Products / Mule-Hide A-320 Finish

A-320 Finish is a water-based, 100 percent acrylic elastomeric roof coating that Mule-Hide says can be used as a base or surface coat over smooth and granulated BUR, spray polyurethane foam, most metal roofs, modified bitumen and single-ply membranes, and that it claims has better hail resistance than typical elastomeric roof coatings.
