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.

The real deal when it comes to mold prevention!
Would RecommendI liked best the promise this product made to kill mold. I found that promise was not made by any other manufacturers of similar products and was willing to pay a premium price for the Zinsser product.

Mold killer, not a stain blocker.
Would RecommendHave used the "K" brand in the past only to find out it should not be painted over mold. Its only for preventing future mold/mildew. So I tried this "Z" brand mold killer. For mold killing, it does the job. I still cleaned the loose mold with a bleach blend cleaner first, but then went to the mold killing paint once the walls were nice and dry. Goes on pretty thick, but does not really cover. Old light colored paint and remaining mold stains still show through. But I didn't really buy this as a ...

Really great for bathroom ceiling
Would RecommendOur house is old and has 7-ft tall ceilings, which causes moisture issues in the shower. This stuff was great covering the existing mildew/mold on the first coat. I also used on some brown water stains from where our roof was leaking. Unfortunately it didn’t cover those spots even after 2 coats, but for the mold/mildew coverage, I would most certainly recommend.
