Description;

Product Description & uses: Roofmaster is a flexible coating designed for application to new and previously painted (sound) roofs, walls and masonry. Roofmaster is particularly suited for application to asphalt and bituminous emulsion coated surfaces in addition to concrete, brick, asbestos, cement etc., weathered GCI and aluminium etc.

Characteristics: Based on flexible 100% pure Acrylic emulsion formulation incorporating high-quality lightfast pigments.

Advantages: Excellent adhesion and weathering properties. The flexible film minimizes crazing when applied to bitumen-based substrates. Water-based, quick-drying and easy to apply. Economical and easy to maintain. Allows the substrate to breathe and can therefore, be applied to surfaces which still contain up to 15% moisture.

Finish: Matt.

Colour Range: Red Oxide, Beetle Green, Cornflower and Brick Terracotta. Other shades available upon request.

Application: By brush or roller. Can be applied by spray equipment if necessary. For best results the application of 2 coats of Roofmaster is recommended.

Drying times: Re-coatable after 3-4 hours in dry conditions.

Thinning: The thinning of Roofmasteris not recommended except when the product is to be applied to textured surfaces when a little clean water can be added to ease brushing. Stir well before use.

Spreading capacity: The spreading capacity of Crown Roofmaster will vary greatly depending on the porosity and profile of the surface. Spreading capacity, when applied to a smooth, non-porous surface, will be approximately 10-12 m2/l.

Pack sizes: 1 litre, 4 litres and 20 litres

Surface preparation: Prior to applying Roofmaster to asphalt and bitumen emulsion surfaces ensure that the substrate is clean and dust free and in sound structural condition. When coating flat roof surfaces, ensure that all surface rainwater is thoroughly removed and the surface allowed drying out. The substrate may be damp but there must be no actively percolating water.

New galvanized iron and aluminium surfaces require thorough degreasing with Crown White Spirit before coating. Ensure that the surfaces are completely clean and dry. Galvanized iron and aluminium roof sheets that have not be allowed to weather for a minimum of six months should be etched with Crown Passivating Wash/ Mordant solution before painting commences.
