Rated 4 out of 5 by from Easy application and affective I had a slight water leak and it affected the ceiling of my my downstairs. It needed something quick and effective that could prevent problems later minus the mess with application. Well here it is! I was able to prime and then paint the affected area in no time, minimal prep for surrounding areas and done !

Rated 5 out of 5 by from Super useful! When we had opened our new retail location, in a freshly built shipping center, our unit had drop ceilings with acoustic tiles. The roof turned out to have some leaks, and our nice new ceiling developed training through the soft tiles. We brought in can of this product and would walk the store every day or so using it to cover the staining and keep our establishment looking crisp, clean and new much longer than it might have without our diligence and use of this Kilz-in-a-can!

Rated 5 out of 5 by from Awsome coverage?! I bought the aerosol because I have popcorn ceiling and I thought this would be perfect. Why yes it was. The leak was around a skylight and caused brown marks. Kilz to the rescue. Great coverage, blended in and did not damage ceiling. Such great products. I will be redoing my bathroom in a modular and Kilz was recommended as a great primer. Definitely will be using Kilz.. Glad there is now odorless.

Rated 5 out of 5 by from Works perfectly I had a cat that wet the carpeting and it soaked through. So before replacing the carpeting (and the cat after the guilty one died) I sprayed the floor with Kilz. It completely got rid of the odor.

Rated 5 out of 5 by from Awesome for art projects I am in a few paint pouring art groups with a total of about 200,000 plus members. I use this product on canvas art boards. Everyone complains that their canvas boards always warp. Mine never warp because of Kilz Original spray primer. So I always recommend this product when people complain about their boards warping. After posting this about Kilz a lot of people are recommending it to stop warpage. Also we use a lot of record albums. Most labels bleed through the acrylic paint. So Again I recommend Kilz spray primer to stop the bleeding of the labels and also to give the acrylic paint something to stick to on the vinyl records.

Rated 5 out of 5 by from Fantastic product I'm a contractor and time is very important to me. Each day is filled with projects. One recent project was painting over a white brick wall in a basement. The wall had yellow stains from moisture and salts. Normally, I would have scraped the old paint and then set up canvas on the floors gotten a roller etc and spent a few hrs rolling on the paint. Well the kilz aerosol cans took care of this job in about 10 min and it looks fantastic. Plus, since I know it's kilz it will do a great job covering the stains for a long time. Five stars!! Now I'm going to start using the spray cans on other projects.

Rated 5 out of 5 by from Great primer for chalk paint I’m a big believer in the benefits of proper surface preparation before applying the finish coat. After throughly cleaning my stained/ polyurethaned project with TSP, I sprayed a base coat of KILZ Original Primer. My chalk paint project came out great!

Rated 5 out of 5 by from Great coverage for black mold water stains. I have used the aerosole on several projects. It has the best coverage of any primer that I have used to block ugly black water stains. Nothing else had worked before I found this wonderful spray product of Kilz. I like the ease of using the spray rather than having to use a brush. It was so simple to use after following the directions. I first found the aerosol almost two years ago and it has held up very nicely. It has completely covered the water stain without any bleedthrough. I am completely satisfied with this product so I just used it again last week on a different trouble spot. I would definitely recommend this to anyone, for sure. Thank-you for making such a good product. Also, I want to say, I used the gallons of Kilz to cover vinyl wallpaper as a primer and that also was great. Then I topcoated it with paint and it has held up for seven years now. I can't say enough about this product. One coat of primer did the trick.

Rated 5 out of 5 by from The best I had water damage on my attic and stain my bedroom ceiling. My house has popcorn ceiling very difficult to paint. This product was the perfect solution, it blended nicely, cover the stain. Makes the ceiling looks like nothing happen. Absolutely love the product. My only wish is that maybe the trigger should be on the bottom of the can to make it easier to spray upward.

Surface Preparation

  • The surface must be clean, free of dust, grease, wax, peeling paint, mold, mildew, and/or wallpaper paste. 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. Sanding or removal of paint containing lead is hazardous.*
  • Glossy Surfaces: For maximum adhesion, scuff sand the surface thoroughly before priming.*


  • Eye protection is recommended.
  • For best results, use at room temperature. Cover adjacent areas to protect from overspray.
  • Shake can vigorously for 1 minute after mixing ball begins to rattle and often during use. Hold can upright, moving from side-to-side while spraying lightly and evenly about 12" from area being painted. 2-3 thin coats produce best results.
  • Topcoat with latex or oil-based paint after 60 minutes. NOTE: On some surfaces, spot priming may cause a non-uniform appearance in the final coat. To avoid this, prime the entire surface.

Dry Time at 77°F (25°C), 50% RH

  • To Recoat / Topcoat: 1 Hour
  • Longer dry time may be required in cooler temperatures and in higher humidity.

Clean up & Disposal

  • Clear spray valve immediately after use by turning can upside down and spraying until only clear gas is released. If spray nozzle becomes clogged, remove and clean.
  • Do not stick pins or wire into can opening.
  • Clean fresh overspray with mineral spirits or paint thinner. Remove dried paint with paint remover, but test small area first to ensure paint remover does not damage substrate.
  • Please consider donating any unused product. For recycling or disposal information contact your local household refuse collection service.
