2.2 COATING SYSTEMS Refer to SELECTIONS for type. Where additional information on selected materials and finishing products is necessary include it here. Otherwise include all relevant information under SELECTIONS.

3. EXECUTION

Conditions

3.1 CONDITIONS FOR PAINTING Coat steelwork in conditions approved for the application of the specified coatings. Carry out off-site preparation and coating application under cover, in a suitable environment, with adequate lighting and with the air and steel temperature between 5°C and 25°C. Ensure prepared and painted surfaces are clean and dry. Do not carry out preparation or painting when the ambient relative humidity exceeds 85% (80% for CAP products), or when the steel surface temperature is within 3°C of the dew point.

3.2 COATING APPLICATION Apply coatings strictly in accordance with the manufacturer's stated requirements. Ensure that the manufacturer's latest product data sheets are available for reference during preparation and painting.

3.3 COMPATIBILITY Ensure that materials are as required by their manufacturers for the particular surface and conditions of exposure, and that materials used within each painting system are compatible with each other and are from the same manufacturer, or manufacturers with a formal relationship for use of each others products.

3.4 SEQUENCE OF OPERATIONS Complete surface preparation before commencing painting. Apply paint in the specified sequence using the specified paint. Allow full drying time between coats to the manufacturer's stated requirements. Do not expose primers, undercoats and intermediate coats beyond a few days before applying the next coat.

3.5 DRYING TIME Before handling or applying the next coat of paint, give each coat the required drying time required by the manufacturer. Ensure that surfaces being painted are clean, dry and that ambient conditions are such that condensation does not occur before the paint reaches surface- dry condition.

Preparation - metal substrates

3.6 UNPAINTED SURFACES Do not paint: - Faying face of high strength friction grip (HSFG) bolted joints - Areas for site welding keeping 75mm clear all round - Surfaces for embedding in concrete.

3.7 WIRE BRUSHING AND POWER TOOL CLEANING Remove oil and grease by the use of solvents. Scrape and power wire brush to a minimum class St 2 finish to AS 1627, part 2. Clean to bright metal, but avoid producing a polished surface. Check that no burrs or sharp arrises remain which may prevent full coating thickness being attained. Alternative method includes abrasive blasting to AS 1627, Part 4, Class 1.

3.8 ABRASIVE BLASTING Remove oil and grease by the use of solvents. Abrasive blast clean to a class 2.5 finish to AS 1627, Part 4. Clean to bright metal, but avoid producing a polished surface. Select grit type and equipment such that the cleaned surface profile between peaks and valleys does not exceed one third of the dry film thickness. Check that no burrs or sharp arrises remain which may prevent the full coating thickness being attained.

3.9 PREPARING GALVANIZED AND ALUMINIUM SURFACES Remove grease, oil and other solvent-soluble contaminants by wiping and/or brushing with mineral turpentine or white spirit, according to AS 1627.1. Finally wipe with clean solvent. Allow to dry and proceed with the next operation immediately. Lightly abrade surface if required to provide adequate key for coating, taking care to only minimally reduce the galvanizing thickness.

3.10 PREPARING ZINC PRIMED SURFACES Do not apply Phoenix Intumescent directly to any Zinc Rich or Inorganic Zinc Silicate primer coat, use of an approved epoxy tie coat (e.g. Duremax GPE-ZP). Zinc primers must be free from zinc salts, remove if present. Remove grease, oil and other solvent-soluble contaminants by wiping with mineral turpentine or white spirit. Finally wipe with clean solvent. Allow to dry and proceed with the next operation immediately. Some chalking and yellowing will occur to Duremax GPE ZP with exposure to weather if not top coated within 4 weeks of application. This will not detract from the resistance properties of the coating, if wash down and abrading of Duremax GPE ZP is undertaken prior to the application of Phoenix Intumescent 170, 370 or 700. Inorganic zinc silicate primer coatings will require sealing with an approved sealer prior to application of an intumescent material.

3.11 SHOP PRIMING Dust off and apply a coat of primer. Generally use primers to give a single coat thickness of 50-75 microns. Use primers that suit the standard of preparation. High performance primers will require abrasive blasted surfaces rather than wire brushing. Ensure suitable, compatible undercoats and top coats are specified elsewhere. Also check the manufacturer's literature.

