Expert Verdict — Reviewed by the SuperArbor Pro Desk
This 2-curb kit bundles the M-Bond, M-Thane, stir paddle, and gloves you need, so it is the convenient choice when sealing one or two penetrations on a repair or retrofit. Prime the penetration with M-Bond so it shows 1 in above the installed curb, then fill per the data sheet. For larger jobs with many penetrations, source curbs in bulk boxes and sealants separately.
Follow GAF's published data sheet and local code for penetration sealing, and use fall protection when working on commercial roofs.
