Installation: - Start at the lowest part of the roof deck and install valley conditions first.
- Cut the CLAD-GARD SA to a length that can easily be managed and lay the membrane flat in place with the print side up.
- Along the side of the sheet, overlap the seams a minimum of 3” (76 mm).
- At the ends of the sheet, overlap a minimum of 6” (152 mm).
- Peel half of the release liner off the roll and apply with even pressure from the center of the sheet to the outer edges. Remove the remaining release liner from the other half of the roll and apply pressure in the same manner.
- In steep slope applications, backnailing may be recommended. When backnailing, be sure that all nails are covered by the next overlapping sheet.
CLAD-GARD MA (Mechanically Attached) - Polypropylene two-sided coated fabric
- Patent-pending slip resistant surface
- Apply directly to Firestone HailGard composite, OSB and plywood substrates
- Eligible for up to a 20-year Red Shield warranty
Installation: - Starting at the lowest part of the roof deck lay the membrane flat in place with the print side up.
- Cut the CLAD-GARD MA to have 4” (101 mm) horizontal laps and 6” (152 mm) vertical laps on a minimum 5:12 roof slope. Overlaps should run with the flow of water in a shingling fashion.
- Using a minimum 1” (25 mm) diameter cap nails, secure the underlayment by driving the nails squarely into the approved substrate.
- Spacing should be 6” (152 mm) on center on both head and end laps, and 12” (304 mm) on center in the field area in the center of the roll.
