How do you paint a bathroom arborite counter top?

To paint an Arborite countertop in a bathroom, start by thoroughly cleaning the surface to remove any dirt or grease. Next, lightly sand the countertop to create a texture for better paint adhesion, then wipe away the dust. Apply a primer designed for laminate surfaces, followed by a high-quality, durable paint suitable for countertops, using a foam roller for an even finish. Finally, seal the painted surface with a clear topcoat to protect it from moisture and wear.
