の防水性塗料で表面化粧することが行われていた。2. Description of the Related Art Heretofore, ceramic plate materials made of fiber reinforced cement have been very widely used as exterior wall boards. The seed wall plate having the same shape can be mass-produced at low cost, and consumes almost no natural resources such as wood, so that it is advantageous from the viewpoint of nature protection. By the way, since these ceramic board materials have surface water absorbency, if they are left as they are, the waterproofing effect is not sufficient, so in the conventional case, the surface makeup is performed with waterproof paints of various colors for the purpose of suppressing surface water absorbency and at the same time imparting designability. Was being done.

There was such a problem.
Then, when such deterioration occurs, the waterproof function is gradually impaired, and there is a problem that the deterioration due to freezing and thawing is further promoted in a region where the backside of the wallboard has permeated with water and mold develops.

The texture of the ceramic base material itself, that is, in the case of a fiber reinforced cement board, the color peculiar to cement hydrate, the state of efflorescence due to the precipitation of calcium, and the appearance of the mixed aggregate as it is. It was made to appear. The fiber-reinforced cement board is formed from a compounded material to which 5 to 40% by weight of colored silica sand or glass beads is added. These coloring additives are for coloring the fiber-reinforced cement board. If the amount is less than 5% by weight, the coloring effect cannot be obtained, and if the amount is more than 40% by weight, the bonding strength of the cement matrix is adversely affected.

系板材はシーラー塗布の時点で表面吸水性が無くなる。The surface of the ceramic plate material is first coated and impregnated with a penetrating water absorption inhibitor to suppress surface water absorption. A silane-based impregnating agent or a polyurethane resin-based sealer is used as the penetrating water absorption inhibitor. Since these permeable water-absorption inhibitors are impregnated on the surface of the ceramic plate material, the ceramic plate material loses surface water absorption at the time of applying the sealer.

ビーズであるから褪色の恐れは殆ど無い。Then, the sealer coating surface is coated with a fluorine resin, acrylic urethane or alkoxide type weather-resistant clear coating so that the texture of the substrate itself is maintained for a long period of time. It should be noted that since no clear pigment for coloring is used in this clear, there is no problem of fading due to ultraviolet rays. The color of the fiber-reinforced cement board itself is inorganic colored silica sand or glass beads, so there is almost no fear of fading.
