1 gal. Concrete Etch and Cleaner

A:  Happy to help. Slowly add one gallon (full container) of Rust-Oleum Clean & Etch to one gallon of water in a plastic watering can (2 gallons total). Working in a 10x10 foot section of the floor, pour the mixed etching solution out evenly over the surface. Scrub the solution around with a stiff bristle broom. The etching solution will begin to fizz for a few seconds while being scrubbed. When the fizzing stops, rinse off the solution with clean water and move to the next section. The solution should not be allowed to dry on the surface. Mist water on the surface as necessary to keep the surface wet until ready to rinse. When all sections are completed, rinse 3 times with clean water and scrub with a stiff bristle broom while rinsing. This will ensure that no solution remains on the surface. A squeegee will aid in the removal of excess water. If the solution was allowed to dry on the surface, rinse with water and scrub with a stiff bristle broom, then rinse three times. - Rust-Oleum Product Support 6

A:  Happy to clear things up, Simon! Rust-Oleum Concrete Etch and Cleaner can be used to help prep bare concrete prior to coating, painting or staining. Etching helps open the pores of the concrete to ensure proper penetration of the stain. Newer concrete still typically needs to be etched, and etching is typically required on concrete that will receive vehicle traffic. However, you will want to check with the stain manufacture for their prep recommendations. - Rust-Oleum Product Support 3

A:  Thanks for reaching out, Greg. New concrete must be allowed to cure for 28 days before it can be painting. Before apply any Rust-Oleum concrete paint, the concrete (including skim coat) needs to be etched. Rust-Oleum Clean & Etch for Concrete is an excellent choice to both clean and etch concrete. - Rust-Oleum Product Support 6

A:  Great question, Elaine! The Rust-Oleum Concrete & Etch for Concrete is not designed to remove rust stains. We recommend using a rust stain remover specifically designed for use on concrete surfaces to ensure compatibility. - Rust-Oleum Product Support 5
