Abstract: A loess finishing material is provided to contain neither formaldehyde nor organic solvent, to suppress the occurrence of a bad smell during/after construction, to emit far infrared rays, and to improve worker's workability. A loess finishing material using a two-solution type water-borne adhesive includes (A) a water-borne adhesive base material, (B) a hardener containing an isocyanate compound having an NCO content of 25-35%, (C) an inorganic filler, (D) a loess powder, and (E) water. The water-borne adhesive base material contains (i) 20-100 parts by weight of rubber latex or emulsion resin, (ii) 5-50 parts by weight of an OH group-containing polymer aqueous solution or emulsion, (iii) 5-100 parts by weight of an inorganic filler, and (D) 1-20 parts by weight of an additive. Further, the emulsion resin is one or more selected from water-soluble acrylic resin, ethylene vinylacetate, polyvinylchloride, polyvinylacetate, poly butadiene, poly vinylidene and polyurethane.
