Surface Preparation*

  • All surfaces must be clean, free of dust, chalk, oil, 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 INTERIOR/EXTERIOR 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 PREMIUM o KILZ 2 Primers.
  • Fire Restoration: It is critical to clean smoke damaged surfaces thoroughly before priming.


  • Eye protection is recommended.
  • For best results, use when substrate and air temperatures are between 35°F (2°C) and 90°F (32°C). Cover adjacent areas to protect from overspray.
  • Shake can vigorously for 1 minute after mixing ball begins to rattle and often during use. Hold can upright, moving from side-to-side while spraying lightly and evenly about 12" from area being painted. 2-3 thin coats produce best results.
  • Topcoat with water-based or oil-based paint after 60 minutes. NOTE: On some surfaces, spot priming may cause a non-uniform appearance in the final coat. To avoid this, prime the entire surface.

Dry Time at 77°F (25°C), 50% RH

  • Topcoat with water-based or oil-based paint after 60 minutes.

Clean-Up & Disposal

  • Do not stick pins or wire into can opening.
