What Customers Are Saying
Customers overwhelmingly praise this mold-killing primer for its exceptional ability to eliminate and prevent mold regrowth in high-moisture areas like bathrooms and basements. Many report that mold previously returning repeatedly has not reappeared for weeks or months after application. Reviewers consistently highlight outstanding stain coverage—often with just one coat—that hides severe water damage and mold discoloration. Customers appreciate the smooth application, quick drying time, mild odor, and easy water cleanup. A few mention preferring a spray version for hard-to-reach areas, and some suggest a second coat for heavily stained surfaces. Overall, reviewers strongly recommend the product for reliable mold prevention and stain coverage.

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.
