Finishing the facade of the house of aerated concrete

Many have heard about such material as aerated concrete, but few know about all its properties and characteristics. Under the material refers to stones consisting of silica sand and cement, with pores with a diameter of 1-3 mm. Its decoration has several differences from the usual, so the article will look into this in more detail.

Such material is most often used for the construction of houses. However, its frost resistance is quite low, so for each region it will be necessary to carry out a different facade finish. Next, we learn how to trim the facade of the house of aerated concrete, and what are the possible options depending on the climatic conditions.

Finishing options

First you need to decide what methods of finishing will be most suitable for different places. Thermal conductivity of aerated concrete is comparable to wood.

However, for the construction of houses block aerated concrete is used with a thickness of 37.5 or 40 cm, and logs - about 25-28 cm, as you can see, the difference is significant. Therefore, we can conclude that the heat-saving effect of a log wall will be worse than that of a gas concrete.

Tip: do not confuse aerated concrete with aerated concrete. Both of these materials are cellular, in addition, they are similar in appearance and have the same weight. However, their main difference lies in how they react to contact with moisture.

Foam concrete does not allow moisture to penetrate into itself, but, on the contrary, aerated concrete is quickly filled with water. That is why for the construction of houses in areas where it often rains, it is not necessary to take aerated concrete.

Distinguishing between these two materials is very easy:

1. Dip them in water for a while, then remove them..
2. If the weight remains the same - it is foam concrete.
3. When the weight of the stone has become more, it means that it has absorbed moisture, which means that it is aerated concrete.

Plaster

If you have decided not to insulate the facade of a gas-concrete house, for its finishing it will be necessary to look for special mixtures.

The instruction is simple:

1. First of all, walls need a deep-penetrating primer, after which the facade plaster mix is ​​applied.
2. It is advisable to reinforce with mesh before laying the plaster wall. From this, of course, you can refuse, but the corners, door and window slopes still need to be reinforced.

1. It is important to ensure that the plaster does not dry out. To do this, it is necessary to splash water on it until the solution is completely dry on the wall.
2. Do not perform plastering in frost, but if you really need it, you can use frost-resistant additives that will save the solution from freezing.

Siding

This lining option is well combined with aerated concrete blocks, because Siding does not pass moisture and has high heat resistance. Since the base of the wall does not have high strength characteristics, it will be necessary to mount the framework for this method of cladding.

It forms installation gaps, ideal for filling with insulation, including mineral wool and foam. In addition, they give another advantage - the facade with this type of decoration will be ventilated.

In order for the dowel to be well spaced with a screw, the diameter of the latter should be 1-2 mm less, most often the ratio is: first - 66 mm, second - 5 mm. In addition to diameter, the length of the dowel, which must be at least 50 mm, also plays an important role.

Facing with stone

The main problem when choosing this type of finish is the binding of the main wall and brick. The best option for this is the use of flexible ligaments that do not rust. If you decide to stay on the metal bond, it will first need to be treated with a primer.

The most affordable option for the bundle will be a smooth 5-6 mm A1 fitting. Installation should be carried out at the seams of brick with aerated concrete.

Tip: size mismatch may give you the idea that you need to bend the reinforcement slightly. Such a decision would be wrong, because while its strength properties will decrease.

To fix the reinforcement in the wall, it is necessary to drill a hole, then hammer a metal pin there with a slightly smaller diameter than the drill bit. To get to the seam of a stone or brick, such a procedure must be carried out directly during the facing works.

In addition, you need to worry about the gaps that need to be left in between the insulation materials and veneer. This will help prevent the appearance of various fungi and mold.

Paint textured mixes

The price of this finishing option will be the lowest.

Consider the process:

1. To begin, you will need to add the selected paint to the vapor-permeable putty.
2. Then apply the mixture on the walls with a brush or roller.
3. If the color does not like it, you can use another. Everything is simple and, most importantly, cheap.
4. The resulting seams can be wiped, and for grinding projections use a plane.

Tip: if you know in advance that you will use this type of facade cladding, you can order aerated concrete blocks that have been specially treated.

Filling and painting on a heater

This method can also be called simple. Its essence lies in the installation of foam blocks on the facade, to which putty and paint are then applied. A special glue is used to fix the panels; additional reliability is achieved through the use of dowels having the shape of a fungus.

Tile adhesive is used to seal the seams, after which the entire surface is reinforced with fiberglass mesh. The next step is a putty for aerated concrete walls, for which any type used for outdoor work can be used. For a more aesthetic look, as well as to protect the top layer of putty, after it dries, paint is applied.

findings

In this article, only the basic ways of finishing the facades of aerated concrete houses were presented. At the same time, we didn’t even touch upon the issues related to finishing with ceramic tiles, nor did we talk about ventilation subsystems.

When choosing a material and method of finishing, you need to focus not only on your climate region, or on what facing will be cheaper. It is necessary to do everything so that you can feel as comfortable and as comfortable as possible in your new home. The video in this article will help you find additional information on this topic.
