Rust-Oleum® Tub & Tile Refinishing Kit features an epoxy coating that lets you refinish bathtubs and surrounding tile without the time, cost and inconvenience of a professional remodel. The bathtub coating can be applied to ceramic, porcelain, fiberglass, cast iron, steel and certain acrylic surfaces including tubs, shower walls, backsplashes and sinks. It delivers an ultra-hard, durable finish that looks like porcelain and ceramic.
