About Rust Bullet DuraGrade

DuraGrade Concrete is a high-performance, high-build, superior protective coating that can be applied directly onto concrete surfaces without any acid etching. DuraGrade Concrete has outstanding adhesion to concrete surfaces and is scratch, chip, chemical and UV resistant, requiring no primer, basecoat, or topcoat. This patent-pending formula is low in VOCs providing VOC compliance in all 50 states and is available in 18 standard colors or a custom color option, all with a beautiful gloss finish. Easy to apply by brush, roller, or spray equipment. Ideal for indoor or outdoor surfaces and will protect from hot tire pick up. For decorative purposes, apply our Color Flakes atop the final wet coat of DuraGrade Concrete then topcoat with DuraGrade Clear protective coating to seal the flakes in. For an anti-skid finish, simply add Tread-Tex into the coating which intended for that final coat.
