Zinsser PermaWhite Interior Matt is a tough, scrubbable paint. It’s the top choice for damp, high-moisture rooms. Think bathrooms, kitchens, laundry rooms, and basements — anywhere with damp, temperature swings, or poor airflow, the main causes of mould.

This tough film resists cracking, peeling, and blisters for up to 7 years. It bonds to old solvent or glossy paint too. As a result, it’s great for sealing flat paint, new drywall, block, and concrete.
