Rated 3 out of 5 by from Flakes I purchased this product to help hide stains and odors before putting down new flooring after the Texas freeze and busted pipes ruined the existing flooring. It did hide the stained concrete and masked the odors from those pet stains, but it is already starting to flake and come off. Its only been down about a week. I would rather have a 1 coat product

Rated 5 out of 5 by from Amazing results! I knew painting walls damaged by smoke and nicotine were going to be a challenge. A friend recommened KILZ primer to cover the stains and odor. The results were coat of KILZ, followed by the paint, and the walls look brand new. Highly recommend.

Rated 5 out of 5 by from Covers Smoke Smell We moved cross country during the pandemic to a fixer upper home and were unaware of the smoke smell we’d be dealing with in the home. This Kilz Primer was a LIFESAVER!!! We primed EVERY surface (ceilings, walls, cupboards, etc) and we eradicated the smoke scent and got our house looking amazing. This is an absolute must product!

Rated 5 out of 5 by from Amazing Product! I have never used an oil based primer, but this stuff worked amazing. I used it to prime over deep red for a very light gray. It only took one coat of primer and one coat of the gray to completely color the red. BEST PRIMER EVER!

Rated 4 out of 5 by from Covering frog tape green walls I spent Christmas painting my mom's bedroom which was, for lack of a better description, frog tape green. Took me tqwo coats of Kilz Interior Primer, but I had no bleed through after the second coat and the final top coat of paint went on flawlessly. As a somewhat hysterical side note, when I removed the baseboards, the original color resembled blue painter's tape. lol

Rated 5 out of 5 by from Does the job I have been using Kilz for many years. It covers the areas well as a primer to include grease spots, ester spots,etc. Highly recommend that you use Kilz before trying to cover up stains. It will save you a lot of time and aggravation.

Rated 5 out of 5 by from Great Primer! My walls needed a lot of cover up before painting! This primer did the job and my walls look great! Whoever had the house before my had just slapped a cheap coat of paint on the walls without sanding or priming and it the paint was peeling!

Rated 5 out of 5 by from Surprised at how well this works! I am repainting the walls in our rental house and covering up water damage on the ceiling from a leaky roof. These spots were fairly large and lots of discoloration that I was painting over with a light beige paint. At first I was wondering if the primer would do much good because the consistency seemed so thin. I rolled on two thin layers of primer then painted over that and there is no sign that stains or marks have ever been there. I would definitely use this again and am happy with my results!

Rated 5 out of 5 by from This Product is great! We bought this product in November. Our Florida mobile home was closed from Dec 8, 2019 until our arrival in November 2020. The house was closed up and had an extreme mildew smell and had stains in closets, cupboards and rooms. Your product solved this overwhelming smell and made our return more than habitable.

Rated 5 out of 5 by from Kilz a Life Saver We were so excited about our first house. After we got everything moved in, my husband went in to shower. Suddenly we realized the prior owner was a heavy smoker. The shower water condensed on the ceiling and the yellow nicotine from the ceiling began to drip. Needless to say we "kilted" every ceiling and wall in the house before we painted. Thank goodness for Kilz ( and I give credit to that elderly woman from whom we purchased the house, because anytime we did a "walk- through, there was no smoke smell at all) In closing, Kilz did the trick and helped improve our home.

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.


  • 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).

  • 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.
