So my dad tried a DIY birch plywood floor over concrete in his studio and it really hasn't worked out. Most of the corners of the boards have since warped and curl upwards of 4 inches. So he's considering putting down a laminate. That is, until we discovered that Ikea is selling a "real wood" version of their laminate, called Balk.
So the main question is: does anyone have any experience with it? Anyone know if it's any better than Pergo? And does anyone know whether we'd be able to install either over the pre-existing warped floor (that we would bolt and/or secure down?
