Most families will paint the walls when they decorate their houses. Some houses will be painted when they are renovated. However, some houses need to be repainted, which is called the old wall painting. This requires skill. So what are the techniques for painting old walls ? What are the precautions when painting old walls? If you want to know, just take a look at the small series of the decoration home network.
First, the old wall painting skills
1. Generally, non-load-bearing walls such as light-weight walls and thermal insulation walls need to be patched. Try to choose a wall cloth with a better texture and white latex. If there are conditions, you can use a mesh cloth. The relative crack prevention effect will be better. .
2. Old houses or second-hand houses will inevitably have cracks, so the old wall decoration should pay attention to the cracks. In general, we need to attach kraft paper and mesh to the cracks in the wall and the joints between the light-weight wall and the load-bearing wall. These materials are used to repair the cracks, otherwise the effect of brushing out is definitely not ideal.
3. In the process of brushing the lime slurry, the lime slurry should be continuously stirred. Otherwise, the lime slurry will precipitate, and there will be different stripes on the wall after brushing. When painting, you should master the principle of top-down, one-piece set, vertical brush, or left-to-right cross-brush, but you should pay attention to it.
Second, the main points of the old wall painting
1. In the process of repairing, if it is not comprehensive, and the painting process has already been done, it will be quite troublesome. If the painting is completed, it will be difficult to repair the repaired area. The biggest problem with the expected effect is that it will cause the problem of chromatic aberration, so be sure to be careful and comprehensive when repairing, and don't burden the later projects.
2. Use a tile cutter or a chisel to poke a hole in the wall. Due to the previous level of house construction and economic reasons, the walls of old rural houses are not very flat. At that time, building a house liked to use a hanging cone, unlike the current laser level. Some rural old houses are brickwork themselves. When there was no powder on the wall, it saved a process.
3. The primer must be brushed evenly to ensure that every part of the wall is brushed. If the wall is coated with a large amount of paint, it is best to add a little more water to the primer to ensure uniform coating. Do not think that it is a roller with a little primer because it is a primer. The effect of the primer will directly affect the effect of the topcoat. Use the same texture roller as the topcoat.
