Features
Ready-made components are being actively introduced for residential building decoration these days. Nevertheless, the external finishing of an aerated concrete home has very little impact on building costs and does not degrade the home’s functional qualities. This is because a lot of artisans are unwilling to put in hanging screens to cover up imperfections and blemishes or to apply the last coat of polish.
It is important to consider that aerated concrete absorbs moisture and lets steam pass through when selecting finishing materials. Furthermore, the blocks don’t require additional insulation because they have a high level of thermal protection.
There are numerous choices, and each has benefits and drawbacks of its own.
Aerated concrete homes need to have their exteriors finished in order to improve their longevity, insulating properties, and visual appeal. Plaster, siding, brick veneer, and specialty paint are the best choices; each has advantages of its own. Siding adds a fashionable, weather-resistant finish, while plaster offers a smooth, protective coating. Brick veneer provides a traditional, sturdy appearance, and specialty paint improves appearance and protection. Aerated concrete houses are strong and visually appealing for many years to come, and homeowners can guarantee this by carefully choosing the appropriate finishing option.
Pros and cons
It is common to read on topic forums that the finishing of a house built of aerated concrete blocks can only have an aesthetic purpose. But this layer not only makes the house look nicer, it also makes it more resistant to moisture and prolongs its lifespan.
But the finishing material has tight specifications, which restricts the selection of the best option. Ignoring them and performing the finishing improperly may result in wall cracking and deformation.
Finishing options
It is crucial to consider that aerated concrete has a cellular structure and throughput when beginning the exterior finishing process. To ensure that the walls "breathe" normally, finishing work must be done responsibly and without deviating from established technology.
Brick
When determining how to finish an aerated concrete house, brickwork is an important consideration. These materials offer numerous benefits, such as:
- High strength and insulating properties.
- Resistance to intense loads and pressure.
- Presentable design.
- Resistance to negative environmental impacts.
Finishing is a skill-intensive and intricate process, though. A novice craftsman will find it difficult to implement because masonry demands flexible connections between the building material and bricks in addition to beautiful connections between each block. It will be difficult to attain such outcomes without the necessary experience.
Brick finishing also broadens the scope of facade decoration, enabling you to execute any design concepts and schemes. Additionally, they will all appear exceptionally elegant and graceful. One drawback of bricks is their higher cost.
You may want to think about finishing with bricks and applying an insulating layer if the building is in a northern location or if more thermal insulation is required. To do this, the cement-concrete mixture is supplemented with a unique heat insulator. Vermiculite or perlite are used in its place.
Siding
Siding is the best option if you want to cover your home with dry technology. It can be made of cement, wood, metal, ceramics, or plastic. Another intriguing choice is the block house. Siding is the best and most cost-effective option if you need to sheathe a room without introducing complicated technologies.
Every kind of finishing has benefits and drawbacks of its own. Therefore, the option built of metal, cement, and ceramics offers complete fire protection, and the variety of vinyl options increases the decorating possibilities.
Wooden siding satisfies all environmental requirements while maintaining the elegance of the elite wood structure. It is actively used to finish an aerated concrete bathhouse because of these qualities.
Ventilated facades
Particularly in demand are facades with ventilation apertures. Properly aligning rooms with them according to gas silicate blocks will make them visually appealing and weatherproof. An additional comparable choice lowers heating expenses by guaranteeing even thermal energy distribution and enhancing room heating. It is only permissible to use vapor-permeable materials for ventilated facade insulation.
Apart from mineral wool, a moisture-repellent membrane that permits steam to flow through must be provided. Its job is to efficiently expel condensation and moisture outside.
Polystyrene foam cannot be used as insulation because it obstructs airflow and prevents water vapor from being removed. Well-insulated facades also provide good sound absorption.
The appearance of the room is altered by cladding, which can be modified to suit the needs of the homeowner. The façade has a stated service life of seventy years, and installation can be done in any weather thanks to "dry" technology.
The following fasteners must be used to secure a ventilated facade:
- Spring dowels.
- Universal dowel nails.
- Chemical anchors.
- Mechanical anchors.
