Can anyone suggest a product or material to use as a terminating bar, near ground level, for my XT650 Polyguard Membrane?  So far I have used a 1/2 inch bead of mastic at the seams, and I am planning on parging the  remaining exposed ICF from the seem to the termination of the ICF.  If I parge, can that be the "terminating bar"???  I have about 50 feet by 6 inches of horizontal ICF showing and then a partially exposed wall (24 feet) with the ground sloping rougly 45 degrees down the wall.  Bottom line, do I need an additional product in addition to the mastic and parging?

I appreciate any help you can give me.
