Rated 5 out of 5 by from Really holds up A year and a half ago I found that a bathroom had become engulfed in mold. After cleaning the surfaces in a bleach solution, I primed with Kilz Kitchen and Bath before painting. I haven't had any problems with mold coming through at all.

Rated 5 out of 5 by from Bathroom remodel I was working on a bathroom refresh. I primed both my bathroom cabinet and 4 x 4 ceramic shower tiles. I thought there would be a concern with the paint "sticking" to the tiles but there wasn't. It stuck to the tile without issue. I used two coats. The product was easy to use. Very pleased with the results.

Rated 5 out of 5 by from This is the ONE! I bought this for my problem bathroom. Although I had primed and painted it with some, ahem, unnamed product, my walls and ceiling were riddled with specks of mildew within months. Kilz Kitchen & Bath Interior Primer to the rescue! A painter-friend told me I was nuts to not use Kilz, which, she said, was the best thing she'd ever used. When I applied it, it glided on and didn't stink up the house like the other product. Plus, it made the old stains vanish to the point where I've not seen new mildew in nearly 4 years, and I am sold!

Surface Preparation

The following steps are recommended for product performance.

  • All surfaces must be clean, dry, free of dust, chalk, oil, grease, wax, polish, mold and mildew, loose or 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.
  • Peeling or Checked Paint: Scrape off loose paint and sand to a smooth surface.*
  • Glossy Surfaces: For maximum adhesion, scuff sand the surface thoroughly before priming.*
  • Mold or Mildew Covered Surfaces: Any existing mold and/or mildew on the surface MUST be removed before priming or painting. Wash the area with a mildew remover, rinse with water and allow to dry before priming.
  • Masonry, Brick and Plaster: KILZ KITCHEN & BATH Primer may be used on clean, dry, aged masonry surfaces. New masonry must be allowed to cure (dry) at least 30 days before applying KILZ KITCHEN & BATH Primer.
  • Fire Restoration: Not recommended. Primer Recommendations: oil based primers such as KILZ® ORIGINAL and KILZ® ORIGINAL EXTERIOR or water based primers such as KILZ® RESTORATION.


  • Eye protection is recommended. For spray applications, a small amount of water (no more than 1/2 pint per gallon) may be added. Do not thin for stainblocking applications.
  • Only apply if surface, air and product temperatures are between 50°-90°F (10°-32°C). Stir thoroughly before and occasionally during use. Apply using a brush, roller or sprayer.
  • 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 – .017-.021" tip / 60 mesh filter.
  • Prime the 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: KILZ KITCHEN & BATH Primer may be tinted with up to 2 ounces of universal colorant per gallon. Tinting to a lighter shade than the topcoat is recommended.
  • Coverage: 300-400 sq. ft. (27.87-37 m2) per gallon depending on application method and surface porosity.

Dry Time @ 77°F (25°C), 50% RH
