Can You Paint an Existing Countertop?
- Find a granite pattern or another design for the countertop painting that you like. Look at both the colors and the patterns of the granite or other design. Because it is a natural stone, the patterns vary, with some very busy and others having subtle patterns. Purchase paint for each of the colors in the granite or other design. You also need white vinegar, KILZ primer for non-porous surfaces and water-based polyurethane with a glossy finish.
- The surface heeds to be clean so the primer and paint adhere well. Wipe the countertops with white vinegar to get them completely clean. Paint on your primer once the vinegar dries. You can use either oil- or water-based primer as long as it is made specifically for non-porous surfaces. Allow the primer to dry fully before applying the paint.
- Practice your countertop painting technique on a piece of cardboard before attempting it on your countertop. Start by brushing on the primary base color over the entire countertop. Let it dry completely before moving on to the next step. Use a paintbrush, old towel or a stencil brush to blot on the main accent color of the granite pattern. The base color should show through. Use the granite sample as a guide when applying your accent color. Blend the paint as you apply it if you want a blended look. You can also leave more defined blotches of paint. Splatter on any other accent colors in the granite. A toothbrush or paintbrush dipped in the paint works well for splattering. Let the paint dry fully. In total, apply three coats of your water-based polyurethane, allowing each layer to dry fully. This protects the paint job from everyday use.
