How to Paint on PVC Board
- 1). Wipe down the surface of the PVC with a clean rag soaked in mix of hot water and mild dish detergent to remove all dirt and oil that could damage the paint's final finish. Dry the PVC boards with a new clean, dry rag.
- 2). Sand the boards with 220-grit sandpaper or a sanding block to create a textured surface for the paint and primer.
- 3). Wipe the PVC with a tack cloth to get rid of particles or dirt created from sanding.
- 4). Apply a thin coat of AquaLoc (the primer/sealer made for plastics) to the PVC with a stiff natural bristle brush. Let the boards dry for about an hour, and then apply a second coat with a foam brush in long, even strokes. Let the second coat dry fully, which takes one or two hours.
- 5). Apply a coat of acrylic latex paint in your desired color/finish with a foam brush, roller or electric paint sprayer. You may need to apply multiple coats.
- 6). If the PVC boards are for a piece of furniture or placed in an area that will see a lot of wear and tear, apply a thin coat of a wipe-on polyurethane varnish to the boards with a clean rag. Follow the directions specified on your particular brand of varnish.
