Polycoat PC-50 – Accelerator & Thickener for PC-220 Urethane Membrane

Fast Cure, Thixotropic Additive – Apply Two Coats in One Day

PC-50 is a single-component, proprietary liquid accelerator and thickener designed specifically for use with Polycoat PC-220 and other Polycoat base membranes. When added to PC-220, PC-50 enhances the moisture-curing characteristics of the urethane — accelerating cure time and increasing viscosity to create a thixotropic compound that stays where you put it.

The faster cure time allows applicators to apply two coats in a single day, significantly reducing labour cost and job site time on deck coating projects.

Key Features

• Accelerates cure time — speeds up the moisture-curing process of PC-220 for faster return to service
• Creates a thixotropic compound — increases viscosity so the coating holds on vertical surfaces and doesn’t sag or run
• Two coats in one day — faster cure means base coat and broadcast coat can be completed the same day
• Single component — simple liquid additive; mix directly into PC-220 before application
• Saves labor cost — reduce job site visits and crew time by completing multi-coat systems faster

Typical Uses

• Plywood joint caulking — creates a caulking-grade compound for sealing deck joints before membrane application
• Crack filling — thickened compound stays in cracks without slumping
• Concrete expansion joints & flashings — ideal for detail work requiring a heavier-bodied material
• Vertical surfaces — thixotropic properties prevent sagging on walls, curbs, and vertical transitions
• Fast-turnaround jobs — when quick access or same-day recoat is required

Performance & ROI

• Two coats in one day — cut a two-day job to one, reducing crew costs and site disruption
• Eliminates sag on vertical surfaces — thixotropic compound holds position without additional passes
• Seals joints & cracks in one step — use as a caulking compound before membrane application to eliminate weak points
• Works with PC-220 — engineered specifically for Polycoat base membrane systems

Compatible with: Polycoat PC-220 Waterproofing Urethane Membrane and other Polycoat base membranes.
