How to Refinish Furniture Without Stripping: Benefits
Kevin Southwick specializes in the conservation and restoration of antiques and in custom wood finishes. He also consults in these areas. Kevin's expertise is the result of more than 20 years' experience working with and learning about wood finishes and furniture repair and furniture refinishing.
We'll show you Kevin's tips for cleaning, repairing and restoring finishes without all the messy chemical strippers and tedious sanding. You'll save tons of time. And since you'll preserve the patina and character of the original finish, your furniture will retain the beauty of an antique. One word of caution, though: If you think your piece of furniture is a valuable antique, consult an expert before you do anything.
Assess the Finish with Mineral Spirits
Clean it Up
Kevin recommends liquid Ivory dish soap mixed with water. Mix in the same proportion you would to wash dishes. Dip a sponge into the solution, wring it out, and use it to gently scrub the surface. A paintbrush works great for cleaning carvings and moldings. When you're done scrubbing with the soapy water, rinse the surface with a wrung-out sponge and clear water. Then dry it with a clean towel.
Fix White Rings
If that doesn't work, you can try a product such as Homax White Ring Remover or Liberon Ring Remover. They often work but may change the sheen. If these fixes don't work, consult a pro to see what your other options are for your furniture refinishing project.
Scrape Paint Without Damaging the Finish
The masking tape holds the blade slightly off the surface so you can knock off paint spatters without the blade even touching the wood. Hold the blade perpendicular to the surface. The tape also keeps you from accidentally gouging the wood with the sharp corner of the blade. The curved blade allows you to adjust the depth of the scraper. If you tilt the blade a little, the curved center section will come closer to the surface to allow for removing really thin layers of paint for your refinishing furniture project.
Replace Missing Wood: Apply Epoxy
If you discover missing veneer, chipped wood or a damaged molding, you can fix it easily with epoxy putty. Kevin showed us the process he uses (watch a video of him patching a piece of chipped veneer with Quickwood), and the resulting repair is so realistic that it's hard to spot. When it's hardened, the epoxy is light colored and about the density of wood. You can shape, sand and stain it like wood too, so it blends right in. Quickwood and KwikWood are two brands of this Tootsie Roll?shaped epoxy. You'll find it at home centers and specialty woodworking stores for about $9 a tube.
To use this type of epoxy, you slice off a piece with a razor blade or utility knife and knead it in your gloved hand. When the two parts are completely blended to a consistent color and the epoxy putty starts to get sticky, it's ready to use. You'll have about five or 10 minutes to apply the epoxy to the repair before it starts to harden. That's why you should only slice off as much as you can use quickly.
See photo for how to replace missing veneer. Here are a few things you can do before the putty starts to harden to reduce the amount of sanding and shaping later. First, smooth and shape the epoxy with your finger. Wet it with water first to prevent the epoxy from sticking. Then use the edge of a straightedge razor to scrape the surface almost level with the surrounding veneer. If you're repairing wood with an open grain, like oak, add grain details by making little slices with a razor while the epoxy is soft.
Replace Missing Wood: Finish the Epoxy
After the epoxy hardens completely, which usually takes a few hours, you can sand and stain the repair. Kevin sticks self-adhesive sandpaper to tongue depressors or craft sticks to make precision sanding blocks. You can also use spray adhesive or even plain wood glue to attach the sandpaper. Sand carefully to avoid removing the surrounding finish.
Blend the repair into the surrounding veneer by painting on gel stain to match the color and pattern of the existing grain. You could use stain touch-up markers, but Kevin prefers gel stain because it's thick enough to act like paint, and can be wiped off with a rag dampened in mineral spirits if you goof up or want to start over.
Choose two colors of stain that match the light and dark areas of the wood. Put a dab of both on a scrap of wood and create a range of colors by blending a bit of the two. Now you can use an artist's brush to create the grain. If the sheen of the patch doesn't match the rest of the wood when the stain dries, you can recoat the entire surface with wipe-on finish to even it out.
Restore the Color with Gel Stain
It's amazing what a coat of gel stain can do to restore a tired-looking piece of furniture. The cool part is that you don't need to strip the old finish for this to work. Kevin demonstrated the tip on this round oak table. The finish was worn and faded. He loaded a soft cloth with dark gel stain and worked it into the surface. Then he wiped if off with a clean cloth. It was a surprising transformation. Of course, gel stain won't eliminate dark water stains or cover bad defects, but it will hide fine scratches and color in areas where the finish has worn away.
There are other products, but Kevin prefers gel stain because he finds it easier to control the color and leave a thicker coat if necessary. Also, since it doesn't soak in quite as readily as thinner stains, gel stain is somewhat reversible. Before it dries, you can remove it with mineral spirits if you don't like the results. Gel stains offer some protection, but for a more durable finish or to even out the sheen, let the stain dry overnight and then apply a coat of wipe-on finish as shown below.
Fill Small Cracks
If you find nail holes or tiny cracks after applying the final finish, fill them with colored wax fill sticks, wax repair sticks or fill pencils, found at home centers and paint stores.
The directions tell you to rub the stick over the defect. But Kevin recommends breaking off a chunk and warming it up in your hands. Then shape it to fit the flaw and press it in with a smooth tool. He uses a 3/8-in. dowel with an angle on the end. For cracks, make a thin wafer, slide it into the crack and then work the wax in both directions to fill the crack. Buff with a soft cloth.
Get Rid of Dents
You can often get rid of small dents by wetting them. The moisture swells the crushed wood fibers back to their original shape. (You can't fix cuts or gouges this way, though.)
Moisture must penetrate the wood for this to work. Finishes prevent water from penetrating, so Kevin suggests making a bunch of tiny slits with a razor blade to allow the water to penetrate. Use the corner of the blade, and keep the blade parallel to the grain direction. Next, fill the dent with water and wait until it dries. If the dent is less deep but still visible, you can repeat the process. As with most of the repairs we talk about here, the repaired surface may need a coat of wipe-on finish to look its best.
Renew the Luster with Wipe-On Finish
To apply wipe-on finish, first put some on a clean rag. Apply it in a swirling motion like you would with car wax. Then wipe off excess finish, going in the direction of the grain. Let the finish dry overnight and you'll be ready to proudly display your furniture restoration project after you've learned how to refinish a table.
