If you have some wood furniture that requires a new finish or you want to extend the life of a dreary-looking piece of wooden furniture and you’re sure it needs more than just cleaning, your next step should be to refinish it.
Stripping and refinishing wood furniture in a clean, well-ventilated place is the best way to minimize the accumulation of dust and fumes. Wearing protective gloves, brush on the furniture stripper and let the piece sit. After the chemical stripper has softened the old finish, scrape the finish with a wooden scraper.
Sand the wood until it is smooth. Some veneers are so thin that, by sanding the surface, you actually wind up sanding through the veneer at the same time. If you are fortunate enough to have a piece with a 1/4-inch veneer, the piece will respond perfectly to this refinishing process. Use an orbital sander with 80 or 100 grit sandpaper to remove most of the finish. Once that’s done, switch to a higher grit to get rid of any remaining stain or paint. For areas that are awkward or impossible to reach with the sander, you will need to use sanding block, or a small piece of sandpaper.
Repair Before Refinishing Wood Furniture
If your piece of furniture needs repairs as well as refinishing, make the repairs after stripping and before refinishing. Check to be sure the joints are tight because stripping can melt glue and thus cause joints to loosen. If that happens, be sure to tighten the joints before proceeding with the refinishing. As you are regluing the areas, you may find that the veneer has swelled from water infiltration. If this is the case, carefully slice both sides of the damaged veneer until the piece lays flat.
There are several options when it comes to staining wood. You can choose between water-based, oil-based, gel stains, and one-step stain/finishes. When you apply the stain, you should wipe off the excess immediately and then continue to apply thin coats, wiping the excess off each time. If you need to stain both sides of a piece of wood and want to save time by doing the second side before the first dries, just tip the piece gently against a wall or another support so that only the edge of the wood is touching.
Varnish Furniture after Staining
After staining a piece of furniture, brush on a coat of varnish. Let the varnish dry, then sand the piece with fine-grit sandpaper. Repeat the process until you have three or four coats. Use thin coats of varnish, and sand progressively more with each coat to bring down “high” areas and fill in “low” areas. The sanding will even out the surface, making it smoother.
Get a Smooth Finish
For a smooth surface on your refinished piece, sand the last coat of varnish with wet 600-grit wet-or-dry sandpaper. Then make a muddy mixture of 3/4 cup of pumice, a squeeze of lampblack and enough paraffin oil to make the mix soupy. Brush the stuff on with an old toothbrush or, for wider areas like tabletops, a small floor brush. Use long, continuous strokes. Immediately clean up behind your strokes with rags. The lampblack will hide any white grit in the crevices. Switch to a clean rag for a final pass over the furniture to make sure you wipe off any residue. Then buff with the high-quality polish or wax of your choice.
