Tape Application
Second – Apply Top Piece
1. Apply top piece of weather barrier self-adhering
tape so one end extends 1" beyond a side piece of
tape (FIGURES 4 & 4A). Apply top piece across
the head jamb and over the opposite side piece
of tape. Both ends of top piece should overlap
side pieces by 1". Use a rubber roller to get good
contact with the wall surface.
2. Apply a sealant bead along the top piece of
weather barrier self-adhering tape. Place bead
where flap of WRB will seat when folded down
(FIGURE 5).
3. Untape and fold down the top flap of weather
resistant barrier over the top piece of the weather
barrier tape (FIGURE 6). Use a rubber roller, on
top of flap, to smooth and spread sealant applied
earlier.
4. The diagonal seams in the weather resistant
barrier must be sealed.
Cut and apply self-adhering weather barrier tape
as shown in (FIGURE 7) to seal the seams. Cut
tape big enough to overlap seam by at least 1" on
all sides.
