This sealant forms a seamless barrier that keeps rain out while remaining pliable through temperature swings. The neutral, crystal-clear finish helps protect the roof appearance without drawing attention to the repair.

Beyond leaks, the formula supports ongoing maintenance around roof fixtures and penetrations, helping you extend the life of roofing components and reduce airborne moisture intrusion.

Application tips and conditions

• Apply in a wide range of temperatures from 0 to 120 degrees Fahrenheit
• Surface prep: clean, damp or wet surfaces are compatible; the sealant adheres to damp substrates
