Roof Walkway Protects Foam Roofs


West Development Group (WDG), a leader in sustainable roofing products and practices, introduces the Z-Guard Pedestrian Traffic System for use on sprayed-in-place polyurethane foam roofs. Z-Guard is a one-component, moisture curing, silicone/quartz liquid composite slurry designed for use around all equipment requiring servicing, as well as areas of heavy foot traffic. The Z-Guard reinforced, silicone walkway is a dispersion of silicone rubber, organic hardeners, and quartz aggregates. It is a one-part, ready-to-use material that can easily be applied to a dry, frost-free surface, and cures at normal temperature in 12 to 18 hours by reacting with moisture in the air. It is tack-free in 1 to 2 hours. Z-Guard has a Shore “A” hardness of 80 psi and is trowel applied. Minimum coverage rate is 66 sq. ft. per 5-gallon bucket. WDG Z-Guard is available in 10 oz. cartridges, and 2 gallon or 5 gallon buckets. These products have a shelf life of 12 months from the date of manufacture.
