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.
Claims28
A substantially non-slip coated substrate comprising:
- a solid film comprising a polysulfide, the film being spread on the substrate to form an exposed film surface;
- and
- a layer of elastomer particles between 0.3 and 3.0 mm average diameter partially bound in the exposed surface of the film, at least some of the particles projecting from the top surface of the film and not being coated with film material, said particles being softer than the solid film, the hardness of the particles being between about 45 and 95 Shore A.
A substantially non-slip coated substrate comprising:
- a solid film comprising a polysulfide, the film being spread on the substrate to form an exposed film surface, and the film being between about 5 and 50 mils thick;
- and
- a layer of elastomer particles partially bound in the exposed surface of the film, at least some of the particles projecting from the top surface of the film and not being coated with film, the particles being softer than the solid film, and the particles having an average diameter of between about 0.3 and 3.0 mm.
