Polyurethane or lacquer is commonly used to protect wooden cabinets due to its durability and resistance to scratches, heat, and moisture. These finishes create a hard protective layer that seals the wood, helping to preserve its natural beauty while also enhancing its appearance.

Polyurethane, available in both oil-based and water-based formulations, provides a tough finish that is ideal for surfaces that experience a lot of wear and tear, making it suitable for kitchen and bathroom cabinets. Lacquer, on the other hand, dries quickly and has a high-gloss finish, which is often desired for its aesthetic appeal.

Other finishes exist, but they may not provide the same level of protection or durability. For instance, while oil-based paint can also offer some durability, it generally does not provide the same level of moisture barrier as polyurethane or lacquer. Watercolor paint lacks the robustness needed for cabinetry and is more suited for artistic applications. Shellac, although it can offer a nice finish, is less durable and more susceptible to damage from heat and water compared to polyurethane and lacquer.
