Zinsser Covers Up Ceiling Paint & Primer

I cannot say enough good things about this product, it did exactly what it promised and then some. I had multiple, noticeable water stains on my ceiling that I assumed would require extensive priming or even drywall work to fully hide. One coat of this paint covered them so thoroughly that you genuinely cannot tell there was ever a stain there. The coverage is exceptional. The stains did not bleed through at all, even after drying, and the finish blends seamlessly with the surrounding ceiling. It goes on smoothly, doesn’t splatter excessively, and dries evenly to a clean, bright white that looks professional and fresh. What impressed me most is the confidence it gives you as a homeowner, no guesswork, no layering multiple products, no disappointment after it dries. This paint is a true stain blocker and a real time saver. If you’re dealing with water stains, discoloration, or old ceiling blemishes, this product is absolutely worth it. It delivered flawless results and made my ceiling look brand new. Highly recommended. I wish I had taken a before and after photo.

This stuff took water stain right out of ceiling. I caught it just in time there was very little puddle on the floor by the time I got to see what was going on it wound up being the air handler in the attic and the drain line somehow got disconnected and I just had a service two weeks ago so obviously he probably somehow disconnected it they came and just glued it back together although I don't know how what they're going to do in the future to clean the drain line out in any case that's problem solved for now I spent about $50 in fiberglass from Home Depot and probably another 20 and this paint right here and it is amazing pain matches the ceiling textured ceiling it's a flat white it's not glossy which The Kills tends to be is more glossy than flat but not this it's more flat than glossy and it works really good so I bought two more of them today to finish the project. And I got one thing of mold spray so I'll pick the old fiberglass up and throw it out and spray the mold spray use the box fan let it air out overnight and let it just finished drawing it's almost dry now but just let it do its thing overnight with that spray and then I'll even put some Thompson's wood sealer on that area where the air handler is at just to make it more safe for the future but in any case I'm glad I'm getting it all done been quite a project This stuff works better color flat white matching ceiling better than Killz. Killz original has a glossy finish. This brand Is covering the killz 3 spots and can't even tell now! So happy. I just bought mold killer(in case) box fan and roll of fiberglass to replace the old. And my brand of ceiling spray problem solved. But don't see any mold only fiberglass got wet which I'll put in garbage, and use my new fiberglass once I spray anti mold spray with fan for 24 hours to dry really good. The heat in attick gets in the 117° F and that's hot. Gotta do at night but best time will be an hour to complete in the am. Coolest temps 6 to 7am, then you have to shower to make sure you got the fiberglass off you so really the morning is a really best time to do it it only takes 30 to 40 minutes at the most all you're doing is removing the old fiberglass putting it in a garbage bag and then spraying that spray and turning the fan on and letting it sit overnight so it dries out real nice and then you would put the new fiberglass on top and you're done and you would have already sprayed the ceiling with the paint which I have already done and it's perfect color

excellent product, does exactly what it says it will. Completely covered to stain with one simple spray. The color is flat white and so it blended well with the ceiling. It was easy to control the spray so it did not get on the walls. It tried quickly and did the job

This worked a lot better than I expected, was even surprised how close it matched my actual ceiling paint. Very great idea. Just be careful it does get paint everywhere!

This spray paint did a great job of covering in one coat a recently patched ceiling crack, matching the original flat ceiling white color exactly. Very useful vertical spray nozzle was easy and avoided any drips.

The drop ceiling tiles in my basement were stained from AC duct condensation. In the past, I've taken the tiles down and brushed on several coats of stain blocking primer. The entire process was very labor intensive and it took hours to cover multiple stains. Then I came across this ceiling spray and decided to give it a try. It's a total game changer! One short spray covered the stain completely. Best part was not having to take down any tiles. It's designed to spray with can upright. I shook can very well before each spray to suspend the pigment solids in the can. I also layed down an old blanket to protect below. The best technique I found is to position can about 12" from stain then give it a short burst while moving in a quick circular motion. Anywhere stains were near the edge of tile, I just slipped a sheet of paper between the tile and frame support to avoid over spray. One coat is all it takes. I was able to cover about a dozen stains in about 20 minutes of work total. Awesome!

I tried the box trick someone else mentioned. I couldn't see where I was painting. I looked at the box and it was clean. I discarded the box and sprayed direct. It covered, coated, matched, looks great! The only problem is, I was working on an area about 2 feet in diameter and going a little larger blending the paint. About the time I was done with one coat, so was the can! Where the texture was damaged will still need mud and perhaps another can. But it looks a LOT better already. Hopefully it's enough for the mud to stick to it now. I think it will be. If so, it will save me from cutting out a section of drywall, screwing in and taping off a new piece, mudding, texturing and painting. No matter how well you do it, you can always tell. With no hard tape lines, I can blend it so you'll never see it. Another hint: you can buy the spray texture in a can. It's messy, but it works. I've never tried it on a ceiling. Once you have a good coat of compound applied dip your trowel and tap to create a rough, messy surface. The messier the better. Avoid large smooth areas. Allow it to completely dry, and sand it down with a block, Not too much, again no large smooth spots. Didn't quite get it? Slap on a little more mud, make a mess and let it dry. Lightly sand it with a block and it'll match perfectly. A coat of paint and even YOU won't know it was there. Don't be afraid to make it bigger, sand it more in some spots, and apply more mud if necessary. I've had areas of drywall that someone else patched, never sanded, painted, and still left a large recessed area. One spot took me a week to get it right, but I can't see it at all now. I look for it all the time, there's even a light shining directly on that spot, it's perfect! A recessed spot will always show, but a slightly raised area will not. I have one where I pretty much destroyed the wall running a power cable for an outdoor security camera. I can "feel" that it's slightly raised. I'm not sanding it down again because it's not visible at all. Be my guest, I'll point it out and you can stare at it all you like, You cannot see it. More importantly, the wife cannot see it, and never did. She has no idea how badly I tore it up trying to fish that wire, and at this point she wouldn't care. The camera is installed, it works perfectly, and the wall looks untouched.

Didn’t like the way it spread unevenly
