<p>The present invention relates to a coating composition and top coating composition, wherein the base coating composition consists of 5 to 35 wt.% of the white cement, 20 to 50 wt.% of the calcium carbonate, 5 to 35 wt.% of silicand, 5 to 35 wt.% of slag, 3 to 25 wt.% of the powdery redispersible resin, 0.05 to 0.3 wt.% of the thickener, and 0.1 to 0.5 wt.% of antifoaming agent; and the top coating agent consists of the silane derivative, colloidal silica and water soluble lower alcohol and water. The base composition consisting of the inorganic material except the redispersible resin shows the excellent binding strength and does not show the efflorescence phenomenon and peeling of the coating material from the surface of the tile or top coating composition consisting of silane derivative, colloidal silica, etc. shows the excellent binding strength and ventilating property after coating.</p> |
