The Polydeck® 165SC decking system is a waterproof liquid applied polyurethane system. The system utilizes an epoxy primer, one coat of a fast setting water catalyzed polyurethane basecoat with a rubber aggregate that can be applied at any thickness, and one or two coats of an aliphatic polyurethane topcoat. The Polydeck® 165SC decking system is designed to expand and contract with normal structural movements. The Polydeck® 165SC decking system can be applied to protect surfaces against spalling, freeze/thaw damage, and chemicals commonly encountered on these surfaces. Polydeck® 165SC is resistant to weathering. It will not soften in heat nor embrittle in cold. The system is designed for use in a wide range of applications. Installed and maintained properly, the Polydeck® 165SC decking system will ensure years of service.
