A solid golf ball comprising a solid core, an encapsulating coating having a thickness of about 0.001 to 0.01 inches and a cast polyurethane outer cover layer. The cast outer cover layer is comprised of a prepolymer and a curing agent, wherein the prepolymer is made from a polyol selected from the group of polyether, polyester and polylactone and a diisocyanate selected from the group of 4,4'-diphenylmethane diisocyanate (MDI) and 3,3'-dimethyl-4,4'-biphenylene diisocyanate (TODI) and toluene diisocyanate (TDI). The encapsulating coating is a thermosetting latex material that is applied to the solid core through a solution.
