About this product
Henry Air-Bloc 33MR is a UV and fire-resistant, one-component, elastomeric membrane that provides an air barrier on a range of construction surfaces. Liquid-applied with a trowel or spray, Air-Bloc 33MR cures to a tough, monolithic rubber-like membrane that resists air leakage along with UV radiation and weather. Air-Bloc® 33MR is a fluid applied, elastomeric membrane designed to provide a permeable air and water barrier when applied to above-grade wall assemblies. It is single-component, water-based water penetration and long term weathering. Air-Bloc® 33MR combines proven performance with the addition of antimicrobial technology and proprietary fire resistance technology to create an integral mold resistant membrane that achieves compliance with stringent NFPA 285 requirements. Features: Adheres to most construction surfaces, including block, concrete, stone, wood and metal Contains no organic solvents Can be applied to damp concrete
