321 K-NRG Seal VP is a liquid-applied, flexible membrane designed to provide a vapor-permeable air and water barrier for above-grade wall assemblies. This single-component, water-based acrylic coating cures to a robust, rubber-like membrane that expands and contracts, resisting air leakage.

  • Uniform, breathable, elastic membrane for above-grade walls
  • Easy application via spray, roller, or brush
  • Built-in mold resistance
  • High water vapor permeability for 'breathability'
  • Superior adhesion to common surfaces, even damp concrete
  • Meets NFPA 285 Fire Test standards, surpassing ASTM E2178 and E2357
