ECOFLEX-R is designed as a moisture and vapor barrier membrane for cavity wall construction that may be applied on a variety of surfaces, including concrete, concrete block, metal, and dense glass. It should be applied by roller or sprayer to form a monolithic air barrier. It can also be used as waterproofing adhesive for insulation board and as a base coat for other water-based coatings. ECOFLEX-R is a medium viscosity water-based, polymer-modified anionic bituminous/asphalt emulsion, which exhibits excellent bonding, elongation, and waterproofing characteristics and is non-hazardous, non-toxic, and non-flammable (VOC compliant). ECOFLEX-R is not affected by ponded water, and it may be applied to green or uncured concrete and damp surfaces. Its rapid setting allows the job to be completed in one application, making it highly efficient.
ECOFLEX-R 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. During warm weather, application in 20-mil layers is recommended. You cannot apply a solvent-based product over the top.
