    When should I seal or coat my concrete?

    Your concrete floor should be in good condition and should not contain any loose, chipped (spalled), or cracked areas. For best results, remove all loose material and dust and repair damaged areas before you coat the concrete. If applying to newly poured concrete, allow surface to cure for at least 28 days prior to coating.

    How do I test for presence of moisture?

    If you suspect your concrete could have a moisture issue, apply a 2’ x 2’ sheet of plastic to the floor, tape down the edges with duct tape, and let it set for 24 hours. If water droplets form on the inside of the plastic or if the concrete appears wet (darker in color), moisture is trapped in the floor and it should not be painted or coated until the moisture issue is resolved.

    How do you get moisture out of a concrete floor?

    Concrete 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 (sold separately) to remove moisture from concrete. Repeat the moisture test after using Moisture Stop.

    Should new concrete be sealed? When should that happen?

    Allow new concrete to cure for a minimum of 28-30 days before applying coating. 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.

    Can I use concrete coatings on a basement floor?

    Yes. Concrete coatings may be used in a basement. Concrete must be in sound condition and damaged areas should be repaired. When using the product indoors, 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.
