A spray polyurea elastomer which exhibits improved resistance to abrasion is disclosed. The elastomer includes an isocyanate, an amine terminated polyoxyalkylene polyol, a chain extender and a chemically sized filler material. The isocyanate is preferably a quasi-prepolymer of an isoyanate and a material selected from at least one polyol, a high molecular weight polyoxyalkyleneamine or a combination thereof. A method for making a spray polyurea elastomer which is substantially resistant to abrasion is also disclosed.
