Mold Killer & Easy to Use

This Zinsser mold-killing primer works incredibly well! It effectively stops mold and mildew while providing a smooth, durable base for painting. The application is easy, and it dries quickly with great coverage. Perfect for bathrooms, basements, or any area prone to moisture. Plus, it helps prevent future mold growth, which is a huge plus. If you need a reliable solution for mold-prone surfaces, this is a must-have

Works but mold does come back

We covered our walls with it and it did DELAY the mold from coming back, but it did come back, just took a bit longer than expected. When it's on sale it's worth the $ to keep repurchasing, but when it's at $25 I feel it's way too expensive for a tiny can. I needed to buy two of these to cover the walls of my tiny bathroom.

Great paint great price

I recently bought this paint to help with mold that was building up on the ceiling of my bathroom I just need to say that it's great! I didn't have to use too many coats of paint to cover up the mold stains and it does not smell bad like other paints so you don't need to wear a mask or anything while painting best thing too does not take long to dry and air out just a couple hours definitely recommend

Not useable

The can is fairly small, so if you have a large area to do buy bigger. 2nd when I opened this is was hard inside would not mix at all. So, I dunno if it works since I wasn’t able to use it! It was sealed well. That’s about all I can say.
