Touching Up Trim
Instructions for how to prepare stained trim for installation and touch-up. After stained trim or door casing has been installed, see how to properly touch-up the wood for a perfect looking finish. If the stain was applied over a finish like varnish or polyurethane, the stain is sitting on top of the finish, and is not penetrating to the wood. To refinish anything “perfectly” you first have to remove the existing finish, and that can really only be done by chemically stripping the old finish from the wood so that you can get down to bare wood. After the old finish has been removed and the stripper residue has been cleaned off the surface of the wood, the wood would then have to be completely sanded.
