237-2% Neo-Asphalt

Karnak #237-2% AF Neo-Asphalt is an -free cold applied, rubberized asphalt cement, designed especially as an adhesive for paving blocks and pressed asphalt bricks, eliminating the need for a hot kettle.











USES


Karnak #160.1 Amphibicaulk is a cold process, heavy bodied, caulk-grade roof cement ideal for sealing leaks in and around asphalt built-up roofs, joints chimney cracks, skylights, vents, down-spouts and gutters. The dried film retains its flexibility and ductility, so the caulking will resist extreme variations in temperature and weather. Karnak #160.1 Amphibicaulk may also be used to improve wind resistance on low slop shingle roofs.
