Aerated concrete walls are valued for their precise geometry, low thermal conductivity, and ability to maintain a comfortable indoor microclimate. A high-quality aerated concrete block provides a smooth base for subsequent finishing works, helping reduce material consumption and ensuring a durable result.

ARTON products are manufactured from mineral raw materials using autoclave curing technology and undergo quality control at every stage of production. As a result, our autoclaved aerated concrete blocks feature stable characteristics that are important not only during construction but also when carrying out interior finishing works.

Aerated concrete has a porous structure and high vapor permeability. For this reason, finishing materials should preserve the walls’ ability to allow water vapor to pass through and should not interfere with natural air exchange inside the building. This approach helps maintain thermal comfort, reduce the risk of moisture accumulation, and improve the overall efficiency of building operation.

Which Types of Finishes Are Suitable for Aerated Concrete Walls

If you are planning to buy aerated concrete for a residential project, it is advisable to consider the interior finishing system in advance so that all materials work together as a unified solution. When selecting mixtures, it is important to take into account the characteristics of the substrate. Autoclaved aerated concrete blocks provide good adhesion; however, they require compounds specifically designed for cellular concrete.

High-quality aerated concrete usually still requires interior finishing, but the amount of work and its cost can be significantly lower due to the precise geometry of the blocks. If the aerated concrete is of high quality (for example, D400–D500 with accurate geometry), the following system is typically used for residential premises:

• Deep-penetration primer.
• Thin-layer gypsum plaster (typically 3–10 mm).
• Finishing putty.
• Paint or wallpaper.

Thanks to the smooth walls, there is no need to apply a thick plaster layer of 20–30 mm, which is often necessary when working with brick or blocks of poor geometry.

Is it possible to do without plaster?

• Technically yes, if the masonry has been completed to a very high standard.

In this case, the finishing system may look as follows:

• Primer.
• Reinforcing fiberglass fleece or fiberglass mesh (optional).
• Base putty.
• Finishing putty.
• Painting.

However, this option requires almost perfect masonry workmanship and is therefore used less frequently. For wet areas such as bathrooms, laundry rooms, and boiler rooms, the following solutions are recommended:

• Cement or cement-lime plaster;
• Waterproofing in wet zones;
• Tiles or moisture-resistant finishes.

Gypsum plasters are not always used under tiles in permanently humid environments.

What should be avoided? For aerated concrete, the following practices are not recommended:

• Covering walls with vapor-impermeable materials without necessity;
• Using dense cement-based compounds not intended for cellular concrete;
• Applying heavy plaster in thick layers without reinforcement.

Aerated concrete is valued specifically for its vapor permeability, which means that finishing materials should preserve the wall’s ability to “breathe.” When working with high-quality autoclaved aerated concrete that has precise geometry, the optimal solution for interior spaces is generally considered to be:

• Primer → thin-layer gypsum plaster → finishing putty → paint/wallpaper.

This system provides a smooth surface, protects the blocks from mechanical damage, and preserves the advantages of aerated concrete.

Each material should meet the required vapor permeability and adhesion standards. The use of excessively dense coatings may create barriers to natural moisture exchange. This requirement is particularly important for buildings where facing aerated concrete blocks or other cellular concrete elements are used.

An additional advantage is the precise geometry of ARTON blocks. The smooth surface allows the plaster layer to be applied evenly and helps reduce the consumption of finishing materials.

How to Prevent Cracks and Finish Delamination

Even a highly durable substrate does not guarantee the absence of defects if construction technology is not followed correctly. Cracks most often appear due to improper surface preparation or incorrect material selection.

To reduce the likelihood of such issues, it is recommended to follow these guidelines:

• Clean the substrate from dust before applying primer;
• Use compounds specifically designed for aerated concrete surfaces;
• Maintain the recommended plaster layer thickness;
• Allow sufficient drying time for each layer;
• Use reinforcement in potentially high-stress areas;
• Maintain a stable temperature regime during the work;
• Prevent finishing materials from drying too quickly.

When selecting blocks, it is not advisable to focus solely on the price of wall aerated concrete blocks. It is much more important to consider product geometry, density indicators, and production consistency. A high-quality substrate helps distribute loads from finishing layers evenly and reduces the risk of deformation.

The delivery of aerated concrete blocks also plays an important role, since damage during transportation may affect the future condition of the surface. ARTON aerated concrete blocks are manufactured using modern equipment and undergo laboratory quality control, ensuring predictable and consistent performance characteristics.

Fasteners for Aerated Concrete and Preparing Walls for Decorative Finishing

After rough construction work has been completed, it is necessary to select fastening elements correctly. The porous material requires specialized solutions designed to work with the cellular structure of the substrate. The following fastening options are commonly used for installing various structures:

Dowels for aerated concrete;

• Chemical anchors for critical load-bearing connections;
• Frame fastening systems;
• Special screws for cellular concrete;
• Anchor elements for wall-mounted furniture;
• Reinforced fasteners for engineering equipment.

The specific type of fastener is selected according to the weight of the structure and operating conditions. This approach ensures reliable installation of shelves, kitchen cabinets, water heaters, and other interior elements.

Before decorative finishing, the surface is additionally puttied and sanded, creating a new smooth layer for painting or wallpaper application. If you plan to buy aerated concrete blocks in Uzbekistan for a residential or commercial project, it is advisable to consider future fastening points for equipment in advance. This will help avoid unnecessary modifications after renovation work has been completed.

Today, ARTON products cover a wide range of solutions for the construction of external walls and internal partitions. The product range includes wall blocks, partition blocks, and structural blocks of various sizes. Such products can only be manufactured through strict compliance with technology, where the autoclave plays a key role. Autoclave processing ensures the required curing of the material, while the natural composition contributes to the environmental friendliness of the finished products.

Thanks to the combination of these factors, increased reliability is combined with cost efficiency, making aerated concrete a popular solution for modern buildings. At the same time, the price of aerated concrete blocks with delivery should be evaluated together with their technical characteristics, which determine the durability of the finish, heating and cooling costs, and the overall long-term advantages of the material.
