KILZ UPSHOT® Aerosol is rated 4.5 out of 5 by 80.
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!

Rated 5 out of 5 by from What did I do before this was invented? I was a general contractor for 27 years. If only we’d had this product for renovations and remodeling! It covers completely, even the toughest stains and water marks. The best product ever for tough jobs on ceilings.

Rated 5 out of 5 by from Nooks & Crannies I bought this to do the inside of my 1931 (with original red & yellow paint) kitchen cupboards in my Art Deco Bungalow. My cupboards were odd sized and some were very small, almost too small to reach by hand with a paintbrush, which made Upshot my choice with crossed fingers. I was skeptical at first as I was sure it would not spray at odd angles, but it proved me wrong!! Covered evenly and did a great job, I recommend this to anyone who wants to get inside of drawers & cupboards (furniture as well) to cover seamlessly. Thanks

Rated 4 out of 5 by from Great for water damage The product did 90% of what it said it would. And for the price , totally worth it. It covered an old ceiling water stain nicely. It looks way better than before. But it did not match the rest of the old ceiling. If you’re looking, you’ll def notice it. But a quick coat of paint and there’s been no bleed through as of yet. So I would recommend

Rated 5 out of 5 by from Ceiling Touch Up I used this product to cover up water marks where my daughter spilled water upstairs and didn't clean it up. The water mark made my ceiling look terrible. I used Kilz Upshot Aerosol and the paint blended in perfect with the ceiling that was never painted. I have recommended it to several people and they found the same results.

Rated 1 out of 5 by from Worse now than before! I think we got a bad can or something... the more we sprayed the ceiling, the darker the spot became. After three coats and allowing it to dry for 24 hours, we now have a 24" square brownish, oily-looking patch on our ceiling. So disappointed. I don't know... we shook the can for what seemed like 10 minutes to be sure it was properly mixed before application, too. Good thing it's the garage ceiling. We have another spot in our kitchen - no way I'm using this to cover it!

Rated 5 out of 5 by from Job Well Done. I used this on a leak in my living room ceiling that happened before i got new shingles. It worked great. Just painted over with my ceiling paint and no more leak spot. Also, bathroom door had water spots on it form wet items being hung on door. Painted it and it still showed through. Used the Kilz Aerosol and then repainted. No more spots. Thanks, saved me from having to buy a new door.

Rated 5 out of 5 by from Great coverage I found this product by chance a few years ago. I'm a pro painter and this stuff is AMAZING. I have saved several people from having to do full ceiling repainting with Kilz Upshot. A few weeks back I even used it in my own house for a water stain and it covered completely in one application and matched perfectly. I cant say enough good stuff about it!!

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.
