If the test is qualified, the flexible ceramic composite tile is pasted on the paint layer; otherwise, the original paint layer and putty are completely removed, then polymer cement mortar is used to level the surface, and then the flexible ceramic composite tile is pasted. When the base of the wall surface is an old insulation layer, first check and repair the hollow and cracked parts of the old insulation layer, and then paste the soft porcelain composite tiles. When the wall base is an old wallpaper finish, remove the original wallpaper, clean the surface, and then paste the soft ceramic composite tiles. When the base of the wall is solid wood or composite wood, waterproofing treatment is applied to the wood surface before soft ceramic composite tiles are pasted on.
