Not a nano-coating or standard impregnating agent.
The fabric needs to be clean and dry before treatment. Spray Ultramar Sail & Spinnaker Coating generously and evenly, from left to right and from top to bottom. A thin layer is more than sufficient. Wait until it dries. Subsequently, treat the other side of the sail cloth and then let it dry well.
Usage depends on the type of fabric:
50 ml is good for 1,25 m²
Do not inhale the spray mist.
Use only in a well-ventilated area.
