Gaco GacoFlex AF4700 SeamSeal 5 Gallon

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. Not intended for low-slope applications (< 2:12) or over surfaces prone to ponding water. GacoFlex AF4700 can be directly applied to aluminum, galvanized metal, APP, and SBS mod bit and asphalt roofing materials. A primer is recommended for most other substrates.

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).
