One of the most misunderstood and underappreciated products in the paint and coatings market is a primer. What a primer is designed to do and what is expected of it can be a topic for discussion for homeowners/customers and contractors alike.
A primer is a coating that is carefully formulated to adhere well, fill surface voids, and possibly seal in stains and odors when applied to a surface. Surfaces may be concrete, wall board, various woods, composites, metals, and plastics. A primer that meets the design criteria enables a decorative topcoat to lay out smoother, not flake or scratch off, and generally be more attractive on these surfaces.
