How to Refinish Arborite Countertops
Durable, easy to clean, fire-resistant and available in a variety of styles, Arborite is a favored type of countertop laminate among many homeowners. Over time, however, Arborite can become faded or outdated. Fortunately, it is possible to refinish Arborite with paint. Arborite is made from a combination of paper and melamine, which is a type of plastic, and requires paint specifically formulated for use on melamine.
Wash the countertop with a general-purpose cleaner.
Sand the entire countertop with 200-grit sandpaper. Use an orbital sander, if desired. Sand until you have a consistently dulled and abraded surface. This will ensure proper adhesion of the new finish. Wipe away all residual sanding dust with a tackcloth.
Paint the countertop with melamine primer and a paintbrush. Allow the primer to dry.
Sand the primer lightly with 400-grit wet/dry sandpaper and wipe away the dust with a tackcloth.
Examine the coat of primer for any areas where the original countertop is showing through. Touch up those areas with primer and a brush as needed.
Paint the countertop with melamine paint and a paintbrush, using a color of your choice. Allow the paint to dry.
Sand the paint lightly with 400-grit wet/dry sandpaper and wipe away the dust with a tackcloth.
Paint the countertop with a second coat of paint and allow the paint to dry.
Sand the second coat of paint lightly with 800-grit wet/dry sandpaper and wipe away the dust with a tackcloth.
Apply a polyurethane finish that acts as a sealant and protectant, using a paintbrush.
