A:  We appreciate your interest, Lois! While Rust-Oleum Zinsser Cover Stain Oil-Based Primer will adhere to most surfaces, it is not intended for use on marble. We also do not recommend this primer for use in a tub, as the constant exposure to moisture and humidity will cause it to blister and peel. At this time, we do not have a primer or paint that we can recommend for this type of application. - Rust-Oleum Product Support 3
