How can I ensure the longevity and durability of my wooden furniture by applying a protective finish?

To ensure the longevity and durability of your wooden furniture, apply a protective finish such as varnish, lacquer, or polyurethane. These finishes create a barrier that protects the wood from moisture, scratches, and other damage. Apply multiple coats for added protection and follow the manufacturer's instructions for best results. Regularly clean and maintain your furniture to preserve its finish and extend its lifespan.
