On the basis of design documentation for the device should be corrosion resistant coatings to develop the project of works (CPD) in accordance with the requirements of SNIP 01/03/01, of which should include flow sheets device to separate anti-corrosion coatings. In the process maps on the device coatings should provide the following basic requirements: – the preparation of materials – "the preparation of the surface structure under the protective covering – "Application of primer or primer-impregnation -" a protective coating in one or more layers – "keeping the coating on the air until it hardened, drying or heat treatment; – "Okislovke surface. Materials used for corrosion resistant coatings device must comply with the requirements of existing TNLA. Their quality must be confirmed by quality certificate of the manufacturer and in accordance with applicable law, – the certificate of conformity of the National System of conformity or technical evidence. Transportation, warehousing and storage of materials, as well as structures and equipment coated with a protective coating on the construction site should be in accordance with the requirements of TNLA for this product (product). Quality Control Devices anticorrosive coverings should be in accordance with the requirements of existing TNLA. The ambient air temperature, shielding materials and surfaces to be protected must not be below 10 C – for paint coatings, prepared on the basis of natural resins, mastic and coatings shpatlevochnyh of silicate materials okleechnoy protective coatings on the basis of bitumen roll materials, poliizobutilenovyh plates, duplicate polyethylene gummirovochnyh coatings facing and lining coatings arranged on kislotoupor-GOVERNMENTAL silicate plaster, on the mastic bituminol; for acid-concrete and concrete-silikatopolimer; surface impregnation, 15 C – to paint the reinforced and unreinforced coatings and liquid covering a bearing of the materials prepared by synthetic resins, mastic coatings and sealants Nairit prepared on the basis of synthetic rubbers; coating of sheet polymeric materials lining and lining coatings, carried out on plaster arzamit, furaktor, polyester, epoxy resins for polymer concrete, cement and polystyrene, cement and cement-perchlorovinyl casein plasters.

25 C – for latex coatings (such as "sex"). Work to protect building structures against corrosion should be done after all prior to construction works, the production process where the protective coating can be damaged. When the negative air temperature corrosion work should be carried out in heated rooms or shelters, if the project documentation is not provided the possibility of the device of the coating at low air temperatures. At negative temperatures may only restoration of damaged anticorrosion coatings (except for the use of sacrificial metal plasters). Relative humidity in the production of anti-corrosion work should be not higher than 70%. The metal surface prepared for the production of anti-corrosion work, should not have burrs, sharp edges, weld spatter, rolls, burn-through, flux residues, slag, oxides formed during welding, defects produced during the rolling and casting in the form of non-metallic makrovklyucheny, sinks, cracks, delamination, uneven, and the fat-pounds of pollution, rust and old paint. The most thoroughly be cleaned surface in the zone of welds up to 3 cm of flux residues, slag and alkali oxides formed during welding
