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!

Works great

Goes further than further than you think Buy a 2 or 21/2 inch brush to use right out of the can I used it to cover a BIG mess and it covered pretty well

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.
