GacoFlex AF4700 SeamSeal is a flashing grade, standalone acrylic roof patch designed to be installed in a single application on a variety of substrates. Fabric reinforcement may be added as desired at angle changes, or when flashing irregularly shaped penetrations. Sacrificial tape is recommended when repairing cracks more than ¼” (6.4 mm) in diameter and all cracks that are subject to movement.
Use GacoFlex AF4700 SeamSeal on surface cracks*, control joints*, coping joints*, gutter seams, membrane pinholes, rain collars and fish mouths*, or as pitch pan filler.
*May require the use of sacrificial tape (BUR).
