  • Primers enhance paint life.
  • They ensure flawless finishes.
  • Primer lays the foundation for paint material and you can find suitable primers for various surfaces.

They dry slowly and get absorbed into the wood surfaces. New paint varieties wit faster-drying technologies are now available in the market.

B. Masonry Primer

One of the basic reasons for paint chipping is inappropriate pH levels of the wall. Masonry primers are applied to avoid adhesion problems. Direct painting over high pH masonry surfaces is a risky decision.
