PURPOSE:To obtain a material which can easily give three-dimensional stereopatterns and natural rock-like shapes a few cm thick of light weight to the surfaces of buildings and civil engineering structures for giving a fine view to these surfaces. CONSTITUTION:A foaming urethane resin composition comprising (A) the main material containing a polyether polyol, water and a catalyst, (B) a curing agent of an HMDI polyisocyanate, (C) a coloring material and (D) a filler is used in perforated mold frames. As a foaming type urethane resin composition is used, the material can be made thick with light weight and the admixing of colorants gives designingly beautiful three-dimensional patterns or shapes. |
