KILZ UPSHOT® Aerosol is rated 4.5 out of 5 by 102.
Rated 5 out of 5 by from I love this stuff! As a professional remodeler, I use this stuff all the time. We often encounter roof damage resulting in brown water stains on gypsum board ceilings. These stains often show through fresh paint, even after several coats. Stains are no match for Killz Upshot, though! It covers quickly and completely and after a brief drying period is ready for paint. The aerosol cannister makes for a quicker and cleaner repair and paint prep than traditional brush and roller methods. The aerosol also drips less and covers textured surfaces much more thoroughly than brushes or rollers. It also saves over purchasing of primers in a can, as a single aerosol can of Upshot is enough to cover most stains. For me, Killz Upshot is an invaluable tool to keep on hand for any paint project or roof repair.

Rated 5 out of 5 by from Upshot has great stain coverage I bought some upshot last year when a leaky roof stained the textured ceiling in our bathroom, the upshot covered the stain nicely and is super easy to use

Rated 5 out of 5 by from Worked great! The Upshot primer worked great to cover stains on my 20+ year old acoustical ceiling tiles. Color matched perfectly because it was not a bright white, but a bit off-white. Now I just have to find a ceiling paint to spray over this primer. If this was a primer and paint in one can, that would be the end all.

Rated 5 out of 5 by from Covers Great I bought this to cover a small spot on my kitchen ceiling due to HOA wanting a previous owners satellite dish to be removed. I guess my roof leaked a bit where it was. But now I have a new roof and decided to correct the spot since I knew there would not be any further leakage. The only recommendation is that you cover all areas nearby as there is a dust that comes along with the spray.

Rated 5 out of 5 by from Love it! I have used this product multiple times to cover up spots on the ceiling. I used to use the paint for cover up on ceilings and it was wonderful, but the aerosol spray is so much easier to use and it's a great cover up for spots and water spots. I have also used the paint on my exterior doors. It's the only way I could use just two coats to paint a dark brown door white. Love Kilz products!

Rated 4 out of 5 by from Great for ceiling work I used a couple times over the winter for ceiling. Just wish I had considered how much blow back there was though. It covers well but be sure to cover everything u don't want small dots on.

Rated 5 out of 5 by from Favorite product This it wonderful stuff! I am a messy painter. I had color dabs on the edges of my ceiling in several places from bumping it with a paint brush or rollers while painting. With Upshot it’s totally , easily fixable ! I shook the can , held up some poster board to protect my color , and with light and short bursts made it dismay as if it never was messy. I recommend it to all DIY painters.

Rated 5 out of 5 by from Covers great. One of your reps had pointed it out to us a few yrs ago for work on an income property. Recently we have been doing work on our house to get it ready to sell and the wall and ceiling had mildew stains even after cleaning. Used upshot and then painted and you can't even tell.

Rated 5 out of 5 by from Amazing product My home is over 150 years old. The bathroom that was constructed has no ventilation. Black mildew had accumulated on the ceiling above the shower. This Killz Upshot was a miracle find. So easy to use. I'd highly recommend this product. Thanks Killz!

Rated 5 out of 5 by from Amazing product We had a leak in our roof right as it was to be replaced and ended up with a stain in our daughters room about 12 inches in diameter. I found Upshot at Walmart and thought I’d give it a try. It took one coat to hide the ugly brown stain and it matched the ceiling perfectly. You can never go wrong with Kilz.

Rated 5 out of 5 by from Job saver! I am plugging along in my dining room renovation and had to caulk around some moulding sand trim, grab the caulk gun without thinking it had my silicone caulk already loaded, well, you can’t paint over silicone caulking! With a little research, I got some Kilz upshot to spray over the silicone and viola! It stuck to the silicone and I successfully paint over it no problem! Sure beat pulling and scraping out all of that caulking! Whew!

Rated 5 out of 5 by from Works Great! We had a minor leak in the roof that we had repaired but had still had a water stain on the popcorn ceiling to address. I'd used Kilz in the past in a similar situation with a brush that worked great but when I saw the Kilz Upshot I couldn't resist giving it a try. Wow! Talk about easy! I put down a drop cloth but didn't end up needing it. The design of the Upshot is fantastic... the task was done in less than 5 minutes and you can't tell there was ever an issue. 5 stars!

Rated 5 out of 5 by from OMGahhhh Awesome We had water stains on our ceilings and they were ugly. After roof damage we just couldn’t afford to fix everything from insurance. Went to get ceiling primer from a store and this was all they had. It blended and saved us $200 plus. I don’t have a picture because I’m not at home to upload but it’s an amazing product!

There is no need for you to have to get out a lot of supplies with this wonderful product. Even if you have a can of Kiltz, you should keep this on hand for ceiling repair.

Rated 5 out of 5 by from Works Upside Down! We had extensive roof damage with several leaks that damaged and stained the plaster on the interior of our home after a round of several storms. The tannins from old wood was horrendous. Our home is circa 1900 and we had remodeled the rooms to have cathedral ceilings. Normal painting was difficult and dangerous until we found the KILLZ UPSHOT for the places where it was most precarious. KILLZ UPSHOT hit the places where regular painting was impossible. It worked like a charm! We were even able to turn the can upside down and still spray in some tight spots!

Rated 5 out of 5 by from Perfect coverage We used Kilz Upshot on my mom’s ceiling after her home was damaged by hurricane Florence in 2018. It made covering those nasty water stains so much easier! We will definitely use the Kilz low odor primer before painting when we do our house.

Rated 5 out of 5 by from Super Easy ! I bought this a few weeks ago to paint my son’s bedroom ceiling area where water leaked through from a tree hitting our roof from a storm. The Kiltz upshotz made it easy to spray the ceiling and aim where I needed to aim. Definitely made my life a lot easier.. easy to paint over after it dries too !

Rated 5 out of 5 by from So easy to use! This was the best, I didn't have to rotate the can, bend like a pretzel or stop because the flow was too low due to angle. We used this on a popcorn ceiling with a little water damage and the coverage was great and I could not have asked for easier use.

Rated 5 out of 5 by from Great cover! We had a humidifier upstairs, and the reservoir full of water spilled. The big spill, spilled onto our carpet and went through the whole floor, and went through the ceiling in our downstairs bedroom. It left a whole big yellow stain on our ceiling. We ended up using Kilz Upshot Aerosol and it covered wonderfully. Amazing. We won't have to worry about the yellow showing through anymore!

Surface Preparation

  • The surface must be clean, free of dust, grease, wax, peeling paint, mold, mildew and 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

Topcoat with latex or oil-based paint after 15 minutes.


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.

  • Replace nozzle with valve opening pointed away from you. 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.
