1. Entry 009Choosing the Right Primer

   • P + E / Product and Execution: When adhesion and stains both matter

     Field practiceIf adhesion fails, remove the failed test coating, investigate preparation, and return to a sound surface. Test a suitable bonding primer.

   • S / Substrate: Identify what you are priming

     Field practiceWhere sound coating remains, the primer must adhere to that coating.

   • P / Product: Match the primer to the problem

     Situation: Glossy doors, trim, baseboards, crown molding, and other difficult finishes · My usual approach: Clean and sand as appropriate, then use a specialty bonding primer when needed. · Selection checkpoint: Verify adhesion; do not assume bonding ability includes stain blocking.
