What is the role of wall glue

1. Wall glue is an interface treatment agent, which plays an important role in wall decoration. It can not only help consolidate the base, but also help other decorative materials cover the wall. If there is powder on the wall, you can also use wall glue to seal the bottom.

2. Wall glue has excellent penetration properties and can generally fully infiltrate the surface of the wall base material. Through gluing, the base becomes denser, thereby improving the adhesion of the interface. It can also increase the bonding strength between the mortar or putty and the wall, thereby effectively avoiding the hollowing phenomenon on the wall.

3. Wall glue can also help smooth bases improve adhesion, so it is widely used in the bonding construction of wall cloth and wallpaper, making it less likely for wall cloth and wallpaper to have dead folds and bulges. It can also be used in the construction process of "hair-making" the base surface. If you want to use wall glue, make sure that the wall base is hard and there are no obvious stains such as floating dust and oil stains.

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.
