    • New/aged coated or uncoated metal roofs
    • Renocation of concrete roofs
    • For protection of metal roof - especially at joints to prevent ingress of rain and water become contaminants
    • Provides good bonding on most coated and uncoated metal roof and improves the total solar reflectance of system

    What are the benefits of MasterSeal 378?

    • High solid content
    • Elastomeric with good tensile strength
    • Good bonding to new or old coated metal
    • Water based
