Inorganic reaction type water repellents include, for example, free calcium hydroxide which is promoted by a highly reactive catalyst and causes an inorganic solution to cause efflorescence, and silica which causes an alkali-aggregate reaction. A substance that generates a stable hydrophobic inorganic substance by reacting with the substance and the like, and the hydrophobic inorganic substance fills voids and water in the calcium silicate plate is used. By reacting with the inorganic solution to become a stable hydrophobic inorganic substance, factors that cause efflorescence and neutralization are removed, making it difficult for the reaction that causes the deterioration phenomenon to occur. By filling the pores and water gaps, the strength and rigidity are increased, and water repellency is further exhibited. Further, since the water repellency and the anti-deterioration property are exerted by a chemical reaction, the effect is maintained for an extremely long time.
