How can a cinder block wall be covered up on the interior in a simple fashion - some kind of plaster or covering? Assuming low skills, can the unevenness of cinderblocks be dealt with somehow short of installing wallboard?
BTW, this wall is never cold, only too hot. So no condensation issues, but insulation could be a plus. Heard of some kind of plaster mixed with styrofoam particles being used for exteriors in Arizona adobe houses - may be a help if I could track some down. tks
