Specification of Epoxy Primer Sealer for Concrete Parts

Should the wall surface be painted with the primer or putty first?

Putty is mainly used for filling and leveling. The primer has an anti-alkali effect and can reduce the amount of topcoat. Some people use the primer directly without putty, but the overall effect is not good. The normal process is putty (three times), sealing primer (one time) and topcoat (two times). This way the effect is the best.

Why use a sealing primer?

The function of the sealing primer:

(1) Seal the substrate, penetrate into the internal structure of the substrate, block the capillary pores in the substrate, reduce the number of open pores in the substrate, increase the number of closed pores, inhibit the of paint moisture, and make the uniform. Make the substrate absorb the coating evenly.

(2) The sealing primer can prevent moisture, effectively isolate the alkali from the coating layer, and prevent the alkali from destroying the coating.

(3) Reinforce the loose and weak substrate and strengthen it.
