Henry Air-Bloc 16MR is a liquid applied, elastomeric membrane designed to provide a vapor impermeable air and water barrier when applied to above grade wall assemblies. It is single-component, water-based and cures to a tough monolithic rubber-like membrane, which resists air leakage and water penetration. Air-Bloc® 16MR includes an antimicrobial technology to create an integral mold resistant membrane, and offers a broad application temperature range with a proprietary fire resistance technology to achieve compliance with stringent NFPA 285 requirements.

Surface Prep: All surfaces must be sound, dry, clean and free of frost, oil, grease, dirt, excess mortar or other contaminants. New concrete should be cured for a minimum of 16 hours before Air-Bloc® 16M is applied. Concrete surfaces should be free of large voids and spalled areas.
Apply: Air-Bloc® 16MR may be applied by brush, trowel or roller, however, application by conventional air assisted spray equipment in a single or dual-coat application is the preferred method. Apply in continuous, monolithic application without sags, runs or voids, transitioning onto flashing membrane to create a uniform drainage plane and air barrier. Regularly monitor wet mil thickness during application to assure adequate coverage. The preferred method of application is to mark areas off and ensure that the appropriate volume has been sprayed over this area. During spraying, the material should be applied in horizontal strokes ensuring even application of the product, and then applied in vertical strokes, again ensuring even application. In areas where surface is not uniform, i.e., slightly rough with the presence of small indentations and recesses, an added over-spray should be performed. This over-spray should be sufficient to fill the voids, without excessive material application such that slumping or running of the material occurs.
Coverage Rates: Apply per published architectural specifications. Typical application rates include:
• Smooth Surfaces such as exterior gypsum sheathing or formed concrete: 3.7 gal US / 100 ft² (1.5 L/m²) to give a wet film thickness of approximately 60 mils (1.5 mm), and a nominal cured dry film thickness of 36 mils (0.91 mm) , depending on texture and porosity of surface
• Rough Surfaces such as CMU: 5.4 gal US / 100 ft2 (2.2 L/m2 ) to give a wet film thickness of approximately 90 mils (2.3 mm), and a nominal cured dry film thickness of 54 mils (1.4 mm), depending on texture and porosity of surface
