In the decoration mat of this invention, a large number of colored particles are distributed on a rugged pattern transfer surface through an adhesive layer the bonding power of which decreases upon water absorption. A method of forming a pattern on a concrete surface according to this invention comprises pouring a concrete material using the rugged pattern transfer surface of the decoration mat as a contact surface with the concrete surface, reducing the bonding power of the adhesive layer by the moisture of the concrete material, transferring and burying the colored particles into the concrete surface, and forming the concrete surface into the rugged pattern surface by the transfer of the rugged pattern transfer surface. In the method of this invention, the bonding power of the adhesive layer is reduced by the moisture of the concrete material during aging and curing after pouring, and the colored particles retained by the adhesive layer are transferred to, and buried into, the surface layer of the concrete material. Accordingly, colors of natural color tones can be expressed on the surface layer of the concrete molded article. Since the colored particles do not undergo discoloration, fading and deterioration, a rugged pattern retaining high durability for a long time can be obtained. <IMAGE> |
