Titanium PSU30 Peel & Stick Roof Underlayment

The Titanium PSU30 Peel and Stick Roofing Underlayment is the only modified rubberized asphalt PEEL & STICK underlayment with a tough, rugged surface and a self-sealing lap system. Titanium's PSU30 self-adhering membrane peel and stick underlayment can be used under many types of roofing materials including metal, tile, shakes, slate, and both asphalt and synthetic shingles. It is equipped with an advanced synthetic polymer surface, making it slip-resistant. This Titanium underlayment has a slip-resistant coating that allows for easier steep slope walkability when applied while the roof is being added. Titanium's PSU30 self-adhering synthetic roofing underlayment is designed for 2:12 or greater sloped roof applications subject to the effects of ice damming and wind-driven rain. The PSU 30 underlayment can be used as metal underlayment, rubberized asphalt underlayment, and tile roof underlayment.

To install this peel-and-seal roofing underlayment, first, make sure your surface is free of debris and dry. It may be applied directly to a plywood, OSB, concrete, or masonry roof surface and should be fully covered as soon as possible or within 180 days. Priming is not required for attaching to wood surfaces when the temperature is above 40°F. Concrete and masonry decks should be primed with a solvent or a water-based primer that meets ASTM D41 for asphalt-based self-adhesive membranes. To apply this synthetic underlayment, peel back 1-2 feet of release liner, align the membrane then hand press or walk on, and follow with a 40 lb or heavier pressure roller to smooth and secure the membrane.
