Surface Preparation

  • The surface must be clean, free of dust, grease, wax, peeling paint and wallpaper paste. If washing is necessary use a non-soapy detergent or a TSP substitute. Rinse well and allow to dry. 
  • Peeling or Checked Paint: Scrape off loose paint and sand to a smooth surface. Sanding or removal of paint containing lead is hazardous.
  • Glossy Surfaces: Use over properly prepared glossy surfaces, scuff-sand to de-gloss and wipe clean before application.
  • *Glossy Surfaces: For maximum adhesion, scuff sand the surface thoroughly before priming.
  • Mold or Mildew Covered Surfaces: Wash the area with a mildew remover, rinse with water and allow to dry before priming.


  • Stir thoroughly before and occasionally during use. 
  • Only apply if surface, air and product temperatures are between 50º – 90ºF (10º – 32ºC)
  • Do not thin or apply at a greater spread rate or build up a visual glaze on the surface. Product is formulated for use at package consistency only.
  • Apply using a brush, roller or sprayer
  • Prime the entire surface to ensure a uniform appearance of the topcoat.
  • If rain or threatening weather is expected within 8 hours, delay applications until dry conditions exist.
  • Never apply product to wet or water saturated substrates or when the relative humidity is above 90%.
  • Not for use below grade or under water.
  • Do not flood coat.
  • Must be top coated within 7 days of application or the surface may need to be re-cleaned. To reduce waste, consult with your retailer or an online paint calculator to determine the correct amount of paint to purchase.

Dry Time

  • Dry Time: KILZ PREMIUM primer will dry to touch in 30 minutes and can be recoated or topcoated in one hour with a latex or oil-based paint. Application at lower temperatures, high humidity or poor ventilation will affect dry time.
