All preparation and painting must conform to AS2311: The Painting of Buildings.
Do not overspread or exceed 12.0 square metres per litre per coat. In hot weather, rinse brush every half hour or use two and keep one standing in water.
Only apply if surface, air and product temperatures are between 10°C and 32°C. Do not apply if temperature is under 10C, or when temperature of surface may fall below 10C during the drying period, otherwise film formation will not be complete and poor properties will result.
All surfaces must be thoroughly dry, clean and free of all loose dirt, grease, mould, surface chalk and loose or flaking paint. New timber surfaces should be sanded smooth and dusted down prior to priming. Fill nail holes, imperfections and cracks with a suitable filler, sand and dust off. Spot prime filled areas.
For hard set plaster surfaces use Dulux sealer binder or Precision High Opacity Stain Blocker as the prepcoat.
Roller, Brush & Spray:
Spray application not recommended for timber surfaces.
Stir contents thoroughly before and during use. Apply direct from the can. May be applied to dampened surfaces. If applied over dry, porous surfaces, dampen surface before applying.
Brush: Wet brushes with water prior to use to avoid clogging. Apply a full even coat direct from the container. Under hot conditions it may be necessary to thin with up to 100ml per litre of clean water.
Roller: Using a medium nap roller apply a full even coat direct from the container and finish by light parallel strokes with a dry roller. Airless/Conventional Spray: Suitable for application by all standard spray equipment. If necessary thin with up to 100ml per litre of water to aid atomisation.
Note: Spray application is not recommended for priming timber surfaces.
Clean brushes and rollers with water after use.
