A method of providing a textured surface to the floor of a refrigerated storage enclosure. The steps include applying a layer of resinous material over the surface of the floor, the surface being formed of a hardened material, placing a single layer of sand on the layer of resinous material, and applying a layer of clear epoxy resin over the layer of sand. The layer of sand is evenly applied, and the layer of clear epoxy resin applied over the layer of sand is permitted to harden.
