Ratings & Reviews for Zinsser CoverStain Interior/Exterior Multi-purpose Oil-based Wall and Ceiling Primer ( 1-quart )

Good coverage and dries quickly

Good coverage

One my project I was painting my bathroom which was a horrible mint green-g...

A Toxic Nightmare That Makes Homes Unlivable

This primer is a toxic nightmare. As an experienced applicator who has used oil-based coatings since the early 1980s, I am not squeamish about standard oil-based paint fumes, but the VOC levels from this product are completely indefensible. Whatever properties it is supposed to impart, I cannot imagine they justify making a home effectively uninhabitable. No amount of ventilation will save you. Aggressive mitigation measures were put in place before application. We completely sealed all air ret...
