When I lay down the pre-cut tape on the lace and hit it with the dryer and "pinch", it "melts" i.e. bonds the tape onto the lace flat and eliminates any chance of separation of the tape from the base thereafter. Once tape is pinched/melted onto the base, backing of tape is removed and I brush (craft brush) the two separate layers of UH. For me, this creates a rock solid extended bond onto my scalp.
