Overview
The Overcoat moisture-tolerant epoxy primer is used on certain roof surfaces where a strong bond is required. The two-part primer once mixed will cover and soak into the existing roof surface to help stabilise and improve the adhesion of the Overcoat roofing system.
Any dirt, soil or other contaminants must be removed from the roof’s surface before applying the primer. After the initial cleaning, the surface should be power washed and rinsed to remove all residual dirt and contaminates after which the surface should be dried.
Fill any cracks with Sharkseal multi-surface sealing adhesive and allow to cure following the product application guide.
