B-3 is a self-adhering mineral surface underlayment which is adhered directly to the roof deck to form a long-lasting protective barrier under shingles, tile and other types of roofing.
The specially formulated rubberized asphalt seals around nails and other fasteners to form a lasting, waterproof bond. It is constructed from a strong layer of mesh bonded to rubberized asphalt and coated with black mineral granules.
Designed to be used as protection against leading edge ice dams, melting snow and wind-driven rain, IB-3 may also be used on valleys, eaves, ridges and anywhere an extra layer of protection is required. IB-3 is NOT intended for use under metal roofing without approval from the metal roofing manfacturer. Primer is recommended before application.
