    摘要: An exposed aggregate finishing method for concrete. The method comprises coating the inside faces of a form for concrete with a cement setting retarder, drying, coating the dried faces with a synthetic organic polymer coating material which is soluble in an aqueous alkaline solution of cement, but is insoluble in water; and drying the coated faces. Alternatively, the method may be carried out by coating the inside faces of the form for concrete with the mixture of the cement setting retarder and the organic polymer coating material and drying the coated faces. Concrete is thereafter placed in the concrete form, the form removed and the surface of the molded concrete washed to make the surface rough.
