Currently I have the task of finishing a golf range in a basement. That part isn't too much of a problem. However, about one and a half of the walls are cement walls. I'm curious as to what might be a cost efficient and durable covering for those walls. The wall hasn't been framed and it's just a concrete slab from the concrete floor to the wooden I beams. The golf range is going to have net, so I don't think that the wall will have to be able to take any direct hits, and the wall is about 20 to 30 feet long about 12 feet high. Thanks.
