Rated 5 out of 5 by from Covers Oil Based Paint Product works well in covering oil based trim. It really does stick to the surface so you can paint over oil based with a latex paint. I just use inexpensive but decent brushes, that I throw away, because you cannot wash the product out of a brush with water.

Rated 4 out of 5 by from Nice coverage I used this on a wall that had multiple layers of wallpaper that was removed and it made an excellent cover for under the paint. The patches area are barely noticeable. You can tell only if I point them out.

Rated 5 out of 5 by from Mold-Be-Gone! After a very wet and humid summer in Texas, our AC vents began to show black mold growth on the metal vents. We completed a quick soapy wash and then followed with KILZ Interior Primer. No more mold, it hasn't returned and the vents look great - all clean and white.

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® PREMIUM, KILZ 2® or KILZ ORIGINAL LOW ODOR® Primers.
  • Fire Restoration: It is critical to clean smoke damaged surfaces thoroughly before priming.

Application

  • Eye protection is recommended. Do not thin. Stir thoroughly before and occasionally during use.
  • Apply using a brush, roller or sprayer.
  • Use product when painting surface and air temperatures are between 35°F (2°C) and 90°F (32°C).
  • Brush – High quality Nylon/Polyester
  • Roller – High quality 3/8-1/2" nap on smooth surfaces or 1/2-3/4" nap on semi-rough or porous surfaces.
  • Airless spray – .015-.019 tip / 60 mesh filter
  • Prime entire surface to ensure a uniform appearance of the topcoat.
  • Stainblocking: After priming, test for stain bleed-through by applying the topcoat to a small section. If the stain bleeds through the topcoat, apply a second coat of primer and test again before topcoating the entire area. If bleeding continues, a longer dry time is needed before topcoating.
  • Tinting: Up to 2 ounces of universal colorant per gallon. Tinting to a lighter shade than topcoat is recommended.
  • Coverage: 300-400 sq. ft. (28-37 m2) per gallon depending on application method and surface porosity.
