Any ideas to tart up the inner walls of a single concrete
block workshop ?
A coat of paint would be better than nothing but the blocks
are very coarse. I was thinking of something thicker to skim
or paint on, smoothing out the surface.
BTW I'm no good at plastering and a workshop doesn't
justify a prof. job.

You could try an artex like compound. Seal the wall first with dilute
PVA and allow to dry first otherwise the artex will dry before you can
smooth it out.
If you are not confident about getting a smooth enough surface you could
always get artistic with an artex comb?
