and more. Self stick tiles come in many qualities. I always do a sticky test with all tile before buying. if you peel back the paper and stick your finger on the sticky it should be strong enough to hold the tile on your finger suspended. Then too. get a good thick tile. those ones that are about 1/32 are soo thin that they will not last and will curl.
As with paint, the more expensive the tile the better the quality. in my opinion.
Also, make sure that the old tile is real clean and void of the smallest of debris as it will look like a mountain when the new tile goes over it.
