Private houses are not always finished with siding or other building materials. An alternative to expensive finishing building materials is finishing plaster. It has not such a high price, but due to numerous properties it will help to preserve the appearance of the house. The plaster is applied to stone, concrete, wood and brickwork.
Types of plaster
Modern facade plaster, widely represented in the construction markets, is made using cement and lime binders. It has various properties: water-repellent, X-ray and flame retardant, thermal insulation. The applied plaster can be painted, but its decorative types do not need additional painting.
Decorative types of this finishing material include various fillers :
- marble crumb;
- quartz sand;
- glass crumb.
The condition of the facade of the house, whose walls are covered with plaster, is influenced by temperature changes and regular climatic precipitations. Periodic plastering allows you to maintain the facade of the house in good condition.
In order to maintain the effect of the performed manipulations for a long time, before plastering the facade of the house, you need to choose the finishing material very carefully.
A high-quality building material should have the following characteristics:
- Increased moisture resistance and resistance to various weather phenomena, like rain and snow, high frost and humidity.
- A good quality plaster should allow moisture to drain from the walls of the house. In winter, a certain amount of moisture accumulates under the layer of finishing material. If the material does not have the proper degree of vapor permeability, then all the accumulated moisture remains under the plaster and prematurely destroys the facade of the house.
- High-quality finishing material should have frost resistance. Plaster that does not have this property may crack in the cold, thus leading to premature destruction of the facade of the house.
- Good plaster requires resistance to various mechanical damages.
Finishing plasters with one or several of the listed properties are widely represented on the modern construction market.
Preparing the facade of the house for applying plaster
Preparing for plastering
Before how to plaster the facade of the house, you need to consider the following points:
- You can start work on the application of plaster only after complete or partial precipitation of the walls of the house. This will help prevent cracking of the applied layer of finishing material. Therefore, all construction work must first be completed: building a house, laying communications and waterproofing. Putting plaster is the final stage of finishing the house.
- When finishing it is necessary to thoroughly clean the facades of buildings from various contaminants. The plaster will not be able to lie flat on the contaminated surface, it will fall off from the uncleaned walls.
- Depending on the weather conditions at the time of applying the finishing material, the facade of the wall should be wetted with water. This is especially necessary in dry warm weather.
- Plastering requires special construction tools: plumb, brush, spatula, metal brush.
Plastering the facade of the house
Plastering the facade
Facade plastering is carried out as follows:
- The facade of the house should be flat. In case of strong unevenness, it is recommended to use steel mesh, which allows leveling the surface of the wall for subsequent finishing.
- If the plaster is applied to an already plastered surface, you need to select the finishing material that is most suitable for the composition. At the initial use of plaster on the facade of the house, you should choose a finishing material that is suitable in its properties and qualities to the materials from which the walls are lined.
- Initial cleaning of the facade of the house from pollution is carried out. If they are not there, then you can proceed directly to plastering the building.
- First, sprayed on a façade is applied - a thinner layer of plaster, which will allow the next, denser layer to better adhere to the wall of the building. Its thickness should not exceed 0.5 cm.
- 1-2 days after the initial treatment of the facade, the main “soil” is applied, 2 cm thick. It possesses all the properties inherent in the chosen plaster.
- After a few more days (from 2 days to 2 weeks, depending on weather conditions), the plastered facade of the building is treated with a 0.5 cm "covering" with a finishing coat of plaster.
In a week or two, you can paint the wall or, when using decorative plaster, leave as is. Often, the facade of the building is decorated with notches or strokes applied on not yet frozen plaster. In this case, painting is optional, and the wall decor will be unique.
