PREPARATION

All substrates should be structurally sound. Properly brush clean the surface ensuring that it is rust free, clean and free from loose material. Rough surfaces and protrusions should be evened out and leveled out appropriately. Fully remove any existing coatings, grease or any other surface contaminants.
If there are holes or honeycombing in concrete substrates, fill it with quick patch repair mortar and allow to cure fully before brush applying the waterproofer.
Apply proper flexible silicone sealant to fully seal all joints and corners prior to application of this product. Apply it in thin successive coats with a brush or a roller. Apply a minimum of 2 coats at right angles to each other with a total dry film thickness of 1.5mm. Let the first coat dry (3-4 hours) before you apply the second coat.
