What is the technology of wall roughening treatment?

The brushing treatment of the wall surface is a plastering standard, and there are two appearance requirements for the plastering of the wall surface: one is calendering, and the other is roughening, in fact, it is to sweep the cement slurry before plastering the wall surface.

Only waterproof walls that need to be tiled need to be brushed, and other parts can be brushed. Walls that don't need to be brushed can be brushed with a layer of interface agent. If all the walls are removed (including the living room), the brick wall needs to be plastered as a whole. If it is a concrete wall, only the uneven parts can be filled up. If the surface is uneven, it is recommended to plaster it again. Brush the walls if they are light. If you stick it, you won't brush it.

Precautions:

1. In the process of napping construction, if it is found that the coating adhesion is poor and the size, length and shape of napping do not meet the requirements, then the napping treatment will fail. Therefore, in the configuration of napping coating, materials with strong aggregation and good thickening effect should be selected to pull out the top coat film that meets the requirements.

2. It is still required that the coating has good anti-aggregation during the napping operation, and the viscosity of the coating cannot rise too high because of the time interval, which requires the coating to have a long drying time. This goal can be achieved by using a thickener with good water retention such as hydroxyethyl cellulose and an additive such as propylene glycol.
