B-TUFF® 921A | NSF-Approved Two-Component Polyurea Waterproofing Membrane

Two-Component, Fast-Curing, NSF-61 Approved Liquid-Applied Polyurea Waterproofing Membrane | Brand: Poly-Tuff Systems International

B-TUFF 921A is a two-component, fast-curing, low-odour, NSF-61 approved, liquid-applied polyurea waterproofing membrane for potable water containment, tank liners, pond liners, and corrosion protection. Confirm suitability, coverage, cure time, and system compatibility against the current TDS, SDS, NSF-61 certification scope, and project specification before use.

Professional system note: NSF-61 approval applies to specific applications and conditions — confirm the certification scope against the current NSF-61 listing and project specification before specifying for potable water contact applications. Confirm the full system specification against the current TDS before use.

Key Characteristics

  • Two-component polyurea — requires accurate mixing and specialized spray equipment; confirm equipment requirements against the current TDS before use.
  • Fast-curing — designed for rapid return to service; confirm cure times against the current TDS as they vary with temperature and humidity.
  • NSF-61 approved — confirm the certification scope and applicable conditions against the current NSF-61 listing before specifying for potable water contact applications.
  • Seamless, liquid-applied membrane — designed to form a continuous barrier; final performance depends on substrate condition, preparation, and application method.
  • Multi-substrate compatibility — designed for use on concrete, metal, steel, asphalt, glass, and wood; confirm substrate preparation requirements against the current TDS before use.

Typical Applications

  • Potable water containment liners — confirm NSF-61 certification scope before specifying
  • Tank and pond liners
  • Corrosion protection on metal and concrete
  • Secondary containment liners

Limitations

  • Requires specialized spray equipment — confirm equipment requirements against the current TDS before use.
  • Confirm NSF-61 certification scope before specifying for potable water contact applications.
  • Confirm substrate preparation requirements against the current TDS before use.
  • Cure time is temperature and humidity dependent — confirm against the current TDS.
