Parapet Inside Corners Base of corner: Make a “V”-shaped cut in the Flintlastic APP modified bitumen membrane to permit it to conform to the inside corner fold (both sides of the “V” will neatly overlap when folded into the corner). Use a trowel to press the heated membrane flaps into place. Top of corner: Cut a notch part way to permit the top of the membrane to conform to the inside corner and fold over the top of the parapet. Cap the resulting gap with a strip of Flintlastic APP modified bitumen.
