Expert Verdict — Reviewed by the SuperArbor Pro Desk
Amphibikote earns its place on every service truck because it displaces water and grabs even during a storm, making it the go-to for emergency leak calls. Trowel it generously into the failed detail and schedule a permanent repair later, since it is a repair cement, not a substitute for proper flashing replacement. In cold weather always reach for the Winter grade to keep workability.
Solvent-based asphalt cement: apply with gloves, keep away from ignition sources and provide ventilation during use.
Keep Karnak 155AF Amphibikote on the truck for emergency roof repairs in any weather.
