How to Restain a Banister

Apply chemical wood stripper to the banister, or use sandpaper to remove the old finish. Chemical wood strippers are easier to use than sandpaper, especially if you have to remove finish from hard-to-reach areas on your banister. Read the directions on the stripping product you choose because the types and directions may vary.

Sand the wood to remove leftover finish and to smooth the wood. If the chemical finish removes most of the paint, a lot of sanding is unnecessary.

Apply grain filler to the wood with a cloth rag or paintbrush. If you are restaining wood other than oak or mahogany, grain filler is likely unnecessary. Allow the filler to dry according to the product's directions.

Remove excess grain filler with a putty knife. Verify the filler is completely dry before continuing with your project.

Apply at least one coat of sand sealer to the wood before you begin staining.

Choose a stain and stain color for your wood. Types of wood stains include oil-based stains, water-based stains, gel stains and one-step stains.

Apply your desired stain to the banister. Depending on the stain's directions, apply more than one coat, and remove as directed.

Wipe any excess stain with a cloth rag, and let the finish dry.
