How to apply the Overkote system to a concrete surface
Surface preparation
Any dirt, soil or other contaminants must be removed from the roof’s surface before installing the Overkoat system. After the initial clean, the surface should now 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.
Applying the Overkote
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.
