摘要

PURPOSE:To protect the coat and the plate member from strong sunshine, intense heat, wind and waves, and the like, and enable durability to be extremely improved by forming an adhesive layer and a smoothed glass layer on the surface of the plate member with the main material of cement. CONSTITUTION:A plate member 2 with the main material of cement is formed, and its surface is coated with adhesive 3, and an adhesive layer 4 is formed. After that, on the adhesive layer 4, low temperature melting glass powder 6 is applied roughly uniformly to be fixed, and is heated by a heating means, and the surface section of the low temperature melting glass powder 6, at least is fused to be smoothed, and a glass layer 5 is formed.
