How to avoid wall peeling when using roller brushes?
The reason why the wall is peeled when brushing with rollers is because the base layer is not cleaned, there are floating dust, stains and paint, the putty is not well bonded, and the adhesion of the putty is poor, or the coating film is insufficient, the substrate The water resistance is very poor. How to avoid wall peeling caused by the use of roller brushes?
Specific steps are as follows:
1. Generally speaking, for non-load-bearing walls, you need to apply cloth. You can try wall cloth and white latex with better texture, or grid cloth. The grid cloth will have better anti-cracking effect.
2. Applying the interface agent can enhance the adhesion with the base layer, so as to avoid the dent and shelling phenomenon that you have ever experienced, and then replace the manual chiseling process, saving a lot of time and energy. What’s more important is to ensure that the interface agent is applied evenly.
3. The walls should be flat. The uneven walls need to be leveled. For the uneven walls, you can try to level the plaster first, so that the error of the wall should not exceed 3 mm. If the internal and external corners are not straight, use plaster to smooth them and straighten them with a support.
4. Choose putty with higher particle fineness and harder texture for mixing. Putty must be batched three times. The first time is usually thicker because it involves leveling. The second and third passes should be thinner, mainly to collect light to make the walls look smoother and smoother.
