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
