Coats: 1 coat is normally sufficient. If used on exterior objects, two or three coats is recommended. Drying Time: 2- 3 hours depending on temperature and humidity. Re-coating Time: 2- 3 hours depending on temperature and humidity. Preparation: Surface must be clean and free from all traces of wax, grease and metal polish. Lightly tarnished surfaces should be cleaned with a good quality metal polish, which must then be removed with warm soapy water. If the surface is not smooth, a nail brush should be used to ensure there is no polish left in the crevices. The article should then be dried with a cloth.

It sets by a process called "aqua-polymerization", absorbing oxygen to set; placing in a humid environment allows it to absorb more oxygen from the evaporation of the water. Asian lacquerware, which may be called "true lacquer", are objects coated with the treated, dyed and dried sap of Toxicodendron vernicifluum or related trees, applied in several coats to a base that is usually wood. This dries to a very hard and smooth surface layer which is durable, waterproof, and attractive in feel and look. Asian lacquer is sometimes painted with pictures, inlaid with shell and other materials, or carved, as well as dusted with gold and given other further decorative treatments.If possible objects such as letterboxes should be removed from the door so that at least one coat of lacquer can be applied to the edges of the reverse side.

The English lacquer is from the archaic French word lacre "a kind of sealing wax", from Portuguese lacre, itself an unexplained variant of Medieval Latin lacca "resinous substance," from Arabic lakk ( لك), from Persian lāk ( لاک‎), from Hindi lākh ( लाख); Prakrit lakkha, 𑀮𑀓𑁆𑀔), [3] [4] [5] [6] itself from the Sanskrit word lākshā ( लाक्षा) for lac bug, representing the number one hundred thousand (100,000), used as wood finish in ancient India and neighbouring areas. [7] Laksha is a traditional form of lacquerware from Sri Lanka which is made from shellac derived from Lac. Sheen measurement [ edit ] Lacquers are usually solvent based, which means brushes and spraying equipment need cleaning with white spirit / thinners. Lacquers using acrylic resin, a synthetic polymer, were developed in the 1950s. Acrylic resin is colourless, transparent thermoplastic, obtained by the polymerization of derivatives of acrylic acid. Acrylic is also used in enamel paints, which have the advantage of not needing to be buffed to obtain a shine. Enamels, however, are slow drying. The advantage of acrylic lacquer is its exceptionally fast drying time. The use of lacquers in automobile finishes was discontinued when tougher, more durable, weather- and chemical-resistant two-component polyurethane coatings were developed. The system usually consists of a primer, colour coat and clear topcoat, commonly known as clear coat finishes. Trade of lacquer objects travelled through various routes to the Middle East. Known applications of lacquer in China included coffins, music instruments, furniture, and various household items. [16] Lacquer mixed with powdered cinnabar is used to produce the traditional red lacquerware from China.
