Seam cleaning: when the splicing method is adopted, because the thickness of the flexible clay tiles is only 2 ~ 3mm, it is necessary to carry out the joint cleaning treatment to facilitate the filling of the sealant paste. If the joint is not cleared, the normal joint filling and pointing operation can not be carried out after the joint adhesive is dried. The joint cleaning operation must be completed after pasting and before the initial setting of the adhesive.
