Method of forming a decorative layer on a precast concrete board |
摘要 |
A decorative coating layer, unified with the succulent and fragile surface of a concrete board, is formed by a method comprising laminating an inorganic and hydraulic coating material on the surface of an unhardened concrete board placed in a mold, and immediately thereafter heat-curing the thus coated concrete board. According to this method, beautifully dressed precast concrete boards can be mass-produced by a shortened process with improved efficiency of operation.
