Installation Options
- Seal and prime penetration: Apply a bead of M-Bond™ at the base of the penetration and then prime the penetration with M-Bond™ 3" so it shows 1" above the M-Curb™ after it is installed.
- Choose the proper curb size: Allow a minimum of 1" clearance from the inside of the curb to the penetration.
- Seal the edges of the curb: Once the edges of the curb are sealed, the newly created pitch pocket is ready to be filled using the M-Thane™ Pourable Sealant.The sealant will be tack-free and water-tight typically in 30 minutes to one hour depending on outside weather conditions.
