This British Standard gives recommendations for good practice in preparation, initial painting and maintenance painting of buildings (e.g. dwellings, offices, light industrial buildings, schools, hospitals, hotels and public buildings generally) internally and externally, in which decoration is a significant and often the major factor. This British Standard takes into account the need to protect many building materials against weathering or other forms of attack normally encountered. Detailed information is given on wood, metal, masonry and other typical substrates found in buildings. The paints and coating materials referred to in this British Standard are principally those in common use, with limited reference to specialist coating materials and factory-applied coatings. Some materials have been excluded because of their obsolescence, limited or specialized usage or, in the case of newly developed products, lack of experience of their performance in service. This British Standard does not cover: the protection of structural steel elements (see BSENISO12944, and BS5493 for iron structures), including hot spray application; decorative processes and other work usually carried out by specialists, such as asbestos encapsulation, the maintenance of lead surfaces, resin flooring, polymer renders or waterproofing of flat roofs; the particular requirements of listed or historic buildings which are protected by law; limewash and distemper coating materials; preservative treatments for structural timber; reactive coating materials for passive fire protection and systems consisting of these materials (see BS8202‑1, BSEN16623 and BS476); and general safety hazards of access for painting (see BS8210). The recommendations made in this British Standard are intended to facilitate achievement of standards of finish which, when inspected as described in Clause 10, will be of a generally acceptable commercial standard for the intended types of buildings, providing that the work of other trades has been completed to a satisfactory standard. Where especially high standards of finish are necessary, more elaborate processes and systems than those described in this British Standard might be necessary.
