Apply with a pressure sprayer. Procoat Roof Clean Concentrate is best applied in overcast conditions to avoid rapid evaporation. Do not apply if rain is expected within 4-5 hours. Wet approximately 10m2 at a time ensuring the surface is well saturated. For best results, as the surface starts to dry out rewet again lightly. Do not rinse off. Procoat Roof Clean will slowly treat the surface, reactivating when it rains.
If treating roofs used for the collection of drinking water, ensure the water supply is disconnected until a minimum of 5 rainfalls or 30mm of rain has fallen.

Procoat Roof Clean is a slow release formula that continues to treat the surface over many months. Once treated, a badly contaminated surface may take months to become clean. For best results, ensure that the mixing and application instructions are followed, and if necessary increase the strength for faster results.
