Our bath vinyl sheeting floor is in excellent shape. What do people think about us having it put over the vinyl? Does something need to cover the vinyl first? The floor is very straight and the vinyl w/out problems. If not, what do you recommend? Thanks!
If it's on concrete and firmly glued down, it shouldn't be a problem to just install over it. If you're installing over vinyl attached to a sub floor, that requires a little more work. You need to screw down a half inch concrete board before tiling. Make sure you use screws that won't rust. If that makes the floor too high, they do sell some thinner material that's just as strong. You just need to make sure the floor doesn't have bounce or you'll end up with cracked tile or mortar.
