To transfer wrinkle patterns of crepe paper to the surface of concrete without applying time-taking coating to the inside of a form by forming mold transfer paper from crepe paper obtained by creping paper to which water repelling treatment is applied.
Mold transfer paper for concrete is formed from crepe paper obtained by creping paper to which water repelling treatment is applied. This water repelling treatment for forming the crepe paper is performed by using a material used as a water repelling agent of paper such as a paraffin wax emulsion or a silicone emulsion. Further, a material prepared by compounding a synthetic resin emulsion such as synthetic rubber latex, an acrylic resin emulsion or a polyvinylidene chloride emulsion with the water repelling agent is used and it is desirable to form the film of the synthetic resin emulsion on the crepe paper from such an aspect that the releasability with concrete is large.
