What Is a Lacquer-Based Paint?

Nitrocellulose

• This lacquer is formed by immersing wood and cotton pulp – broken down into cellulose through exposure to acids – in a fast-drying solvent. Nitrocellulose is easy to use and dries very quickly. It is best sprayed onto the surface, but may also be applied with a brush. It polishes well after drying and forms good protection over the wood. The coats blend together well, making future repairs seamless and worry free. Unfortunately, it does tend to yellow and shrink with age, which causes aesthetic problems, and it is highly flammable during use.

Acrylic

• To avoid the yellowing problem, acrylic lacquers are made of acrylic resins and cellulose acetate butylene in solvent. This mixture dries perfectly clear and stays clear throughout its life. It is often a chosen clear coat over lacquer base and other paints. It protects the undercoat from marks and scratches and helps it wear better. Acrylic lacquers are somewhat more expensive than nitrocellulose.

Catalyzed

• These lacquers were created for use in high-abuse areas like kitchens and bathrooms; they are able to withstand heavy traffic and adverse conditions like high humidity without showing wear. Rather than using a solvent, these dry chemically and cure to the surface. They are composed of nitrocellulose and urea resins with the addition of an acid that acts as a catalyst. Post-catalyzed lacquers require mixing before use, and all directions must be followed closely.

Pros and Cons

• The advantages of lacquer-based paints include their fast drying time and ease of application. They do not run, bleed or chip. They protect the wood they are used on by completely sealing it. The disadvantages of these paints is that they are high in greenhouse emissions or VOCs, and their improper use is a known pollutant. Care must be taken to clean sprayers and brushes immediately after use or they will be ruined, as the dried lacquer cannot be removed without causing damage to the equipment.
