The invention discloses a precise control tool for improving the flatness of a cast-in-place slab and a leveling method. The precise control tool comprises an infrared gradienter and a precise leveling smearing tool. The fine flattening smearing tool comprises a smearing plate and a grab handle. The plastering plate is a bent plate, the inner concave face of the bent plate is used for plastering, and the outer convex face of the bent plate is used for mounting the grab handle. A sighting board for receiving a datum line is vertically arranged on the outer convex surface; a connecting part is arranged between the outer convex surface and the grab handle, one end of the connecting part is movably connected to the outer convex surface, and the other end of the connecting part is fixedly connected with the grab handle; an adjusting supporting part used for limiting the rotating angle of the bent plate is arranged at the connecting position of the grab handle and the connecting part, and the adjusting supporting p
