I bought this product 2 weeks ago It actually does what it says it will do with just a little odor and the drying time is really fast. the blocking works great I thought it would bleed through but it didn't at all.

Excellent product
Would RecommendIt’s so easy to apply and yes it works. This is much faster than the paint and brush. It doesn’t have a smell so I sprayed inside on some areas. It dries super quick.

It covered the stain in my pantry ceiling!
Would RecommendIt worked for the problem I had, but the odor was very strong. And I was glad it came in white, which made the choice to purchase easier.
