FOLDED OUTSIDE EDGES: The simplest and most reliable way to seal the intersection of two outside edges is simply to bend the sheet over the edges and gather the excess rubber to form a triangular projection. Since bonding adhesive is applied to the underside of the rubber when the sheet is installed, the triangular projection becomes internally adhered. No external adhesive is required: just fold the projection to one side, secure it with a Termination Bar, and caulk the top.
STEP 1: Bend and adhere
the rubber over both edges.
STEP 2: Gather the excess to
form a triangular projection.
STEP 3: Fold the triangle to one side.
STEP 4: Clamp the folded
rubber with a Termination Bar.
STEP 5: Caulk the open top of the fold.
TAPED OUTSIDE EDGES: As an alternative, the intersection of two outside edges can be cut and flashed with tape. Since bonding adhesive is applied to the underside of the rubber when the sheet is installed, once the excess rubber is trimmed all the rubber at the outside edge is fully adhered. A disc of Uncured Laminate Tape can be stretched and formed around all three surfaces at the corner: using a hot-air gun to soften the tape will make this process easier.
STEP 1: Cut the overhanging
rubber at a 45° angle to both edges.
STEP 1: Fold and adhere the rubber
over both edges, pressing into the tape.
STEP 2: Cut off the excess rubber.
STEP 3: Cut a disc of Uncured Laminate
Tape and position it over the corner.
STEP 4: Form the tape so that it
stretches onto all surfaces without folding.
STEP 5: Press the tape firmly
so that it bonds to all surfaces
