How can we completely eliminate the problem of wall flooding?

Before the construction of latex paint, the grass-roots units must be treated. For the new cement wall, you can scrape it off with flat-bottomed cement slurry or water putty, and then brush it after drying. For old walls and powder walls, the surface should be thoroughly cleaned, dry and flat. The method is to scrape off the loose and fallen surface substances with a wire brush, polish them with sandpaper, and then construct them according to the new wall method. For the old walls that have been sprayed with color spraying or other brand paints, the surface materials should be removed first, and then the construction should be carried out according to the procedures of the old walls. The surface treatment method of wooden base is the same as that of cement wall.

When brushing different brands of latex paint, the basic treatment methods are slightly different. Please pay attention to reading the instructions.

Latex paint should be painted with primer first, and then with topcoat. Primer is chlorinated rubber product, which has strong waterproof and alkali resistance and excellent penetration, can greatly improve the adhesion and durability of paint film and base course, provide a solid foundation for topcoat, and prevent paint surface from discoloring due to alkali corrosion.
