PROBLEM TO BE SOLVED: To provide a super water-proof anti-bacteria and anti-pollution paint for protecting surface of a thing. SOLUTION: This paint is prepared by compounding an ethyl silicate and a silane coupling agent to a mixed alcohol solution carrying a dispersed photocatalyst, titanium dioxide and silicon dioxide, and combining an isopropyl alcohol in which a polyalkyl siloxane compsn. and a methylmethoxy siloxane are dissolved to the former solution. An example of compounding contains 1-10% titanium dioxide, 2-3% silicon dioxide, 10-15% ethanol, 55% isopropyl alcohol, 2-5% methanol, 3-5% ethyl silicate, 3-5% silane coupling agent, 0.3-0.7% polyalkyl siloxane compsn., 3-5% methylmethoxy siloxane, and 2-4% toluene. In this method, hardness of coating, strength of photocatalyst reaction, and hydrophobic property are freely changed by changing the compounding ratios of ethyl silicate, titanium dioxide, the polyalkyl siloxane, and the methylmethoxy siloxane.
