I would like to make my garage wall a bit "smoother". And now I think about using drywall to cover the bare concrete. However the concrete is very uneven with at least 1 inch of concrete sticking out like in the corner below
(Sorry this pic turned side way)
The wall has several "lines" with metal wires sticking out. I could cut the wires but it will be hard to "sand" or cut the concrete.
What are your suggestion? Or should I "frame" 2x2 or something like that with plywood on the outside then?
