How to Finish Tongue and Groove Paneling

What You'll Need
Detergent and soft sponge
Water based wood stain or finish
Paint brushes or paint roller
Acrylic latex polyurethane

Tongue and groove paneling can provide character to any room. For more durable results, the tongue and groove paneling should be finished with a water based stain.

Step 1 – Prepare the Paneling

The paneling should be clean before you start applying the finish. Use mild detergent and a soft sponge to remove any debris. Next, sand the area with 220 grit sandpaper. Be sure that the area is dry before you begin. Also, once you are done, remove all dust before you move on to the next step.

Step 2 – Finish Tongue and Groove Paneling

Apply the water based stain on the paneling using a paint roller or larger paint brushes. You may also use smaller brushes for hard to reach areas or corners. One coat will provide a lighter shade, but you can apply two coats of finish if you prefer a dark finish. Wait for the first coat to be completely dry and then apply the second coat.

Step 3 – Seal the Paneling

You can use acrylic latex polyurethane to seal the paneling. Use a paint roller to apply the sealer.