Plaster
Plaster serves as more than just a foundation for tile installation or ventilated facades. When used properly, it can have a decorative effect that presents the space in an attractive and refined manner.
You can use a particular kind of facade plaster for this. Acrylic compounds are known to hold their performance advantages for an extended period of time. They do, however, require more fire protection because they are flammable material.
Plaster with silicone is the original solution. There’s a good selection of textures available for purchase, but not so much color selection. Use of the material is not advised in environments with high levels of dust and dirt. Gypsum is known for its quick drying times, lack of shrinkage, and ability to decorate with just one layer.
Furthermore, stains frequently cover the plaster’s surface, necessitating painting over them.
Painting
You can use a paint and varnish combination to finish the outside of the house. It comes in two varieties:
- With reinforcing and textured fibers.
- With relief components.
Both kinds are applied to the wall using a basic roller and no sophisticated methods or equipment. The final layer has a matte sheen, and additives are used to change the tonality of the layer. Seven years is the stated service life; beyond that, new paint will be required.
Such a layer stops cracks from forming, and the problem of an unpleasant smell is resolved because there is no organic solvent present.
Use a float to remove any dust or small irregularities from the surface before applying paint or varnish. Painting is done on the putty right away.
Clinker tiles and porcelain tiles
It’s important to take clinker and porcelain tiles into consideration when selecting materials for a ventilated facade’s external finishing. Such solutions are very attractive to look at and are relatively easy to install.
One of the drawbacks of clinker tiles is their small size, which makes installation take longer. It is advised to mix the material with ornamental plaster to lessen it.
Porcelain stoneware installs considerably more quickly and is larger than tiles. A metal or wooden lathing can serve as the frame, offering adequate ventilation.
Porcelain stoneware is fixed to a metal profile frame if it is required to add a heat-insulating layer. It is fixed between slab insulation.
Wet facade technology
Regarding original finishing options, wet facade technology must be taken into consideration. It offers the following benefits:
- Increased thermal conductivity properties.
- Improved noise absorption.
- Wide selection of design options.
- Masking of butt joints.
The following components make up the facade structure:
- Heat-insulating material.
- Reinforcing mesh.
- Plaster layer.
This technology is affordable and easy to use. It can be applied to prolong the building’s service life and maintain the main benefits of aerated concrete blocks.
Selection criteria
The exterior finishing of the house facade can be accomplished using a wide range of materials and technologies. All coating manufacturers, however, make an effort to persuade consumers that their product is superior to all others. To prevent errors during the selection process, the following materials are not permitted to be used for final work:
- Sand or concrete plaster.
- Expanded polystyrene and foam plastic.
- Covering paint.
Simple black self-tapping screws cannot be used as a fixation method. Dowel nails are preferable since they don’t form cold bridges and don’t mind absorbing moisture. Aerated concrete bathhouses require vents to be present in the lower portion of the masonry and to be closed off with a protective grill when brick finishing.
Successful examples and options
You should examine photos of the most effective options and examples to find the best finishing options for your space. It’s advisable to seek advice from friends or neighbors who have finished finishing an aerated concrete building. Using the examined examples as a guide, you can select a suitable option for your house.

Aerated concrete homes require finishing as a critical step that improves the home’s visual appeal and offers vital weather protection. There are many options available, so it’s critical to select the one that best meets your requirements and tastes.
The most common options are brick veneer, siding, and plastering. Plastering can be customized with various textures and colors and provides a smooth, contemporary finish. Siding offers a low-maintenance, long-lasting alternative that can imitate the appearance of wood or other materials, whether it is fiber cement or vinyl. Brick veneer improves the aesthetics of your house while also providing additional insulation.
Every finishing choice has advantages and disadvantages of its own. Plastering needs to be maintained frequently to avoid cracks, whereas siding may be more weather-resistant but may require periodic repainting. Brick veneer is more expensive to install but is more durable and long-lasting. It’s critical to consider these aspects when choosing a choice.
The ideal finishing technique for your aerated concrete home ultimately depends on your spending limit, the style you want, and the local climate. You can make sure that your house not only looks fantastic but also endures for many years by giving these factors careful thought.
