Backstop NTX is a flexible, polymer based, noncementitious, air/water resistive barrier, which resists water penetration, eliminates air infiltration, and is vapor permeable. It is classified as a Class III vapor retarder over vertical, above grade walls. Backstop NT is available in two versions:
•Backstop NTX-Texture is applied using a trowel, roller, or texture spray equipment.
•Backstop NTX-Smooth is applied by roller or texture spray equipment.
Backstop-NTX Texture and Smooth are designed for use with Dryvit Systems as well as other building cladding systems. When used with the Dryvit AquaFlash® System, Backstop NTX provides exceptional air barrier and water-resistive membrane for most substrates.
