Creating a beautiful interior in an apartment or house requires a lot of time and labor. Now there are many working methods that turn the exterior of the house into a fabulous work of art. For this you need only knowledge, skill and desire.
Preparatory work before plastering
To work on the facade plastering were carried out successfully, you must check the evenness of the walls before finishing. Tolerance should not exceed 1.5 cm.
- For such a test, a rake of two or more meters in length is used, pre-calibrated by a plumb or construction level. To check the flatness of the walls in the horizontal direction, it is better to apply a rule or a wedge. When applying the rules in different places of the wall, you need to make sure that the tool sticks tightly along its entire length to the surface. If there are gaps between the rule and the wall, they are aligned with a special mixture. However, these areas do not require any mashing or smoothing.
- The wall must have a rough structure for good adhesion with the layer applied after. For this purpose, make the notches a suitable sharp tool.
- If the irregularities have deviations greater than 1.5 cm, then the process of leveling the wall surface is more difficult. In this case, a metal grid is attached to the wall in problem areas, resorting to the help of dowels. A layer of plaster is applied on top of the mesh, and after it hardens, the surface is leveled with a wedge.
- To facade plaster well kept on the surface, you need to get rid of greasy stains on the walls by carrying out activities for degreasing. This procedure is carried out with a 5% solution of ordinary soda. Then the mixture, which was removed fat stains, washed off with a construction brush dipped in clean water.
Note! If buildings were built a long time ago, and brick walls are their foundation, it is likely that in some places the old plaster may flake off. This defect can be identified with a hammer, which you need to easily walk on the old plaster. During this procedure, loose material may fall off, in addition, if you hear a “empty” sound, this means that the plaster has moved away from the base of the wall. This finish needs to be removed. Found flaws should be sealed with a mixture to align.
The surface of the facade, made of porous concrete, foam glass or foam, before plastering must be pasted to strengthen the reinforcing mesh.
It is not recommended to apply plaster on a building that has not yet been fully erected. This is due to the fact that the construction of the structure in the future will still give some shrinkage, which will be more facing. For this reason, it is natural that the facade plaster will crack.
First, given the material from which the walls were erected, you need to choose the right mixture for plaster.
- The first layer, which is called “splashing”, is applied with a plaster of a liquid consistency, and its thickness should be up to 5 mm. It is intended to ensure the proper degree of adhesion of materials. This solution takes about 48 hours to dry completely. The primer is applied at that period of time when the spray layer has already seized, but has not yet completely dried out. If the applied solution is no longer susceptible to any sharp instrument, the quality of the layer is acceptable, and you can apply the primer.
- Then a second layer is applied to the wall, which is more dense and represents a kind of soil. It is intended for leveling the wall surface, and will also perform protective and heat-insulating functions. The thickness of the layer reaches 20 mm. Before applying the layer beacons are installed, which should be guided when performing plastering work.
- In the period up to 15 days comes the turn of the final layer, which is called the "covering". Its thickness is similar to the first and reaches 5 mm. Here, the plaster needs to be compacted and rubbed with a scraper so as not to form gaps. When creating the final layer is chosen method of finishing the facade.
One of the popular ways to trowel the plastered facade of the building with your own hands is surface treatment with the creation of an textured look. To do this, use a variety of wool on rollers, sponges and other tools. The appearance of the surface depends on the nature of the tool, and the time from the moment of completion of plastering and the start of processing.
Plaster, which is composed of lime, can be processed even in a fairly raw state, and the cement surface - only after a long time. To the surface of the wall looked rough, you can walk on it with a metal or rubber brush. There are many more ways to make a plastered facade beautiful, but this is a matter of taste.
