You can also opt for a more colorful look with a bold shade of red, blue or green.If your paneling has vertical grooves, you can even use two colors and paint stripes in the grooves for a truly eye-catching look.

You may need to apply additional layers to create a completely even surface, but once the grooves are filled, you can sand, prime and paint the walls.

If you really want to hide the texture of your paneled walls, sponging on the paint is the best method because it provides a highly porous, mottled finish that can conceal the grooves.
