The AkroFlex Water Managed Plus (WM+) System is a class PB system utilizing a water-resistive/air barrier coating and a means of draining incidental moisture to the exterior. AkroFlex WM+ consists of the AkroGuard/AkroFill water-resistive/air barrier coating system applied over approved, properly prepared substrates. Foam board is attached to the sheathing using vertical ribbons of adhesive. Then base coat with mesh fully embedded is applied over the foam. Lastly, primer (optional) and AkroFlex 100% acrylic finish are applied. Like a standard PB system, AkroFlex WM+’s finish and base coats are designed to keep moisture on the exterior surface, but WM+ adds an additional layer of moisture protection with a water-resistive coating.
