If you would like to paint vinyl-coated particle board furniture, understand a pair of important factors before you get started. First, because vinyl is non-porous, you must condition the surface to accept paint by abrading it. In addition, because vinyl is slick, you must employ a specific application strategy, or you may end up with runs, sagging and brush strokes in the finish coat.
Place the furniture on top of heavy-duty fabric dropcloths.
Clean the vinyl with dish soap, using a coarse brush. Rinse away all soapy residue. Do not oversaturate the furniture, or the water may leak through holes, cracks, or seams down into the particle board. Allow the surface to dry.
Abrade the vinyl by sanding it with a palm sander. Use 300-grit sandpaper.
Wipe over the vinyl with a tackcloth.
Apply a thin coat of latex primer to the vinyl coating, using the 2- to 4-inch latex paintbrush. Do not overapply as this may lead to runs. Allow the primer to dry for two hours.
Wash the paintbrush with plain water.
Pour 1 gallon of paint into the 2-gallon painter's pot. Dilute the paint to promote a smooth, professional-looking finish by stirring in 1 oz. of water. Stir for five minutes with a stir stick.
Apply two thin coats of diluted paint to the vinyl coating, using the paintbrush. Smooth runs as you apply. Allow two hours of dry time between coats.
