Ratings & Reviews for Zinsser Mold Killing Half Pallet Interior/Exterior Multi-purpose Water-based Wall and Ceiling Primer ( 5-gallon )

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.
