Polycoat PC 550 SC – Single-Component Elastomeric Waterproofing Membrane

PC 550 SC is a single-component, water-catalyzed polyurethane polyurea liquid-applied elastomeric waterproofing membrane. Designed for seamless, high-performance waterproofing across a wide range of substrates, it delivers fast cure times and reliable long-term protection — with no mixing required.

Fast-Curing, Seamless Waterproofing Protection

PC 550 SC cures quickly upon exposure to atmospheric moisture, forming a continuous, seamless membrane that eliminates the weak points associated with seams and overlaps. Its non-gassing formula ensures a smooth, bubble-free finish even at elevated application thicknesses.

Versatile Substrate Compatibility

From concrete and masonry to metal, plywood, and ship decks, PC 550 SC bonds to a broad range of surfaces. Its flexibility makes it suitable for both structural and architectural waterproofing applications where movement and thermal cycling are factors.

Engineered for Demanding Environments

Built for high-traffic and high-exposure environments, PC 550 SC performs in applications including parking decks, helicopter pads, pedestrian membranes, and under-tile installations — anywhere a durable, watertight barrier is required.