3.12 PATCH PRIMING Clean areas of damaged priming and areas left clear for site jointing to a standard comparable with the shop cleaning specified. Wash off chemical deposits from welding fumes. Apply priming coats to same standard as shop primers, ensuring thorough coating of bolts, nuts and connection areas. Re-prime if the primer fails.

3.13 SITE REPAIR METALLIC/MIO FINISHES Spray application (conventional or HVLP) on site is recommended for repair and touch up of MIO or Metallic finishes.

3.14 SITE COATING High pressure fresh water wash down all surfaces. Lightly sand down primer/intermediate coats, which have been shop applied, prior to site application of next coat. Ensure all surfaces are clean and dry prior to any coating application. Do not carry out preparation or painting when the relative humidity exceeds 85% (80% for CAP products), or when the steel temperature is within 3°C of the dew point.

3.15 AESTHETIC FINISH When a high quality aesthetic finish is required, a thorough sand of the Intumescent coating is recommended prior to applying the finish coat.

Preparation - timber substrates

3.16 PREPARATION - BARE UNCOATED TIMBER Lightly sand to provide a smooth surface suitable for a clear coating. Perform an adhesion test and sample for opacity to ensure the substrate is compatible with CAP.

Fill holes, cracks and surface imperfections with an appropriate filler. Sand to a smooth, clean, dry finish, free of any contamination to ensure proper adhesion. Remove any contaminates by wiping with methylated spirits, or clean dust off surface with a damp cloth. Check moisture content of timber is below 15%.

3.17 PREPARATION - PREVIOUSLY VARNISHED TIMBER Ensure existing coating is hard and suitable for sanding. Lightly sand to provide a consistent key for CAP using 180 grit sand paper. Ensure all gloss and clear areas have achieved a matt, roughened up appearance.

Fill holes, cracks and surface imperfections with an appropriate filler. Sand to a smooth, clean, dry finish; free of any contamination, to ensure proper adhesion. Remove any contaminates by wiping with methylated spirits, or clean dust off surface with a damp cloth. Check moisture content of timber is below 15%.

3.18 PREPARATION - PREVIOUSLY BLONDED OR STAINED TIMBER Prepare timber in accordance with Zone Architectural Products Ltd specific requirements. 3.19 PREPARATION - FIBROUS PLASTER / PLASTERBOARD / LATH AND PLASTER SUBSTRATES Thoroughly wash and rinse surfaces with warm soapy water and sponge to remove all dirt, dust, grease, wax, oil, and any other contaminants. Change the wash and rinse solutions frequently. Clean with a soft cloth and allow to dry. Fill holes, cracks and surface imperfections with an appropriate filler. Scrape off all loose and flaking paint and sand smooth remaining edges of substrate.

Application - general

3.20 DRY FILM THICKNESS Provide the intumescent dry film thicknesses specified. Information required:

3.21 WEATHER PROTECTION OF INTUMESCENT COATED STEEL SECTIONS Phoenix intumescent coatings (Phoenix 700-60, 370-120, and 170-120) can be site or shop applied. Ensure intumescent coated sections are protected against ponding or pooling water on site. Phoenix solvent based intumescent coating (170-120) can be exposed to weathering conditions on site for a limited time before requiring full topcoat protection. Phoenix water based intumescent coatings (700-60 and 370-120) must be top coated with approved topcoat system if the steelwork is likely to remain exposed to weathering on site.

3.22 EACH COAT Each coat of paint and the completed paint system to have the following qualities and properties: - Uniform finish, colour, texture, sheen and hiding power - The proper number of coats applied - Free of defects such as pinholing, alligatoring, blistering, staining, overspray, peeling, runs, sags and wrinkling.

3.23 SITE APPLICATION Site application of intermediate and/or topcoats may require additional coats to achieve the specified DFT.

Completion

3.24 LEAVE Leave the whole of this work uniform in gloss, texture and colour, free from painting defects, clean and unmarked, and to the standard required by following procedures.
