Wet-Sanding

Step 1

For most of us, finishing means applying varnish, polyurethane, or paint with a brush. The dream of a glass-smooth tabletop is always spoiled by brush marks and bits of dust and other debris. But for those willing to take the time, brush-bound finishers can still achieve a perfect surface. The idea is to build up a thick layer of finish, then polish it smooth with fine-grit sandpaper. Here's how.

1. Sand the surface to 320-grit. Thoroughly remove sanding dust from the pores of the wood using compressed air of a shop vacuum and tack cloth.

Paste wood filler, top center, makes a smooth foundation for the finish. Wet-sand with a simple solution of liquid detergent and water, left, using a rubber sanding block, bottom center. Polish with an automotive wax, bottom right.
