What Customers Are Saying
Customers overwhelmingly praise this primer for its exceptional mold-killing ability and ease of use. Most highlight its proven effectiveness at eliminating mold and preventing recurrence without requiring pre-removal, with one coat often sufficient. Reviewers consistently commend its smooth application, quick drying, and strong coverage even over dark stains. Many professional painters report long-term success with no mold return.

I was painting on a wood ceiling in a well room. It was a little difficult to use a roller. It dripped a lot. Covered ok after 2 coats.

Works great!
Would RecommendVery happy with my purpose. I had some mold in my bathroom from a water leak. The actual wood was strong and in good shape. I decided to give this a try versus hiring someone to replace the wood. It worked great!! I recommend this product!

Smooth application
This is an unfair review because mold takes time to reoccur once you've cleaned it up. So it's a little hard to put a review but the product went on like it should. Here's hoping it stays mold free.

Great Quality
Would RecommendWe used this in our basement which had a mild mold issue, and there has been no more mold since applying this. This primer covers and applies very well. Most of it was done with a paint sprayer and it went on great.

What a waste
Would Not RecommendModest coverage, but won’t bond well enough to stop painters tape peeling it off. I’m furious

Great fir bathrooms
Would RecommendUsed this in my bathroom in my 100 year old house to keep mold and mildew from coming in on the new bathroom drywall. I have used it over the years and it has covered, and dried great.
