Questions and Answers for Zinsser Cover Stain 1 qt. White Oil-Based Interior/Exterior Primer and Sealer

A:  Happy to help, Joey! For the best results, we recommend avoiding spraying Rust-Oleum Zinsser Cover Stain Oil-Based Primer in direct sunlight. This can cause dry spray on the surface. Working in a shaded or covered area is ideal on sunny days. - Rust-Oleum Product Support 3

A:  That's not what we expect to hear, Pat! The listed dry time of Rust-Oleum Zinsser Cover Stain Oil-Based Primer will be affected by cooler temperatures, higher humidity, or heavier applications. Please keep in mind, this primer will not reach full hardness until after 7 days in ideal conditions, and we recommend avoiding scratching or abrading the primer before that point. If the primer does not feel like it is drying more, please give us a call at (888) 855-1774 for further assistance. - Rust-Oleum Product Support 3

A:  Hi Jenn, our Zinsser Cover Stain Oil-Based Primer adheres well to ceramic tile, and may be used for interior or exterior applications. Keep in mind that this primer is not recommended for use on floors, so if the tile is on a floor, we would not recommend this primer for that surface. We currently do not offer a primer or coating for exterior tile flooring. - Rust-Oleum Product Support 2

A:  Thank you for reaching out! Our Zinsser Cover Stain Oil-Based Primer may be tinted towards off-white and pastel shades by adding no more than 2 oz. of universal colorant per gallon.
