3. Activity description Regulations 3.1 This note applies to LAPPC installations for the re-spraying of road vehicles. The activities for regulation are listed in Table 3.1.

A consolidated version is not available on www.legislation.gov.uk. For England and Wales, an unofficial consolidated version is available but read the first page of that document in order to understand its status and content. 3.2 This note refers to the refinishing of road vehicles and associated degreasing activities performing: The coating of road vehicles as defined in Directive 2007/46/EC, or part of them, carried out as part of vehicle repair, conservation or decoration outside of manufacturing installations, 3.3 In the context of this note, “process” or “activity” comprises the whole process from receipt of raw materials via production of intermediates to dispatch of finished products, including the treating, handling and storage of all materials and wastes relating to the process. 3.4 Most, but not all, vehicle refinishing is uniform as there is little variation in the objects coated, coating products and application methods used. The following paragraphs describe the majority of processes. PG6/34(11) 8
Application Methods 3.5 Most coatings are applied in vehicle spray booths with hand-held spray. Spraying in the open workshop should not occur. A small amount of coating or remover is applied by brush, roller or with a knife. The different techniques available are listed below. There is some further description of the spraying techniques in Definitions. compliant compressed-air spraying high-volume low-pressure (HVLP) spraying airless spraying air-assisted airless spraying spray processes with electrostatic assistance brush/roller application knifing Surface cleaning and preparation 3.6 Substrates must be cleaned before painting. This is generally done manually, using brushes and cloths, with organic solvents or with aqueous cleaners. Use of hand pump spray equipment reduces the amount of cleaning liquid required. Abrasive blasting as well as phosphate spraying can be used to improve paint adhesion and to assist underbody protection. 3.7 Any surface unevenness is remedied before painting. Major depressions up to 1cm are filled with a stopper. Minor depressions are smoothed with fine stopper or alternatively with a spray stopper. The stopper is ground to the desired profile after curing. 3.8 Sanding/grinding can be wet or dry. Larger areas are sanded mechanically, whilst smaller areas and edges are sanded by hand. Dry sanders are equipped with a suction device to remove the sanding dust from the workspace. 3.9 For subsequent tasks, the stopper surfaces are carefully cleaned. If necessary, silicone removers are employed, as silicone residues can disrupt subsequent paint layers. 3.10 Use of paint strippers based on methylene chloride is now much restricted, as damaged panels are more usually replaced, rather than being beaten out, stripped, and repainted. The repair of vintage cars is one area of continued use. Very good ventilation is required to maintain workplace exposure below the OEL, and waste must be segregated to avoid the risk of contaminating drains with residues of methylene chloride.
