It can be used as a waterproof coat to be applied on exterior roofs or wall surfaces. The product contains FIBRADO waterproof fibres which effectively prevents accumulated water from entering the floor level. Its 500% elongation also helps to cover up cracks neatly and shield-off water effectively. The effective waterproof mica substantially boosts its weatherproof performance and durability; the Sunreflect technology has a sunlight reflectivity of up to 85%, which helps to reduce the absorption and conduction of heat. The indoor temperature can be reduced by 5.5 degrees Celsius by applying Dulux Waterproof Roof (A959). Theoretically, 1 litre of Dulux Waterproof Roof can cover 2 sqm in 1 coat. Apply in 2 coats to achieve effective coating thickness of 360µm when combined with applying 1 more coat of Dulux Waterproof Coat (A640) for enhanced waterproof properties. Coverage will vary considerably depending on application methods, surface roughness, and porosity. *Dulux Waterproof Roof available in White (55448), Blue (51262), Light Green(53290) and Silver (50383).
