I also cannot believe that is what Armstrong said. I have no connection with them but have owned Armstrong flooring that was installed by a dealer who sold armstrong flooring for about 35 years and in fact, nothing that we didn't do to it ever happened. It went out of style first. They do have different qualities (E>G years ago Solarian was the top of the line). Was this bought at a superstore and an installer they recommended put it in? Wow.
