Questions and Answers for Zinsser GARDZ 5 gal. Clear Water based Interior Problem Surface Sealer

A:  Happy to clear things up, Emma! Rust-Oleum Zinsser Gardz Problem Surface Sealer is intended to seal problem porous surfaces such as bare or damaged drywall, plaster, cement and cementitious coatings, spackling paste and joint compound, calcimine, stucco, acoustic and texture finishes, and uncoated wallpaper. If just needing to prime bare laminate cabinets, we recommend Rust-Oleum Zinsser Bulls Eye 1-2-3 Water-Based Primer instead. This will help block most stains, as it is a white primer, and promote adhesion. https://www.homedepot.com/p/Zinsser-Bulls-Eye-1-2-3-1-Gal-White-Water-Based-Interior-Exterior-Primer-and-Sealer-2001/100398391 - Rust-Oleum Product Support 3
