CertainTeed's FlintBond® Trowel is an all-weather, SBS-modified bitumen flashing and repair mastic specially formulated for use with modified bitumen membranes, base sheets and ply sheets. When used as a flashing cement, it is ideal for SBS-modified membranes seam and flashing details, such as Flintlastic® SA endlaps and granulated details, as well as cracks in concrete or control joints on low-slope roofs as well as skylights, chimneys, vent pipes, gravel guards and down spouts on shingle roofs. FlintBond® Trowel also delivers excellent repair performance on all modified bitumen and built up roofing membranes in wet or dry conditions; it will bond underwater and will remain adhered where movement is expected to occur. FlintBond® will not run, slip, sag, or mud crack. Formulated with superior high temperature resistance, it will remain durable in high heat locations such as heater vent pipes.
