Zinnser 03688 Covers Up Stain Sealing Ceiling Paint, White

I got this to cover old water stains on the ceiling, and it works perfectly. The spray nozzle points up, which makes it super easy to spray on the ceiling. It does have a pretty wide spray radius, so you need to cover the wall if you're spraying near the ceiling edges. The paint itself is thick enough to cover with one coat, and there is no running or dripping. This matched my ceiling color almost perfectly, so there is no obvious cover up. Just a note, take down your smoke alarm if you're working near it, this did set mine off! It produces a lot of paint mist and the fumes can get overwhelming if you're working on large areas. Fantastic product for a great price, I'm so happy I got this.

This stuff works great and is easy to apply. Always need a can just in case. Covers water stains. Of course, you need to fix the leak problem before using.

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 covered water stains on ceiling fairly well. I had to reapply twice, and can still faintly see them. I’m glad I read another review warning about putting a drop cloth down under it to protect floors/furniture. Even doing this, there was a fine white powder all over the floor and countertops several feet from where I was spraying. Most of it wiped up but there were a few white specks on the floor I had to really work to remove.

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

did not have to replace tiles. Simply sprayed, covered stains well. very happy with this product.
