Overcoat is a high-performance flexible STP roofing system that provides instant waterproof protection for virtually any roofing surface, including gutters, joints and seams.

Overcoat is a high-performance, flexible STP roofing system that provides quick, easy, waterproof protection for virtually any roof surface, including gutters, joints, and seams.
The system has been designed for ease of use and requires no fibreglass, no additives and in most cases no primers, once the deck has been cleaned, simply open the can and apply it to the roof with a standard roller.
The system creates a watertight, vapour-permeable membrane that can withstand rainfall immediately. Once cured, Overcoat provides long-term resistance to degradation caused by natural weathering (including extreme temperatures, rain, and snow).
Thermal expansion and contraction in a roof are due to temperature changes, which can cause issues such as cracks, leaks, and other damage if the system cannot accommodate them. Engineered with our eFlex technology, Overcoat provides unparalleled flexibility over standard liquid-applied roofing systems.
Unlike traditional liquid roofing systems, Overcoat doesn’t require any activators or catalysts to work; instead, the system cures naturally with the atmosphere.
