- minimize joints. Fold flashing at corners and at ends of
- pans instead of cutting.
-
- B. Joints: Provide not less than 4 inches (100 mm) of
- overlap at flashing joints.
-
-
- PART 3 EXECUTION
-
- 3.1 EXAMINATION
-
- A. Verify that surfaces to receive flashing are thoroughly
- dry, free from loose materials, and reasonably smooth,
- with no sharp edges or projections.
-
- B. Verify that locations to receive flashing are sloped so
- water that enters will drain to building exterior.
-
- 3.2 PREPARATION
-
- A. Self-Adhering Flashing: Prime all surfaces to receive
- self-adhering flashing, and allow to dry for not less
- than 20 minutes prior to flashing application.
-
- 3.3 INSTALLATION
- NOTE ** Edit the paragraphs below to conform to project
- requirements. Most paragraphs pertain to copper-
- based flashing. If self-adhering or PVC flashings
- are only types required, retain paragraphs that
- deal with installation of those types.
-
- A. General: Comply with recommendations of SMACNA ASMM.
- 1. Lap joints minimum of 4 inches (100 mm) and seal
- watertight with mastic.
- 2. Carry flashing vertically as detailed, but not less
- than 6 inches (150 mm) above horizontal plane.
- 3. Extend head and sill flashings not less than 6 inches
- (150 mm) beyond edges of openings and turn up to form
- watertight pan; seal with mastic.
-
- B. Masonry Flashing: Comply with requirements of Section
- 04810.
- NOTE ** Delete paragraph above or below.
-
- C. Masonry Flashing: Lay horizontal flashing in slurry of
- fresh mortar and top with fresh full bed of mortar to
- receive masonry units. At vertical surfaces, spot
- flashing with mastic to hold in place until masonry has
- set.
- 1. Carry flashing through wall and leave exposed for
- inspection.
- 2. After inspection, cut flashing flush with surface of
- masonry.
-
- D. Flashing in Frame Construction: Comply with requirements
- of Section 06100.
- NOTE ** Delete paragraph above or below.
-
- E. Flashing in Frame Construction: Install over solid
- backing, both vertically and horizontally. Secure in
- place with mastic; avoid puncturing installed flashing
- with nails or other fasteners.
-
- F. PVC Flashing: Lay flashing in full trowel coat of
- mastic, lapping joints not less than 6 inches (150 mm).
- Roll surface of flashing with rubber hand roller to
- remove all air.
-
- 3.4 ADJUSTING
