A durable finish is key to protecting your dining table from daily wear. Polyurethane is a popular choice for its water resistance, toughness, and ease of cleaning. Oil-based finishes like tung or linseed oil penetrate the wood, highlighting the grain while providing a natural look, though they require occasional reapplication. Lacquer offers a high-gloss finish and quick drying but may yellow over time. For a matte, natural feel, consider wax, though it’s less protective. Choose a finish based on your lifestyle, maintenance preference, and the desired look of your table.
