Failure to perform crack prevention treatment or improper crack prevention methods can cause wall cracking. Applying mesh cloth is one way of crack prevention treatment, but it is not omnipotent. To perform crack prevention treatment, it is necessary to first inspect and determine the type of cracking, and then perform corresponding crack prevention treatment based on the cracking condition or base treatment condition. Grid cloth is applied to the wall before painting. This grid cloth is mainly used for corrosion prevention and crack resistance. It is used on cement, gypsum, and walls to increase strength and crack resistance. If it is a wall that has not been coated with putty, you can directly apply grid cloth. If the wall paint has been applied, it is recommended to first remove the wall base layer at the crack, roll the interface agent, and then apply grid cloth, apply putty, polish, and then apply Chenyang wall primer and topcoat.
For new houses, there may be slight cracks at the intersection between the beams of light walls and load-bearing walls as they settle. This problem can be treated with kraft paper, but for some slightly larger gaps, grid cloth needs to be used for treatment. For some houses that are slightly older, they are usually brick walls and sand gray walls, which are prone to cracking. When renovating old houses, it is necessary to use mesh cloth on the walls to extend the time for cracking to occur, but it cannot guarantee that it will not crack completely. Modern houses are generally brick or concrete houses, and the occurrence of cracks in these houses is relatively rare. However, if cracks occur, they can be dealt with according to the actual situation. If the strength of the cement mortar on the wall base is relatively low or there is sanding, grid cloth can be used to solve it; If there are cracks on the wall at the junction of different materials, they can also be solved with mesh cloth.
