I have seen a few of the other responses to this question and I have to ask "is anything really permanent?" I am having a hard time believing that anything that is painted on top of a surface that has been baked and sealed could be permanent. I would love to try this in my new home but with dogs, cats, kids and a lot of furniture that moves around on the floor I can't help but think that this newly painted surface would eventually scratch off. I hate the thought of tearing up and re-tiling 2400 sq feet of floor so if there is anything that is totally fool proof I am ready to listen. Thanks.
