Surface Preparation

The following steps are recommended for product performance.

  • All surfaces must be clean, free of dust, chalk, oil, grease, wax, polish, mold and mildew, loose peeling paint, rust and all other foreign substances.
  • If washing is necessary, use a non-soapy detergent or a TSP substitute, rinse well and allow to dry.
  • Glossy Surfaces: For maximum adhesion, scuff sand the surface thoroughly before priming.*
  • Peeling or Checked Paint: Scrape off loose paint and sand to a smooth surface.*
  • Mold or Mildew Covered Surfaces: Wash the area with a mildew remover, rinse with water and allow to dry before priming.
  • Masonry, Brick, Stucco and Plaster: KILZ® ORIGINAL Primer may be used on clean, dry, aged masonry surfaces that have cured (dried) at least 90 days. If masonry has cured less than 90 days, use KILZ® 3 PREMIUM, KILZ 2® ALL-PURPOSE or KILZ® ORIGINAL LOW ODOUR™ Primers.
