Should I use lime wash as part of my C&D programme?
Lime wash is cheap and cheerful and good for making surfaces smoother e.g. where concrete is beginning to pit. It has some antimicrobial action, but you need to thoroughly clean AND disinfect before applying. Once applied it must dry for at least 48 hours.

H&S needs to be considered: You need full protective clothing, including a
mask and goggles as it is an irritant and corrosive and will burn skin and oral
mucosa. There was a suspect case of Foot and Mouth Disease which turned out to
be lime burns (blisters on feet and udderline in a farrowing crate). Preparing
the surfaces for the limewash is the standard you should be looking at in your
routine cleaning and disinfecting, so if walls are still in good condition, an
additional disinfect and/or some dry disinfectant should be adequate.
