Opus Easyseal AC3 is a specially formulated clear acrylic resin polymer compound designed specifically for the initial curing of freshly placed concrete, combined with the added benefits of sealing, hardening and dustproofing the concrete surfaces. Opus Easyseal AC3 is a partially penetrative material which provides a permanent, non degrading protective matrix to the concrete surface. The acrylic film is UV stable and once cured provides a durable elastic coating which provides protection against staining and subsequent dusting.
