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 seam and flashing details on SBS-modified membranes, cracks in concrete or control joints on low-slope roofs, and skylights, chimneys, vent pipes, gravel guards, and downspouts on shingle roofs.
FlintBond 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. FlintBond is not recommended for use on shingles.

Installation
All surfaces must have proper drainage and be clean, dry, and free of surface rust and any other foreign matter. Excessive particulate surfacing materials on modified membranes must be removed (sweeping with a stiff broom is recommended) prior to application. For best results in cold weather, store at room temperature for 24 hours prior to application.
Protective clothing and eyewear should be used during application of this product. Apply by trowel, putty knife, or gloved hand at rate of ⅛” – ¼” thick. For use with repairs, work cement into break or crack, extending 2”–4” beyond the problem area with feathered edges. If the problem area is over ¼” wide or 2” long, embed asphalt-saturated or open-weave fiberglass fabric to reinforce cement, then cover with additional mastic at prescribed thickness. Clean tools with mineral spirits or paint thinner.
