What Customers Are Saying
Customers overwhelmingly praise this mold-killing primer for its exceptional effectiveness, with most reporting visible mold elimination after a single coat that doesn't return—even in bathrooms and basements. Reviewers highlight smooth application, quick drying, and excellent coverage that often eliminates the need for multiple topcoats. Many note improved mold allergies and appreciate that it works directly over existing mold without complete removal first. While the odor is noticeable, most find it tolerable compared to harsh alternatives. A few mention adhesion issues on certain surfaces or wish for smaller sizes, but overall customers consider it a reliable, time-saving solution.

Would RecommendWhat is there to say? It's primer with stuff added to kill those nasty mold and mildew spores. Win/win.

It actually works.
Would RecommendIt covered the mildew in the bathroom. My wife is very sensitive to mold and mildew. We purchased this to see if it would help her from closing up all the time. It worked. She feels much better.

Make sure space is well ventilated
Would RecommendWe had some mold on the bathroom ceiling that grew while our exhaust fan wasn't working well. This easily covered the stains in 2 coats. Easy to roll on as it is just the right thickness. It has been 2 weeks and no mold has reappeared.

Great Coverage!
Would RecommendGreat coverage. I cannot speak for the mold killing aspect of this product but I used it over some crappy walls (perhaps a little mold or mildew) and one coat was enough and no bleed through. My final coat only needed one coat as a result. Check the primer on the right and the right and final coat on the left.
