Acid Catalyst
The weak acid catalyst component used to cure an AC lacquer.
Air Displacement
The volume of air (measured in cubic feet per minute or CFM) which is pushed through a pump by the piston.
Bar

Blooming
Term used to describe the hazy film or whitening produced when the weak acid in either an AC or PC reacts with the Stearate used as a sanding aid in certain sanding sealers.

BS 476: Part 6 (1989)

Expressed as a rating between Class O and Class 4, Class O being the highest rating.
BS 476: Part 7 (1997)
The British Standard reference associated with tests which determine a products ability to resist the spread of flames over its surface when subject to a specific heat source. Expressed as a rating between Class 1 and Class 4, Class 1 being the highest rating.

CFM
Measurement unit of air output from a compressor – Cubic Feet per Minute.
Clean and Touch-up
Revival of the lacquered surface without re-polishing.

A spray system that supplies air to the gun constantly. Typically used with turbine spray units.
Cracking
Fracturing of the coating, primarily as a result of excessive veneer or substrate movement.
Crazing
A network of fine cracks as opposed to lateral fractures with or against the grain, typically caused by poor application practices such as application of hard lacquers over soft lacquers, the use of the wrong thinner or too much thinner and too short drying times prior to re-application.
Denib
The action of slightly 'flatting' or sanding between coats of lacquer to aid intercoat adhesion and to remove any slight imperfections in the film.
