When I layed self adhesive tiles in my kitchen and entry hall, the adhesive came up between some of the tiles leaving an ugly site. As you can imagine what it looks like when dirt sticks to it. It's almost impossible to remove. When I do, it just oozes back through. I mentioned this problem to someone working at Builders Square but he was not familiar with the problem. This is really the only type of flooring that is affordable for me and I like alot of the styles.
