A flexible waterproofing tape used when flexibility is called for in a flashing system. A cross-laminated polyethylene crepe film with a rubberized asphalt layer. A release paper protects the asphalt and is removed as the tape is installed. The white crepe face 70 mil. film allows it to be stretched and curved around arched windows, doorways, and other irregular openings. Easy-to-apply and self-seals around nails, screws, and staples. Apply directly to OSB or wood sheathing, under almost any exterior surface, including brick, stucco, vinyl, or metal siding. The result is a secure barrier against rain, moisture, and wind - and a quieter, more energy-efficient structure in the long run.Can be applied at temperatures as low as 50 deg. and be left exposed for up to 90 days. 5 year limited warranty. 6" x 50'.
