A floor mat has a slip resistant upper surface intended for foot traffic and a backing layer intended to lay across a surface on which the floor mat is supported. The core of the mat is a woven roving sheet of fiberglass. A layer of polyurethane is bonded to the fiberglass, and beads are projected to impact the polyurethane layer when it is soft and tacky. The beads are sintered ceramic beads having a high coefficient of friction. At first, the beads are partially embedded in the polyurethane layer, then the polyurethane is heated to further embed the beads to 60-90% into the polyurethane. This leaves the crowns of the beads exposed, and in combination with the intervening expanses of polyurethane provides a slip resistant surface.
