We want to put the same sticky tile over the existing tile just stagger them. Will that be unstable or should we remove the old ones...which seems like work lol
AS long as the old is stuck well, flat, clean of wax, should be fine . Good Luck
You need to remove the old tile.
As long as the existing tile is not cracked, has missing chips, free from grease and dirt and has been vacuumed you won't have a problem putting new tile over it. Also you want to make sure the existing tile is not loose in spots. Yeah, a few new tiles might lose their grip and come up.....in about forty years. We did the same in 1974. I am now in the process of a remodel and a few of them came loose. Must have been a bad batch of tiles! Lol. You'll be fine.
