Polystick MTS is a fiberglass reinforced homogeneous rubberized asphalt waterproofing underlayment. With a slip-resistant polyolefinic film on the upper surface, Polystick MTS is ideally suited as an underlayment for metal, concrete or clay tile (mechanically fastened to a batten system), and shingle roofing. Polystick MTS has been specially formulated to be high temperature resistant to 265º F, exhibiting exceptional tensile strength and thermal stability. Polystick MTS underlayment is manufactured using patented ADESO® Dual-Compound Self-Adhesive technology, whereby a “true” polymer modified asphalt compound is applied on the top layer and an aggressive self-adhesive compound is applied on the bottom layer. Polystick MTS is packaged in a roll providing 200 sq ft finished roof coverage weighing 70 lbs in a patented Easybox® that facilitates easy handling of rolls.
