Wall cracking? Don't let real stone paint back 'black pot'!

Today Xiaobian will show you the "black pot" on the back of real stone paint!

1. The facade defects of building wall lead to the cracking of decorative surface

Some quality problems of wall itself, such as hollow wall, shrinkage of material after immersion leading to cracking of external paint. Solutions:

If it is a problem of the external wall base itself, only along the direction of cracking, evenly remove the empty wall, it is suggested that the elastic putty be used as the base, and then leveled as a whole. Finally, the application process of real stone paint coating on-line coatingol.com is carried out.

2.If the putty of true stone paint is too thick

true stone paint, the putty layer must be scraped before construction. If the putty is scraped too thick in a single batch, the drying will be uneven, and then the continuous cracking will occur. Most of these cracks occur at the intersection of Yin and Yang angles and walls, where it is difficult to achieve complete smoothness.

Solutions: It is very simple to solve the cracking of putty layer, only need to polish the putty unevenly, and then use putty for simple repair.

3. When the plastering layer of cement mortar cracks

surface is plastered, the cement mortar is batched without drying thoroughly, which causes the cement mortar to crack after drying thoroughly, resulting in latex paint cracks after finishing decoration.

Solutions: In this case, if the wall cracks need to be remedied, it will be relatively troublesome. If irregular cracks occur on the whole wall, it needs to be removed and re-constructed.

4. When the coatings have been cracked

Primers and topcoats are painted, the construction of the back passage begins before the paint is completely dry. The inconsistent shrinkage leads to the stress distortion of the joint surface and the cracking of the topcoat. Solutions:

If only the cracks of the surface paint film are cracked, the cracks are polished off with fine sandpaper and re-painted.

5.What should we do if there are large area cracks on the wall which can not be repaired locally?

Solutions:

The first way is to scrape the cracks first, then scrape them again with putty, so as to prevent the wall from seeping again and entering ash.

The second way is to seal with special paper tape, and then seal the edge again with viscose yellow tape, and then paint after drying. This can effectively ensure the stability and stability of the foundation layer and avoid the intensification of wall cracking. The cracking of wall base surface belongs to structural cracking. Repairing can only maintain the surface effect without severe influence. Once the wall fluctuates or displaces, cracking may be aggravated. Therefore, in order to achieve permanent effect, structural construction problems should be avoided.

There are many reasons for the cracking of real stone paint. Apart from the quality problems of the house itself, the wall cracking is more a problem caused by the non-standard construction. The problem of paint has been decided at the beginning of the user's intention to purchase. Therefore, when engineering users select coatings, they should pay more attention to supervising and examining the wall construction technology, "material" and "worker" grasp both hands, both hands should be hard, so as to solve or even avoid the cracking of real stone paint in advance.
