Abstract
Abstract A substantially non-slip, non-abrasive surface which includes a layer of a coating vehicle comprising a polysulfide mixed with a plurality of solid elastomer particles. The particles are preferably at least partially embedded in the coating composition to provide a surface which maintains tractional sufficiency in wet and dry environments such as swimming pools and related areas.
