When dry, Gardz may be top coated with any standard architectural water-based or solvent-based primer or topcoat paint. Gardz is compatible with all types of joint compounds and spackling pastes and any texture or popcorn finish may be applied over it. Any surface that has been coated with Gardz is suitable to be wallpapered directly over. However, some types of wallpaper and translucent wallcoverings may require an additional coat of an opaque primer.
