CAN BE APPLIED UP TO 125 MICRONS DFT IN A SINGLE COAT VIA SPRAY APPLICATION. GOOD CHEMICAL & ABRASION RESISTANCE. TINTABLE - AVAILABLE IN OVER 5000 COLOURS. ACCELERATOR AVAILABLE FOR USE IN COOLER CONDITIONS.. USES WEATHERMAX HBR has been locally developed for high build roller or brush application. It is a high build recoatable polyurethane coating designed to be used over a wide range of suitably primed substrates such as mild steel, galvanised steel, concrete and aluminium.
2 WEATHERMAX HBR is a high performance coating that exhibits excellent gloss and colour retention during extended service periods in severe industrial and marine environments and in extreme UV exposure SPECIFICATIONS AS/NZS Tested in accordance with Appendix C & D for use as a concrete anti-carbonation coating system when used with Durebild STE. RESISTANCE GUIDE. WEATHERABILITY Excellent gloss and colour retention on SOLVENTS Resists splash and spillage of most exterior exposure hydrocarbon solvents, refined petroleum products and most common alcohols HEAT RESISTANCE Up to 120 C dry heat WATER Excellent resistance to fresh and salt water but not suitable for immersion SALTS Unaffected by splash and spillage of neutral ALKALIS Good resistance to splash and spillage and alkaline salt solutions of most common alkalis ACIDS Excellent resistance to splash and spillage of ABRASION Good when fully cured most acids TYPICAL PROPERTIES AND APPLICATION DATA (STANDARD HARDENER).

9 Remove grease, oil and other PREPARATION contaminants in accordance with Degrease with Gamlen CA No. 1 (a free-rinsing, alkaline detergent). according to the manufacturer's written instructions and all safety warnings. Abrasive blast clean to a minimum of Class Galvanised steel: Round off all rough welds, sharp edges, and zinc dags and remove weld spatter. Remove grease, oil and other contaminants in accordance with Whip blast, taking care not to damage the galvanising layer. Remove all dust by vacuum cleaning. Concrete: Concrete must be at least 28 days old before coating . Remove all laitance, form release, curing compounds, oil, grease and other surface contaminants.
10 Diamond grind, track or light shot-blast concrete floors to provide a profile. Remove all dust by vacuum cleaning. Fill any large cracks or voids using Luxepoxy Filler. Non-ferrous substrates: Round off all sharp edges. Remove grease, oil and other contaminants in accordance with Whip blast with fine non-metallic media such as plastic, glass or garnet to provide a key. Remove all dust with compressed air. Alternatively, degrease and abrade the surface with a non-metallic abrasive pad, such as Scotch-Brite scourer wetted with Gamlen CA No. 1 (a free-rinsing, alkaline detergent) and water. Rinse thoroughly with fresh water.
