Wooden furniture is a durable, elegant addition to a home. It has defining qualities that require proper treatment if they are to be preserved. Like most wood surfaces, pine wood furniture is likely to lose its finish over time. This can result in a dull or lifeless appearance, which leads to more serious issues after prolonged neglect. Fortunately, refinishing pine wood with a stain and varnish will renew and protect the furniture's condition.
Sand the pine wood with a 100-grit sanding sponge to remove the existing finish and smooth out scratches, dirt and other signs of wear. This prepares the surface for a stain while eliminating imperfections and blemishes.
Dust the pine to remove the loose sawdust and grit left after sanding. Wipe down the wood with a tack cloth to eliminate any remaining traces of dust.
Mix a can of wood stain using the accompanying stirring stick. The stain renews and evens out the pine wood's natural colour. Brush a single coat onto the furniture with a natural-bristle brush; then use a rag to wipe the excess quickly before it dries. Allow the stain to dry overnight.
Saturate the dry pine wood with a sanding sealer using a new brush. Brush the sealer in the direction of the wood grain. Wait for it to become dry to the touch.
Smooth the furniture with a 280-grit sanding sponge to prepare it for sealing. Apply a polyurethane wood varnish to the pine wood with a foam brush or painter's rag; this protective coating preserves the furniture's appearance and provides a durable, vibrant finish. Allow the first coat to dry overnight.
Sand the wood with the 280-grit sanding sponge. Treat the pine with one to two more applications of varnish, but leave the top coat unsanded. The multiple coats will ensure that necessary moisture is sealed into the wood to prevent cracking and drying.
Always choose a well-ventilated area when working with wood stain or varnish to avoid inhaling the fumes.
