Cleaning and Storage Clean panels after each use, using burlap or flat, non-scratching tools such as plastic or wood scrapers. While MultiPour HDO panels are factory edge-sealed, it is important that any cut edges or exposed wood be resealed with two coats of a high quality polyurethane varnish. To minimize surface degradation and warping, store panels flat in a protected area and avoid direct sunlight. Surface Repairs Clean any concrete and release agent from damaged area and, using a putty knife, apply a solid coat of polyester-resin based auto body putty. Faces are minimum B grade.
Inner plies are minimum C plugged grade.
