Is the tile binder good? Does it contain formaldehyde?
Because cement mortar construction, resulting in the phenomenon of tile off more, and later maintenance is also more troublesome, so I suggest we still use ceramic tile adhesive bar.
Of course is to use ceramic tile adhesive tile paving tile adhesive better ah, paving tiles not hollowing, cement mortar cost is relatively high, but the cost of labor, cost saving and property maintenance.
