It is also called anti-cracking cloth, anti-cracking mesh cloth, etc. Mesh cloth is generally made of fiberglass. In actual construction, some people use cloth instead of anti-cracking cloth. Wall cracking is a chronic disease of home decoration, so many people use it as a magic weapon to prevent wall cracking.
Different materials are used between new and old walls. Generally, they are needed in the following areas: First, the connection between the new wall and the old wall, because the moisture content and basic material of the new wall and the old wall , shrinkage rates are different, and cracking may occur once there is climate change; second, the filling materials in hollow repair areas, slot filling junctions, gypsum board ceiling joints, etc. are different from the original walls. Therefore, anti-cracking measures must also be taken; the third is between walls of different materials, such as a wall made of gypsum board on one side and a wall made of bricks on the other side.
Maybe it's because of their online experience that many novice decorators have formed an unbreakable concept: Mesh cloth must be used on the walls of second-hand houses! In this regard, you cannot rely too much on mesh cloth. In fact, only if the painter's skills are in place and the construction is correct. It is the key to preventing cracking. Moreover, the quality of the original walls of each home also varies, and some old walls will crack even if the base layer is built from scratch.
