Some lacquer finishes can be sprayed to provide wood protection.
Most wooden furniture and floors are finished with spray or brush products that add an attractive, protective layer to the raw wood. One of the most popular of these products is lacquer varnish. It offers several distinct advantages over similar products such as wax, oil, polyurethane and shellac, including fast drying and good wear resistance. The varnish finish is also relatively long-lived, stain resistant, and will not oxidize or become brittle. In addition, a lacquer finish does not change color or tone as it dries, allowing the carpenter to better assess the finish from the moment of application.
Vegetable resin, which is used to make some lacquer finishes.
Lacquer finishes are derived from organic plant resins mixed with a solvent drying agent. They feature some of the fastest drying times of all protective finishes, which has a number of advantages. The first is the obvious improvement in recovery; Lacquer-finished pieces generally dry in less than half the time of those treated with other products. The second advantage is an improved surface quality due to reduced dust adhesion. The space taken up by drying is also reduced, which further enhances the aforementioned production cycle improvements.
The lacquer finish dries quickly and its color stays the same wet or dry.
Another notable advantage of the lacquer finish is its longevity and overall wear resistance. Parts finished with lacquer products wear well, resisting discoloration from heat, spills of water, oils, dilute acids and alcohol. The lacquer finish also resists cracking due to heat modulation or wood shrinkage. Lacquer also does not oxidize and becomes brittle or brittle over time, as is the case with many oil-based products. These factors give lacquer finishes an exceptionally good lifespan, allowing them to remain attractive and usable longer than many other treatments.
The lacquer finish facilitates the maintenance of furniture parts.
From a carpenter’s point of view, one of the attractive features of a lacquer finish is the stability of color and tone throughout the drying cycle. Many other products change tone and shade as they dry, making it difficult to assess the final result when applying the topcoat. Varnish finishes, both clear and dyed, maintain the same color and tone throughout all stages of application and curing, which gives a good indication of the final result from the first coat. A cured varnish finish can also be left with a matte, satin, or polished surface to a mirror-like shine, depending on the desired end result. Once polished, the varnish is hard enough to retain its shine for the lifetime of the finish, subject to normal use.
