Dulux Weathershield Black is a durable exterior paint that protects against cracking and flaking, with superior colour retention and mould resistance. Its slow-release encapsulated biocide technology helps prevent mould and algae growth. The paint is easy to apply with a roller or brush and dries to the touch in 30 minutes, depending on the temperature. It can be recoated in 2-4 hours, although this time may be longer in cold conditions. Each litre covers approximately 16 square metres.
