  • 25-mil composite impermeable membrane
  • Comprised of 16 mils of butyl adhesive and 9 mils of HDPP facer
  • Bonds to most surfaces, such as glass mat gypsum sheathing, poured concrete, masonry, steel and wood-based substrates
  • Ideal for drift or control joints, vertical expansion joints, gaps greater than 1” and transitions between dissimilar materials
  • Primerless application allows for faster installation time
  • May be exposed to normal weather conditions for up to 12-months
  • Backed by a Georgia-Pacific limited warranty
  • AAMA 711 Certified

DensDefy™ Liquid Barrier

  • Provides a highly durable, monolithic , elastomeric water-resistive barrier
