Yes. SRW Rapid-Set Polyurethane can be used on wood, metal, natural stone and clay. On steel surfaces, make sure there are no oils which will deter the adhesive to stick. Quick Tip: for faster set up on steel and aluminum, scratch the surface. Not for use on plastic, rubber, fiberglass or materials designed for continuous submersion under water.
