Roughening treatment is a construction method, mainly used for wall tile, in order to improve the adhesion of cement mortar and the wall, so that the wall tile stick more firmly, no empty drum, long-term do not fall off. Hair processing is generally used in the following two situations: First, the waterproof layer is attached to the brick, such as after the bathroom is waterproof, the waterproof layer is relatively smooth and can not hang the brick, and a layer of hair processing needs to be done on the surface. The second is to paste bricks on the smooth wall, such as the shear wall , columns, beams and other areas, also need to do hair processing to improve the combination of ceramic tile and wall tightness. There are many ways to Roughening the surface, including cutting a lot of grooves on the wall, using a broom dipped in cement slurry water on the wall, or high pressure water drawing hair. In addition, there are other methods such as mixing cement and interface agent to paint the wall, and then marking vertical strips on the wall with a shovel knife and special tools. The roughening processing is not only used in building decoration, but also widely used in the “cover“ of highway construction to improve the bonding force. At the same time, the wall after brushed treatment can also effectively resist alkali, moisture, mildew, high water resistance, to a certain extent, can protect the waterproof layer, extend the waterproof life. In general, the Roughening treatment is a construction method to improve the roughness of the wall and increase the adhesive force, which is widely used in building decoration and highway construction.
