This paint far exceeded any expectations I had. the coverage is outstanding, i used this on a bathroom vanity and one coat was plenty and hid the paint underneath completely. It worked so well i was able to use it for multiple projects around the house, with a minimum of two coats of paint, with some to spare.

Trusted brand

I have used Zinsser Primers for decades %26 they always have work as expected. Zinsser primers are easy to use, the stain coverage is good, etc. Make sure you read %26 follow the directions %26 you won't have a problem. I bought the Mold Killing formula this time because I have a few closets on the outside walls that have some superficial mold on the corners after our cold winter combined with higher humidity in the house. I don't expect any issues with the mold coming back or recurring staining now that I have used the mold killing primer. I don't usually have mold issues, but had some work done %26 the air exchange wasn't set up completely accurate for the changes made. I don't expect any more mold issues either. I have never had old stains or paint colors come through the Zinsser primers in the past either. I definitely recommend any of the Zinsser primers %26 their other products.

it covered beautifully with the existing ceiling, although it was in a bathroom with no natural light. BUT it covered and matched very well my ceiling in my condo at the beach. wish there was a way to collect the spray particles that fall all around. Otherwise i like the product a lot!
