Precautions and limitations

All preparation and painting must conform to AS2311: The Painting of Buildings.
Do not overspread or exceed 14.0 square metres per litre per coat. In hot weather, rinse brush every half hour or use two and keep one standing in water. Do not apply if temperature is under 10°C, or when temperature of surface may fall below 10°C during the drying period, otherwise film formation will not be complete and a fall-off in properties will result.

Hadrian Contractor Plaster Sealer is not recommended for set plaster. Dulux Sealer Binder is recommended as a barrier coat for the set plaster applications.
