Simple building, the wall wants to scrape putty instead of latex paint, I don't know if it's ok?

You don't need to brush latex paint, which will lead to powder loss.

Putty can be used as a thick slurry coating for decorating walls, and it is a necessary product before painting. It consists of a small amount of additives, paint base, a large amount of fillers and a proper amount of color pigments.

The main pigment products used are carbon black, iron red, chrome yellow and so on. It can be used to fill the local depression of the working face, or it can be scraped on the whole face. Usually after the primer layer is dried, the surface of the primer layer is scraped off.

Precautions:

1. Base treatment: For the cast-in-place concrete wall, due to the ground, materials, isolation agent and other reasons, the flatness of the wall is poor, and there are often phenomena such as air holes, honeycombs, pits, uneven angle of yin and yang, arching, etc., so it is required to smooth it with a convex pick and fill it with a concave surface.

For precast concrete floor slab and floor joint base, the floating sand, pimples, dust and other sundries on the surface must be cleaned by special personnel with wire brushes. The grey surface layer used for cement mortar paper reinforcement requires that the surface base is dry and the solid is clean (the surface is free of oil pollution).

2. Foundation maintenance: After the joints of concrete roof panels are cleaned, the defective parts such as honeycomb are filled with plastering putty with a steel scraper, compacted, leveled and scraped once (the smooth top surface cannot be scraped).

3. The proportion (weight ratio) of gypsum putty is gypsum: emulsion: cellulose aqueous solution (concentration 5 = 100: 5 ~ 6: 60). Sodium hydroxide solution brush: brush with 5 "degree sodium hydroxide solution twice, and brush with 10" degree sodium hydroxide solution 1 time. Use a brush, rinse with clean water, and dry before proceeding to the next step.
