Lacquer and lacquering

Abstract

Scope of Study: This report deals with the history and development of lacquer, its characteristics, application methods, and the equipment necessary for its proper use. Desirable characteristics of a lacquer finish, as well as some of the common faults, are discussed. General information, rather than technical data, concerning the modern finishing product known as "lacquer" is presented. The equipment described does not include all types that are available, but typical equipment used in industry that is suitable for use in the school shop is discussed. A complete glossary of common finishing terms is not included, but some of the terms used in the lacquer industry are defined. Common faults of lacquer finishes, such as blushing, orange peel, bridging, discoloration, sags and runs, and how to overcome them are discussed.

Findings and Conclusions: Lacquer is a very old finishing material, having been in use for more than 2,000 years. Present day lacquers are quite different, in composition and characteristics, from the early lacquers used by craftsmen in the Orient. Within the last thirty years vast improvements have been made in nitrocellulose lacquers, and they have largely replaced other finishes in industry. The automotive industry led the way in making lacquer popular, but in recent years the furniture industry has become a great consumer of the product. In order to maintain pace with the finishing industry, industrial arts departments need to install spray painting equipment in the school shops. Students should be instructed with the materials and equipment used in industry.
