What is the primer?
Latex paint Primer is usually white and has a certain viscosity of the liquid, can be directly applied to the surface of the paint, is the first layer of the paint system, used to improve the adhesion of the finish, increase the finish of the full It is possible to ensure the uniform absorption of the Face Paints, so that the paint system can play the best effect, generally according to the coating requirements can be divided into the first road primer, the second is to improve the finish of the finish, provide anti-alkali, provide anti-corrosion function, Road primer and so on.
Latex paint primer can effectively close the grassroots level, so that the wall base more solid. Some of the wall alkaline strong, after the moisture, water and so on to produce alkaline flowers, scientific name "pan-base", which caused the surface of the film formed a crater-like protrusions, serious in the film surface to form a layer of alkali cream, The final film damage. Latex paint primer can be closed to alleviate this situation. However, if your house wall is relatively dry, and the floor is high, do not may not be a problem, but I suggest you use, so more insurance.
Primer can enhance the adhesion of the finish, improve the adhesion of the latex film and the wall to avoid the wall from the skin off.
Primer can make up for minor cracks, improve the wall flatness, if your wall is more smooth, you can not use the primer, of course, the effect will be better.
