AFM Safecoat Hard Seal is a multi-use, clear gloss sealer specially formulated to provide mar-resistance to both low and high-porosity surfaces. Hard Seal can also be used on painted or stained woodwork or on unfinished wood products such as plywood, OSB, chipboard, MDF, Masonite, etc. To quote from AFM's technical data sheet " HardSeal may be applied over existing paints, stain and colorfast wallpaper. When applying to a previously coated surface test in inconspicuous places for satisfactory appearance."
