Is it necessary to fix the wall after whitewashing?

It is necessary to solidify the wall after whitewashing. Because this process has good permeability, it can well infiltrate the wall base material, make the base dense through gluing, improve the interface adhesion, improve the bonding strength between the mortar or putty and the wall surface, and prevent hollowing. In addition, solidifying the wall can also test the wall treatment process and whether the workers' puttying and wall paint meet the standards. Whitewashing is a kind of indoor wall decoration in buildings, and it is also the most common type of wall decoration in ordinary houses. Whitewashing is actually to fill the sand holes on the wall and ceiling with a mixture of whitewash powder, talcum powder and cellulose (a chemical adhesive that is easily soluble in water) on the rough cement surface. Scrape and brush white.

Does the wall contain formaldehyde?

1. Wall and floor fixings are green and environmentally friendly products and do not contain formaldehyde.

2. It has strong penetration properties and can fully infiltrate the surface of the substrate, which not only makes it more compact but also improves the adhesion of the smooth interface.

3. At the same time, wall and floor solidifiers are also substitutes for 108 glue and interface agent, and are a kind of high-energy interface treatment material.

Ground cement has the function of preventing sand from running away from the ground. Usually when laying wooden floors or floor tiles on cement floors, the cement floor also needs to be treated at the base.

When to paint the wall

1. Apply wall primer when entering the site: Apply wall primer when the decoration just starts, after the dust and sand are dealt with, to prevent the dust from sticking to the wall primer and causing cracks, bulges, and falling on the surface. If the old wall skin needs to be removed, the wall primer should be applied after the skin is removed. It is recommended to apply the primer after the water and electricity renovation work is completed and before the wall is leveled.

2. Apply wall primer before latex paint: Generally speaking, a layer of wall primer should be applied before latex paint. It not only protects the firmness of the wall base and prevents loose particles from forming on the wall, but it can also completely replace the primer. In fact, even if the wall is painted with wall primer, there is no problem even if it is not puttyed, but it will be better if you put another layer of putty on it.

3. Apply wall solidifier before paint surface renovation: If the wall needs to be renovated, it is also necessary to do wall solidifier surface treatment and protection. After cleaning the original wall paint, you can apply a large area of ​​wall solidifier on the putty layer.
