Lacquer furniture polish is a fast-drying finish applied to wooden furniture to protect the wood from damage. Lacquer finishes are solid yet flexible, so the finish smoothly wraps the wood while preventing scratches and chips.
Lacquer comes from the resin of the varnish tree and is mixed with a synthetic resin called nitrocellulose. This mixture lets the lacquer dry extremely quickly, keeping dust from settling in the finish before drying. However, it also makes applying lacquer somewhat difficult; the finish must be applied evenly and quickly. Lacquer can be applied by brushing or by using an aerosol lacquer spray. While the aerosol cans are more expensive, About.com contends that they are the best choice for small projects.
