Hello Dear Customer, There are things to be careful about when pasting the product, if you pay attention to these points, you will not have the problem of falling off. First of all, the floor wall to be pasted should not have rough tiles, make sure it is a flat, smooth and clean floor wall. Then remove the transparent protective tape behind the hanging tapes, make sure it is well ventilated when sticking, and you can start using it after waiting for 24 hours. Thank you for choosing us and we wish you pleasant shopping.
