#468 Perfik Finish is a Professional grade, interior-wood/Sheetrock Primer-Sealer that is recommended for interior trim made of softwoods and MDF as well as drywall. This fast drying product is water reducible, low odor, low VOC, high hiding, easily sanded, but does not produce as much dust as many enamel undercoaters. #468 provides topcoat uniformity by filling the grain of wood evenly. This product is also an excellent product for priming drywall and finishing ceilings. This product’s “dead flat” finish is especially useful on vaulted ceilings such as those found in churches and upper end housing.
