Abstract

The present invention provides coated sand that has excellent water permeability and excellent releasability from a molding die when molding a casting mold. The coated sand also makes it possible to obtain excellent strength in a casting mold obtained as a final product. The coated sand is in a dry state, is fluid at room temperature, and is coated by a coating layer in which the surface of a fire-resistant aggregate contains water glass as a binder. The coating layer contains a surfactant.
