EPOXYSHIELD Garage Floor Coating Faqs

    How do I test for presence of moisture?

    Apply a 2’ x 2’ sheet of plastic (such as a heavy-duty garbage bag or 1 gallon plastic storage bag) to an area of the garage floor. Tape down the edges with duct tape and allow to set for 24 hours. If water droplets appear on the inside of the plastic or if concrete appears wet (darker in color), moisture is trapped in the concrete and the floor should not be coated.

    How do I test for presence of a sealer?

    Drip a small amount of water onto various areas of the floor. If the water beads, a sealer is present and paint may not adhere properly.

    Why is it important to test for moisture or sealers?

    Presence of moisture and/or sealers will prevent the coating from adhering properly and may cause product failure. We do not recommend coating under either of these circumstances.

    My floor is sealed, can I still use this product? What do I have to do if the floor is sealed?

    If your concrete floor is sealed, the sealer must be removed prior to coating. This is best done by using a concrete floor sander. After sanding the floor, perform the test for presence of a sealer detailed above. If water continues to bead, the floor should not be coated. If water soaks into the surface, you may proceed to coat the floor as directed.

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

    If the floor already has paint on it, check for areas of poorly bonded or peeling paint. Remove any loose paint by sanding and scraping. Test the adhesion of the remaining paint on the surface by doing the following:


    1. With a single-edged razor blade, cut an X through the coating and down to the concrete.


    2. Apply a 4” piece of duct tape over the X and press firmly.


    3. Completely remove the tape with one quick pull.


    4. If more than 25% of the taped area is removed with the tape, the original coating is not adhering well, and the floor should not be coated unless all previous paint is removed using a concrete floor sander or suitable paint stripper.


    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.  Before you start, find out how to protect yourself and your family by contacting the National Lead Information Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead.
