All New KILZ® MOLD & MILDEW Primer is a water based primer-sealer-stainblocker that is specially designed for residential surfaces in high humidity, moisture and temperature environments such as kitchens, bathrooms, powder rooms and laundry rooms. It offers excellent adhesion to both interior and exterior surfaces and provides a sound anchor for paints. The EPA registered active ingredient creates a mold and mildew-resistant film that protects the primer film from mold and mildew growth. KILZ MOLD & MILDEW Primer will block most medium to heavy stains including felt marker, grease, ink, pencil, tannin and water stains. It is a fast drying, low odor, very low VOC formula and is easy to clean with soap and water. Not recommended for floors.

Available in Quart, Gallon, 3.5 Gallon and 5 Gallon containers

Rated 5 out of 5 by from Great for bathrooms! We live in an old farm house and have redone several rooms, one of which is the main bathroom. After pulling everything completely out, we built the room back up, used the mold and mildew primer and it's kept up very well for the three years we've been here. We've also used the cover up primer to prime the paneling before painting it. No issues yet after 3 years!

Rated 5 out of 5 by from Nicotine stain and order control We had bought a house a few years back that was with a heavy smoker. We couldn't get the paint store cover or reduce the smell so we ended up going with this one and it not only hid the stains it also messed the order but we have since moved into a new place and now we have a couple areas that we have a hard time getting the paint to cover without discoloring

Rated 5 out of 5 by from Wonderful coverage! We used the Kilz primer underneath our hardwood flooring project. We tore up old carpet, to find HUGE stains from pets and various spills over the years. We used Kilz to paint the whole floor (subflooring boards of wood) to seal out the old smells and help prevent new spreading of any type of wetness from below the house. We then were able to just put padding down and lay our hard wood floors. No problems! Thanks Kilz!!

Rated 5 out of 5 by from Easy to use, great results! My husband and I have been working to repaint our entire basement. We used KILZ MOLD & MILDEW Primer to coat the walls and unfinished ceiling. The primer gave us such a beautiful finish. We are redoing 4 rooms total (basement pantry, home gym, family room and laundry room/family closet). We will definitely use the same primer on the rest of the spaces!

Surface Preparation

The following steps are recommended for product performance.

  • All surfaces must be clean, dry, free of dust, chalk, oil, grease, wax, polish, 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: This product is designed to prevent mold and/or mildew from forming and contaminating the primer film before topcoat is applied. Although it is designed to be applied directly to mold and mildew prone surfaces, any existing mold and/or mildew on the surface should be removed before priming and painting. This will ensure best results. Wash the area with a mildew remover, rinse with water and allow to dry before priming.
  • Masonry, Brick and Plaster: KILZ MOLD & MILDEW 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 MOLD & MILDEW Primer.
  • Fire Restoration: Not recommended. Primer Recommendations: KILZ® ORIGINAL, KILZ® ORIGINAL INTERIOR/EXTERIOR and KILZ® RESTORATION.

*WARNING If you scrape, sand, or remove old paint, you may release lead dust. LEAD IS TOXIC. Contact the National Lead Information Center at 1-800-424-LEAD or logon on to www.epa.gov/lead.

 

Application

  • 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 MOLD & MILDEW 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

  • Dries to the touch in 30 minutes at 77°F (25°C) and 50% humidity.

  • Recoat or topcoat after 1 hour.
