A one-step method of treating a surface to increase its coefficient of friction without pretreating the surface or rinsing or removing a treating solution, utilizes an aqueous solution of ammonium bifluoride, and allows the solution to remain on the surface until the surface has dried. Preferred methods of application are applying the solution with a mop, by wiping the surface with a rag treated with the solution and by applying a mist of the solution onto the surface.
