The best finishes for a new hardwood dining table combine durability, water resistance, and aesthetic appeal. Oil-based polyurethane is a popular choice for its strong protective layer and ability to enhance the wood’s natural grain with a warm, amber tone. Water-based polyurethane offers similar protection with faster drying times and a clearer finish, making it ideal if you want to preserve the wood’s natural color. For a more natural look and feel, hardwax oil or tung oil provides a soft, matte sheen while penetrating deeply to protect from within, though they may require more frequent maintenance. Ultimately, the best finish depends on the desired appearance and how much wear and moisture the table is expected to endure.
