Black Wind & Water Seal™ is a 55 mil, self-adhesive mineral surface roofing underlayment, which is adhered directly to the roof deck. The specially formulated rubberized asphalt adhesive seals around nails and fasteners to form a waterproof barrier.
Black Wind & Water Seal™ is backed with a protective release liner which removes easily during application. The release liner is slit in the middle for easy valley applications. The sand surface contains a high-strength, non-woven fiberglass mat which is coated with a rubberized asphalt compound.
