Product Description

Air-Bloc® 17MR is a high-performance, liquid-applied elastomeric membrane engineered to deliver a vapor-permeable air and water barrier for above-grade wall assemblies. This water-based, single-component solution cures into a durable, monolithic rubber-like membrane that effectively prevents air leakage and water penetration.

Equipped with advanced antimicrobial technology, Air-Bloc® 17MR forms an integral mold-resistant barrier. It features a wide application temperature range and proprietary fire-resistance technology, ensuring compliance with stringent NFPA 285 standards.

Features & Benefits

  • Provides strong adhesion to various construction surfaces, including exterior gypsum boards, CMU, concrete, stone, wood, and metal.
  • Offers reliable adhesion to most wall construction surfaces, even when applied to damp concrete.
  • Meets top industry performance standards for superior quality.
  • Achieves compliance with NFPA 285 Exception #2 through testing per ASTM E1354 and ASTM E84 for vertical and lateral flame propagation.
  • Supports low-temperature applications down to 20°F (-6°C) without requiring additives.
  • Delivers a seamless, vapor-permeable elastomeric membrane, ideal for above-grade wall applications.
  • Ensures easy, cost-effective spray application using standard equipment.
