#479 Easy Prime is a professional grade, high build vinyl acrylic latex coating that is designed for use as a primer/sealer on wallboard surfaces. Unlike most primers, #479 goes on in a heavy bodied film which makes it sand exceptionally well, as well as allows it to minimize surface imperfections and irregularities. #479 has good sealing properties and enamel hold out. #479 is high hiding, fast drying, low odor, low VOC*, and will provide an excellent surface for topcoats to adhere to. This product can be topcoated with either latex or oil-based products.
