    What if moisture is detected?

    RockSolid® Polycuramine® Garage and Metallic Floor Coatings are not intended for use on floors with a moisture problem. If moisture is present in the surface, it will affect the adhesion of the product. If moisture is found after completing the moisture test, use Rust-Oleum® Moisture Stop (Item #301239, sold separately) to remove moisture from concrete.Repeat the moisture test after using Moisture Stop.

    What do I have to do if my floor is sealed? How do I test for presence of a sealer?

    To determine if your concrete is sealed, drip a small amount of water on the floor.  If the water beads and sits on top of the concrete, a sealer is present.  If the floor is previously sealed you can use Rust-Oleum Recoat Primer.  It allows you to recoat a sealed or coated surface without having to sand or grind the floor.

    My floor already has paint on it. Can I apply RockSolid over another coating?

    Existing floor coatings need to be in good condition with proper adhesion to the concrete substrate. Check the adhesion of the previous coating by cutting a small X in the coating using a sharp razor knife. Firmly apply a piece of 5” duct tape over the center of the X cut, and then pull off with a fast snap. If more than 10% of the taped area is removed, the original coating is not bonded well and needs to be removed chemically or mechanically with a grinder before applying RockSolid® Polycuramine® Floor Coatings. If the coating is firmly adhered, scuff sand previously painted or coated floor using 60-80 grit sandpaper prior to coating. 

    RockSolid® Polycuramine® Floor Coatings are not intended for use on unsound previous coatings or floors that have a moisture problem. 

    WARNING! If you scrape, sand, or remove old paint, you may release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a NIOSH-approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop.

    Can I apply RockSolid on new concrete?

    Allow new concrete to cure for a minimum of 28-30 days before applying RockSolid® Garage Floor Coatings. Sweep away all loose dirt and debris. Remove any oil spots, grease or spills and wash the floor with a suitable detergent or degreasing solution and rinse. Then etch the floor using the Concrete Etch supplied in the kit.

    Can I use RockSolid® in a basement?

    RockSolid® Polycuramine® Floor Coatings may be used in a basement. Concrete must be in sound condition and damaged areas should be repaired. When using the product indoors, the enclosed concrete etch is not required. Instead, ensure the area is clean and free of dirt and dust, or rinse with water and allow to thoroughly dry prior to coating. Follow all other product installation and application instructions on the packaging.
