Built up roofing (BUR) primers are primarily solvent-based asphalt primers. Used in flat to low-slope applications with BUR membrane systems, BUR primers enhance adhesion between the membrane system and roofing substrate. They can be used on a range of surfaces including concrete, masonry, metal, gypsum, and new or weathered bituminous surfaces. Asphalt primers are used with both hot- and cold-applied asphalt roofing systems. BUR primers can be applied in a variety of ways, ranging from aerosol to brush roller, depending on the specific product. VOC content for these primers can vary and is generally just reported as less than 350 g/L.
