Eocflex s
ECOFLEX-S is designed to be an air and moisture vapor barrier membrane for a variety of above-grade surfaces including concrete, block, gypsum and metal for cavity walls. It is applied with a unique, self-contained sprayer to produce an instantaneous, monolithic membrane with excellent adhesion. ECOFLEX-S is a low-viscosity, water-based, anionic bituminous/asphalt emulsion modified with a blend of synthetic polymerized rubbers and special additives, which is highly reactive and exhibits exceptional bonding, elongation, vapor retarding and build characteristics. It performs as a non-permeable air barrier while being non-hazardous, non-toxic and fire-resistant (VOC compliant). Its noteworthy tensile strength, in addition to its weather-resistant qualities, makes it a superior air barrier. ECOFLEX-S has an instant build, allowing for applications in inclement weather and eliminates the risk of shrinkage, saving time and money. ECOFLEX-S should be applied to clean, dry surfaces, and with any adjacent surfaces protected from contact with the substrate. It should be stored above 40℉ and exposure to UV should be limited. You cannot apply a solvent-based product overtop.
