看起來像混凝土現場灌漿，實際上利用GRC做成本色，再後加工噴塗，事實上在工廠也可以直接上色，但許多人擔心安裝時候會損害到產品的表面或是接觸面，因此都會選擇後加工現場再噴塗，事實上這樣的工序不會比在工廠上色的完整性還要高
It looks like concrete on-site grouting. In fact, GRC is used to make natural color and then processed and sprayed. In fact, it can also be painted directly in the factory. However, many people worry that the surface or mounting contact surface of the product will be damaged during installation, so they will choose post-processing on-site and then sprayed finished such a process will not be better than the integrity of coloring in the factory
