Verified Purchase
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!
Verified Purchase
good for tight spaces/corners
although the title of the item says mold killer, it is not fungicidal in the formula; unlike in the normal gallon paint buckets. just something to keep in mind. if you for sure want to kill the mold, go with the mold killing gallon paint buckets for this brand.
Verified Purchase
It's the only paint primer that actually can get painted right over mold and kills it other brands. You have to pre-treat the mold first and **** it then paint in primer to stop any regrowth. This isn't all in one.
