Pro-SystemIt cures to provide completely seamless waterproof protection and has excellent thermal and UV stability, making it suitable for use in all climates.

Pro-System does not brittle, wear away or yellow with age. It uses atmospheric moisture to trigger its cure process and unlike conventional polyurethane systems can cure under water without gassing or foaming. It also becomes resistant to rain damage and may therefore be applied in relatively poor weather without any subsequent loss of performance or durability.
