Sanding concrete walls with a giraffe?

[ravve007]

Hello,

This might be the dumbest question of the day...

My basement concrete walls are a bit uneven, and I would like to even them out. Can this be done by grinding down the uneven spots, for example with a giraffe sander, or does it need to be skimmed first and then sanded? In other words, is there no way to avoid the spackling?

A regular giraffe is of no use on a concrete wall, but there is a special version for grinding it.
