RHOA Sealer™ is a high-performance protective coating designed to preserve and enhance RHOA Plaster. Unlike acrylic sealers, it penetrates the surface to provide long-lasting protection without altering the natural appearance of the finish. Formulated to maintain the raw, architectural concrete aesthetic, RHOA Sealer protects against moisture, stains, and surface wear while allowing the material to breathe. It enhances subtle depth and tone without adding gloss or artificial shine—keeping the finish true to real cast concrete. Each bottle is designed to pair with one bucket of RHOA Plaster (24 sq ft coverage), completing the RHOA system alongside Primer, Plaster, and Film for a durable, protected, and refined final surface.
