PURPOSE: To facilitate removing work of cement paste by coating the whole surface of a tile and a part of the side of the tile continued with the surface side by cement paste removing material to which cement paste is hard to stick.

CONSTITUTION: Cement paste removing material 2 to which cement paste is hard to stick is coated on the surface 1a and a part of a side 1c of a tile 1 for a tile previously hanging method. The tiles are arranged on one plane so as to face the surface 1a of the tile upward, temporary joint filler is filled in the gaps between respective tiles 1, a one side sticking film 3b is stuck on the tile surfaces 1a, and hence a tile unit 3 is formed. Consequently, stuck cement paste can be removed in a short time.
