Application Review

1. SUBSTRATE

• Plywood, OSB or high-density wood fibreboard
• Concrete or brick.
• Insulation boards – except polystyrene insulation.

2. INSULATION

• Insulation joints are butted together with no gaps.
• Correct fastener pattern and quantity used.
• 100% adhesion of the membrane to the substrate.

3. FIELD SEAMS

• Seam Tape Primer should be visible past the leading edge of the field seams (over scrub).
• There are no wrinkles, voids or fish mouths in any portion of the field seams.
• All angle changes in the field seams are flashed over with one ply of 15.24cms wide by 30.48cms long Uncured Flashing with Tape.
• Seam Tape should extend past leading edge of seam. If not, was Lap Caulk used?

4. FLASHING DETAILS

• No bridging occurring in the Uncured Flashing with Tape at any angle changes.
• Two plies of Uncured Flashing with Tape are applied on all outside corners, pipes (when not using a Pipe Boot) and stacks.
• One ply of Uncured Flashing with Tape is applied at all T-Joints field seam angle changes and over inside corner folds.
• Seam Tape Primer Plus is visible past leading edge of flashing (over scrub).

5. TERMINATION BAR

• Apply Water Cut-Off Mastic behind membrane prior to installing the Termination Bar.
• Install a fastener in every hole and maintain a 6.35mm space between bars.
• Termination Bar installed on parapet walls, requires a minimum of 30.48cms above the roof deck.
• Lap Caulk applied over top of Termination Bar.

6. PENETRATIONS

• Uncured Flashing with Tape is applied in two layers a minimum of 20.32cms above the roof deck.
• Peel and Stick Pipe Boots have Water Cut-Off Mastic applied between the pipe and the boot, are terminated with a Pipe Boot Clamp and are caulked with Lap Caulk. 

7. METAL EDGING

• Metal Edge is prepared, cleaned and sanded and of sufficient gauge and adequately fastened to withstand wind uplift.
• Properly stripped in using 15.24cm wide Cured Cover Strip with Tape. Cover Strip with Tape should extend a minimum of 50.8mm beyond any fastener.

8. OVERALL APPEARANCE

• Termination Bars are level.
• Seam widths are uniform and completely rolled in.
• All trash or debris is removed from job site.

Overall appearance is very important.
