Product Overview

Perma-Guard Mold & Mildew-Proof Interior Sealer is a high performance latex acrylic clear interior sealer that is guaranteed to prevent the growth of mold & mildew on the coating film for five uears. It combines EPA-registered mildewcides with Zinsser’s proprietary 100% acrylic resin system to create a coating formulated to withstand the extreme conditions faced by mold remediation and disaster restoration professionals. Perma-Guard passes severe ASTM D5590 and D3273 testing and is extremely effective in preventing the growth of mold & mildew - even when the coating film rewets. Non-corrosive to metal, Perma-Guard produces a tough, durable finish that resists moisture to improve the water resistance of wood, concrete and drywall, minimizing surface water absorption under wet conditions. Perma-Guard is ideal for use on interior wall cavities, trusses, frame and interior side OSB lumber, unfinished cement block basements and other new or previously painted substrates – new or painted drywall, wood, cured plaster and masonry or metal. Formulated to meet the needs of remediation and restoration professionals, it also is ideal for protecting building materials against the growth of mold & mildew in new construction or remodeling projects.

5-gal. Perma-Guard Mold & Mildew Proof Interior Sealer-DISCONTINUED is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Great stuff Honestly, if you need to deal with a mold issue, this primer is a must. Prep is essential for all paint/repair jobs. In dealing with a mildew/mold issue, Perma-Guard should be a requirement. It goes on smoothly and paint glides and adheres to it as it should.
