  1. Clean the surface

    Before applying liquid sandpaper, the surface should be free of any dust, dirt or grease. Wash it using warm soapy water, and dry with a lint-free towel. Use a tack cloth to remove any remaining dust before applying the product.

  2. Provide adequate ventilation

    Liquid sandpaper is flammable, so provide adequate ventilation before opening the product. Extinguish any open flames, and avoid using the product in enclosed spaces. Wear rubber gloves and eye protection.

  3. Apply the liquid sandpaper

    Use a paintbrush to apply the liquid sandpaper to the surface you want to degloss. Do not spill the product on other surfaces. Allow standing time as per the manufacturer's directions.

  4. Rub the liquid sandpaper into the surface

    Use a lint-free towel to rub the liquid sandpaper into the surface you are deglazing, and allow it to dry. Ensure all the product has evaporated thoroughly before you start to apply the new finish. Make sure any towels used in this process are thoroughly dry before disposing them.
