For a lasting waterproof result, take the following 6 steps:

1. Remove sand, clay and other loose particles from the substrate.
2. Before treatment, clean (degrease) the substrate with Super Degreaser or Super Industrial Cleaner
3. Assess the substrate for present moisture. Allow to dry thoroughly before impregnating.
4. Take precautionary measures to avoid splashing on plastics, paving and glass.
5. In case of any spills, clean immediately with Super Degreaser or Super Industrial Cleaner.
6. Apply the product to the substrate using a flow or spray method at a temperature of at least 8 °C and dry weather. The impregnating agent must be well absorbed with a minimum consumption of 0.5 litres per square metre. If this differs, a second treatment should be carried out at all times.
