We bought our house and there is a shed in the yard that was 2 sheds right next to each other. It was recently torn down (not by me) and rebuilt. It's nice to have one single space the only problem is that the slabs were poured differently. One slab slopes from down from right (0") to left (1.5"). I've looked at various self leveling concretes but they say that they are not a wear surface. I believe that this would be too thin to pour with regular concrete on top of this. I've looked at some products such as this but would appreciate everyone's input. Also if I could do it cheaper but in a lasting way that would be great too.
