Outside corners of any angle can be flashed with Uncured Laminate Tape. This is a 6” wide self-adhesive lamination of uncured EPDM rubber and Butyl seam tape that has no “memory” so it can be permanently stretched around a three-dimensional corner. Since Uncured Laminate Tape becomes thinner as it stretches, an outside corner is always flashed with two pieces of tape, one applied to either wall, so the thickness is doubled where they overlap at the corner.
STEP 1: Cut the EPDM roof sheet at a
45° angle and adhere it up both walls.
STEP 2: Clean the rubber carefully,
both on the roof and the two walls.
STEP 3: Tape one wall with 2” of the tacky
side folded out, extending 2” past the corner.
STEP 4: Unfold the tape and
bond it to the roof sheet.
STEP 5: Wrap the tape around the corner,
stretching it to contact the roof and wall.
STEP 6: Clean the surface
of the newly applied tape.
STEP 7: Tape the other wall,
extending 2” past the corner.
STEP 8: Unfold the tape and wrap it
around the corner over the first tape.
STEP 9: After cleaning, shingle additional
tapes to the desired height, overlapping 2”.
STEP 10: Roll all surfaces
firmly with a steel roof roller.
STEP 11: Caulk the perimeter of
the tape as well as the overlap seam.
