Alternative Panel Layout and Seaming

The following seaming technique is acceptable for only fully adhered roofs.

Lay roof panels out with at least a 2" overlap. Fully adhere roof as instructed earlier. After the roof is adhered, use a straight edge and utility knife to cut through both layers of membrane in the area where the panels are overlapped. (See Figure 15d) Remove the end cuts from both panels. This procedure creates a perfect butt spice in the same manner as a wall paper hanger would.

Using a RUBBERALL® Scrub Pad and Seam Tape Primer Plus prime and area 4" on either side of the butt splice. Center RUBBERALL® 6" Cured Cover With Tape over the butt splice and unroll while removing the backing paper. (See Figure 15e) Roll the cover strip with a steel hand roller, first rolling the length of the seam and then across the seam.
