Professional cabinet builders typically use a variety of finishes to coat their cabinets, depending on the desired appearance and level of protection. Some common finish options include:
Lacquer: Lacquer is a popular choice due to its quick-drying properties, durability, and ability to create a smooth, glossy surface. It provides a hard and durable finish, making it suitable for high-use areas like kitchen cabinets.
Conversion Varnish: Conversion varnish is a two-component finish that offers excellent durability and chemical resistance. It provides a beautiful, clear finish that enhances the natural wood grain.
Polyurethane: Polyurethane is a durable finish that comes in both oil-based and water-based formulations. It offers good protection against scratches and moisture and is relatively easy to apply.
Oil Finishes: Tung oil, linseed oil, and Danish oil are examples of oil finishes that penetrate the wood to provide a natural, low-sheen appearance. While they offer less protection compared to other finishes, they can bring out the wood's natural beauty.
Water-Based Finishes: Water-based finishes are environmentally friendly and have lower levels of volatile organic compounds (VOCs). They dry quickly, are non-yellowing, and provide good protection.
Shellac: Shellac is a traditional finish made from natural resins. It produces a beautiful, warm, amber tone, but it is not as durable as other modern finishes.
Catalyzed Finishes: These are advanced finishes that contain a catalyst, providing superior hardness and chemical resistance. They are often used in commercial and high-end applications.
The choice of finish will depend on the specific project requirements, the type of wood used, and the desired appearance. Professional cabinet builders will consider factors such as durability, aesthetics, ease of application, and environmental considerations when selecting the appropriate finish for their cabinets.
