Stone Edge Surfaces Pro Bond Ultra Cover Board is for commercial low slope or flat roof roofing systems. Pro Bond Cover Board is primerless, has 100% adhesion to the LWIC, Styrofoam or other roofing materials. Pro Bond Ultra Cover Board does not require any adhesives, and does not require mortar to fill the spaces between cover boards, voids around obstacles or the roof edges.

Pro Bond Ultra Cover Board has been tested, certified and approved by multiple LWIC (foamcrete) manufacturers for adhesion to their materials, and by multiple hot mop and membrane manufacturers for their adhesion to Pro Bond Ultra, and can withstand the full heat of hot mop material application.
Pro Bond Ultra Cover Board Material has also been “independently” pump tested and certified by Strong Manufacturing Co Inc. for ease of use, pumpability and pumping distance of multi-story structures.
Pro Bond Ultra is ASTM E84 Fire and Smoke tested and certified with a Class A rating, has been tested for wind uplift and hail protection.
