The exterior of the house can be decorated with a variety of materials: artificial brick or stone, caricature, paint and others. Aerated concrete is also used as a building material.
In this article we will tell you how to apply plaster on aerated concrete correctly.
Is it possible to apply plaster on aerated concrete?
Yes, you can.
Any constructed object made of aerated concrete does not have a particularly beautiful aesthetic appearance. Therefore, it is better to close the laid aerated concrete blocks with a beautiful facing material, for example, plaster. This is a relatively inexpensive decorative material that is used for cladding buildings both outside and inside.
In addition, plaster performs not only the functions of a facing material, but also a hardener. Despite the fact that aerated concrete itself does not particularly need a protective material, high-quality plaster can significantly extend the service life of aerated concrete blocks by closing the pores in them, thereby reducing the water permeability of the material.
The technology of applying plaster to aerated concrete outside the house
The technology of applying plaster to aerated concrete blocks outside includes the following steps:
- Surface preparation: includes sealing of all irregularities, cavities and cracks, as well as its dedusting and degreasing.
- Surface priming: provides better adhesion of plaster to aerated concrete. Although, not all materials require the mandatory application of a primer. For example, Teknoizosiva plaster has initially high adhesive characteristics, so it does not need a primer layer.
- Reinforcement: this stage includes fixing mesh profiles to all corners of the building and fixing the mesh (after applying the first layer of plaster).
- Application of plaster in 2-3 layers, depending on the type of plaster and the manufacturer.
- Grout or applying a pattern.
When is it better to plaster aerated concrete outside?
Plastering of aerated concrete outside the premises is recommended to be carried out in the warm season after completion of all internal repairs.
It is also often possible to hear a recommendation that it is better to apply plaster about a year after the surfaces dry after finishing work is completed.
