All materials, surface preparations, coating systems and application of coatings are to be in accordance with BSEN ISO 12944 Parts 1-8 inclusive -1998 (except part 5 revised 2007) and BCSA NSSS. Materials are to be stored, prepared and applied strictly in accordance with the manufacturer's product data sheets. All paint shall be by the same manufacturer and shall comply with the EPA (Environmental Protection Act) PG6/23 1998 Regulations. Paint thicknesses quoted are NOMINAL OFT as defined in BSEN ISO 12944-5: 2007 Where applicable, the colour of undercoats shall be compatible with the colour of top finishing coat defined by the Architect or Client. Intumescent coatings to be specified by the Architect to required OFT to achieve the period of fire resistance specified (i.e. 30, 60, 90 or 120 minutes). Intumescent coatings and sealer coats must be supplied by the same manufacturer who is supplying the corrosion protection coatings to ensure compatibility of materials. The manufacturer must supply independent certification of fire test assessments for each fire protection system. lt is recommended that intumescent paint systems are applied in-shop prior to delivery to site and erection of steelwork. Intumescent coatings which are to be externally exposed must be sealed using durable sealer coats.

2.0 Works treatment

2.1 Preparation Abrasive blast clean to SA2% to BSEN ISO 8501-1:2007, or SSPC-SP6, with a surface profile in the range 50-75 microns.

2.2 Primer and intermediate coats to be applied in shop.

3.0 Site treatment

3.1 Inspect all steelwork and ensure that the works system is intact. Any damage from transit or erection should be repaired by abrading exposed substrate to standard BS EN ISO 8501-1:2007, followed by reapplication of the coatings specification to restore the works applied system.

3.2 Clean all surfaces to remove dust and other dry contaminants, ensuring surfaces are free from grease and oil and thoroughly dry, before applying each further coating. Agreement shall be reached between the engineer, the paint applicator and the coatings manufacturer's representative regarding the approved standard of surface cleanliness.

3.3 Bolts to be sheradised- All protruding portions are to be site painted (after cleaning/degreasing) to a specification approved by the Engineer and paint manufacturer to ensure similar anticorrosive properties and compatibility with the surface treatment system used on surrounding areas.

4.0 Finishing coat. Following repairs to priming/ shop coats and cleaning, apply finishing coats as noted- see protective coating system.
