Seaming Membrane Panels with Seam Tape
After adhering the membrane sheets so that the width of the seam is the width of the seam tape used, remove excess chalk from a chalk line by snapping the line into the air and then chalk a line 13mm from the leading seam edge.
Fold the top sheet back to expose the seam area. (Hint: A small piece of seam tape that is tacky on both sides is useful to tack the membrane back.) If the EPDM membrane is contaminated with dirt, dust or debris, clean the seam area with Membrane Cleaner on a cotton cloth before applying Seam Tape Primer Plus. Using the Scrub Pad, apply the Seam Tape Primer Plus to the area with back and forth strokes and moderate pressure until the seam surface attains a smooth black appearance. Apply the Seam Tape Primer Plus past the seam edge to the chalk line. Allow the primer to dry.

Seam Tape comes in rolls of 7.62cm x 7.62mtrs and 7.62cms x 30.48mtrs.
Unroll the Seam Tape along the length of the seam, tape side down, aligning the Seam Tape paper with the chalk line. Using moderate pressure, draw the Scrub Pad or roller along the Seam Tape release paper. This will set the Seam Tape into place and keep air from being trapped under the tape. Fold the top membrane onto the Seam Tape release paper.
