Rust-Oleum EPOXYShield Concrete Etch 1 Lb

Rust-Oleum Concrete Etch prepares bare concrete for coating or staining. This citric-acid-based formula is easy and safe to use—indoors or out—and will open up tiny pores within the concrete to allow for maximum penetration and adhesion. Best solution for water-borne coatings. Prevents dangerous acids or fumes; will not harm grass or plants.
