PART 3 — EXECUTION
3.01 EXAMINATION
A. Examine conditions, with installer present, for compliance with requirements for installation, tolerances and other specific
conditions affecting performance of flashing. Remove all deleterious materials from surfaces to be flashed.
3.02 INSTALLATION
A. General: Install flashing to dry surfaces at air and surface temperatures of -4ºC (25ºF) and above in accordance with
manufacturer’s recommendations at locations indicated on Construction Documents. Primer is not requires for most
substrates including plywood provided they are clean and dry. On concrete, masonry, and DensGlass Gold apply Perm-
A-Barrier WB Primer prior to flashing.
B. Flexible Wall Flashing:
1. Precut pieces of flashing to easily handled lengths for each location.
2. Remove silicone-coated release paper and position flashing carefully before placing it against the surface.
3. When properly positioned, place against surface by pressing firmly into place by hand roller. Fully adhere
flashing to substrate to prevent water from migrating under flashing.
4. Overlap adjacent pieces 50 mm (2 in.) and roll all seams with a steel hand roller.
5. Trim bottom edge 13 mm (1⁄2 in.) back from exposed face of the wall. Flashing shall not be permanently exposed
to sunlight.
6. At heads, sills and all flashing terminations turn up ends a minimum of 50 mm (2 in.) and make careful folds to
form an end dam, with the seams sealed.
7. Do not expose flashing membrane to sunlight for more than one hundred and twenty days prior to enclosure.
C. Accessories:
