Description of the Related Art Cement mortar has been used as a material for joints of building materials such as tiles, large porcelain plates and stones used for the interior and exterior of buildings. However, joints using cement mortar tended to cause contamination that causes design defects such as adhesion of dirt due to water absorption from the surface and generation of mold. Further, as described in JP-A-8-165214, a joint construction method has been employed in which a joint material is cured for several days until the joint material hardens to form a joint, and then a photocatalyst is applied on the joint.

When an aqueous photocatalyst solution is used, it is applied before the joint material is cured, and the photocatalyst oxide is fixed to the surface by curing the joint structure. In any of these cases, the concentration is 0.1
It is desirable to set it to 50 wt%. If it is less than 0.1 wt%, it is difficult to exhibit a photocatalytic activity effective for preventing contamination, and if it is more than 50 wt%, the applicability to the joint material surface may be impaired. The application of a photocatalytic oxide to the joint structure surface increases the compactness of the surface, which is more effective.
