Resilient surfaces are provided, which are easy to apply and have excellent tensile properties. A castable mixture is prepared combining a nonvolatile oil-based extender, resilient aggregate, carbon black, and a polyurethane prepared from diols, the major portion of which is a diol of from about 1,000 to 5,000 molecular weight, wherein the hydroxyl groups of the diol are joined by long-chain hydrocarbon groups substantially free of hetero atoms in the chain itself. The resilient surface sets up quickly to a useful surface and will generally be no greater than about 2 inches in depth.
