Rated 5 out of 5 by from Awesome I purchased this a couple weeks ago. I had to remove a peel and stick wallpaper from the 80’s from a bathroom of gypsum board. Of course the removal was horrible even with a steamer. The bathroom is normal size but took days to remove. I had to patch a lot of places and sand. Thank god for kilz. It took 2 coats to cover the inconsistencies but it did. It looks blended and no show through

Rated 5 out of 5 by from Great coverage I purchased Kilz Kitchen and Bath Primer for a hall bathroom. We have been removing layers of wallpaper in almost every room - and surprise no one primed. Kilz has been so easy to work with - we painted another bathroom, the laundry room, the kitchen, and a bedroom for a teenage boy - can't hurt to have extra coverage!

Rated 5 out of 5 by from It's not just for bathrooms any more... I'm a klutz with a paint brush, but my husband is a virtual Van Gogh. We were repainting our laundry room and there was one area that was prone to dampness so he grabbed a can of KILZ Kitchen & Bath primer and went to work. We now have the driest, most beautiful laundry room!! Now if only I could get him to do the laundry! ;-)

Rated 5 out of 5 by from Great primer for my kitchen walls and ceiling. I scraped off the horrible popcorn ceiling and wiped down the walls, applied Kilz Kitchen&bath primer. It went on easily and covered beautifully. The paint adhered just as promised, my kitchen is still beautiful with no peeling or scraped off paint in my future.

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.
