5. Gel Stain Over Worn Wood

When a coffee table or side table has good wood underneath but years of scratches and fading on top, gel stain can bring the color back without a full strip-and-sand marathon.
Unlike liquid stain, gel stain sits on the surface rather than soaking in, which means you can apply it over an existing finish as long as you scuff it first with a fine sanding pad. Wipe away dust, then apply the gel stain with a foam brush in the direction of the grain. Let it sit for a few minutes, then wipe off the excess with a lint-free cloth to control how dark the result gets. Work in small sections so the stain doesn’t dry before you wipe it.
Once it’s fully cured, seal with a wipe-on polyurethane in a satin finish. Two or three thin coats give protection without a plastic look.
Time: an afternoon plus curing time. Difficulty: beginner to intermediate. This technique works best on solid wood and wood veneer. Skip it on heavily peeling pieces, since the gel stain won’t fix flaking finish.
