IB Smooth Backed Membrane

Starting at the lowest point of the roof position IBPVC membrane begins with full sheets, and aligns the role of the membrane to provide a minimum three-inch side left. Apply IB waterborne adhesive in accordance with the manufacturer's instructions using a roller or squeegee at the specified rate, and unroll the membrane into the adhesive taking care to avoid seam contamination. Note, as an alternative option, you may unroll both membranes. Position the sheets to provide a minimum three-inch sideline, and fold the membrane sheets back lengthwise, so the underside of each sheet is exposed. Apply the adhesive to the substrate and slide the membrane into place. Immediately roll or broom membrane from inside to outside to work out any entrapped air and make the membrane make full contact with the adhesive to accomplish a proper bond. Upon completing the installation, ensure all seams and laps are inspected and probed. If deficiencies are found, the area must be re-welded or repaired.
