply silicate adhesive to the back of each silicate block. The adhesive’s grip on the substrate and the block is enhanced by the ridges that the trowel’s notches help to form. In order to preserve structural integrity, make sure the blocks are level and properly aligned before pressing them into position.

Give the adhesive enough time to cure in accordance with the manufacturer’s instructions after placing the silicate blocks before adding any more loads or finishing touches. The adhesive reaches its peak strength during this curing time, resulting in a strong and dependable bond that adds to the construction’s overall longevity.

When working with silicate blocks, selecting the appropriate adhesive and adhering to correct installation methods are essential for a satisfactory result. Choose a high-quality silicate-based adhesive and follow best practices during installation to guarantee a sturdy and safe construction that satisfies aesthetic and functional needs.

Selecting the appropriate adhesive for silicate blocks is essential in the construction industry to guarantee stability and longevity. This article highlights application methods that optimize bonding strength while examining the important factors to take into account when choosing adhesive for silicate block projects. The longevity and quality of your building projects can be greatly enhanced by knowing how to use adhesive with silicate blocks, whether you’re a professional builder or a do-it-yourself enthusiast.
