Proteus Pro-System® provides a completely seamless waterproof protection. Unlike conventional polyurethane systems, it uses atmospheric moisture to trigger its cure process meaning it 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. Once cured, it provides a completely seamless waterproof protection with excellent thermal and UV stability, making it suitable for use in all climates.
