Backstop NT 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 three versions:

• Backstop NT-Texture is applied using a trowel, roller, or texture spray equipment
• Backstop NT-Smooth is applied by roller or texture spray equipment
• Backstop NT-Spray is applied by airless spray equipment

Backstop-NT Texture, Smooth, and Spray are designed for use with Dryvit Systems as well as other building cladding systems. When used with the Dryvit AquaFlash® System or Dryvit Flashing Tape™, Backstop NT provides exceptional air barrier and water-resistive membrane for most substrates.
