How to Seal a Wood Bathroom Vanity Top with Sink

A wood bathroom vanity top with sink can add a touch of rustic charm to any bathroom. However, it is important to seal the wood properly to protect it from damage caused by moisture, spills, and everyday use. Proper sealing will help to ensure that your vanity top will last for many years to come.

Materials Required:

Sandpaper (120-grit and 220-grit)
Tack cloth
Wood filler
Putty knife
Wood sealer
Sponge brush or paintbrush
Lint-free cloths

Step 1: Prepare the Vanity Top

Begin by sanding the vanity top with 120-grit sandpaper to remove any existing finish or imperfections. Wipe away the sanding dust with a tack cloth. Fill any holes or gaps in the wood with wood filler using a putty knife. Allow the wood filler to dry completely, then sand it smooth with 220-grit sandpaper.

Step 2: Apply the First Coat of Sealer

Apply a thin, even coat of wood sealer to the vanity top using a sponge brush or paintbrush. Work in the direction of the wood grain. Allow the first coat to dry for the recommended time specified on the product label.

Step 3: Sand and Apply Second Coat

Lightly sand the vanity top with 220-grit sandpaper to remove any raised grain or imperfections. Wipe away the sanding dust with a tack cloth. Apply a second coat of wood sealer in the same manner as the first coat. Allow the second coat to dry completely.

Step 4: Cut Around Sink Opening

If your vanity top has a sink opening, use a utility knife to carefully cut around the edges of the opening. Be sure to cut only through the sealer, not the wood. Remove the excess sealer around the opening.

Step 5: Seal the Sink Rim

Apply a thin bead of silicone caulk around the rim of the sink where it meets the vanity top. Smooth the caulk with your finger or a caulk tool. Allow the caulk to dry completely.

Step 6: Apply Third Coat of Sealer

Apply a third coat of wood sealer to the vanity top, including the area around the sink opening. Allow the third coat to dry completely.

Step 7: Clean and Protect

Wipe down the vanity top with a damp lint-free cloth to remove any remaining sanding dust or debris. Apply a layer of furniture wax or polish to the vanity top for additional protection and shine. Buff the wax or polish with a clean lint-free cloth.
