How to apply the Overcoat roofing system to waterproof lead
Surface preparation
Any dirt, soil or other contaminants must be removed from the roof's surface before installing the Overcoat system. After the initial cleaning, the surface should be power washed and rinsed to remove all residual dirt and contaminants after which the surface should be dried.
Applying the Overcoat
Once the surface preparation has been completed you apply the Overcoat system with a standard roller or brush at a rate of approximately 1.2 kg per square metre. The Overcoat layer will become instantly watertight and can immediately withstand rainfall. After 24 hours the surface can take foot traffic and a full cure of the system will take around 7 days.
