  • Terra Alba Wallpaper was manufactured by coating inorganic terra alba paint on white base paper, and the surface of the coated layers were microscopically observed. Eco Terra Alba used the functional wall paper in this study was prepared by mixing inorganic Terra Alba and calcium carbonate. Terra Alba showed particle shape. The concentration of inorganic components, pH, and the viscosity of the coating solution were 92.0%, 7.82, 1286 cPs, respectively. The bar coater whit No 3 wire resulted in the least thickness of wet coating layer and coating thickness such $22.5{\mu}m$ with covered all the surface. Bar coater with No. 12 wire leaded to $48.4{\mu}m$ thickness. The coating layers above $43{\mu}m$ thickness showed the cracks on the wall paper surface after coating.
