E-Curbs are designed for use on granulated modied bitumen, asphalt and coal tar B.U.R. (built up roong). E-Curbs are
specied for PVC, PIB, and TPO single ply roong membranes. E-Curbs are highly versatile for sealing penetrations around
solar panel mounts, HVAC, electrical, and any type of structural supports. TPO Primer is required for use with TPO.
Place E-Curb sections to form a circle
around the QBase, making sure to lock
them together. Press firmly in place
until excess adhesive extrudes from the
outside edges.
Apply M-1 around circumference of
E-Curbs and where the two sections
intersect. Use the wooden spatula to
spread the sealant to form a smooth
surface.
Fill the E-Curb cavity to the top with
Chem Link's 1-Part solution.
Install QBase to structural member. For
more details refer to the QBase Low
Slope installation instructions.
Seal around the base of mount using
Chem Link's M-1. Coat the QBase, bolts
and post with M-1 to 3" above roof line.
Apply three " beads of M-1 to the flat
base of both E-Curb sections.
NOTE: Be sure to thoroughly read and follow manufacturer instructions for installing Chem Link's E-Curb Penetration System.
