Hi. I want to extend some (2.5mm2) cable and intend to crimp the
connections (using a proper ratchet tool, before anyone says!). The
crimps will then be buried in plaster.

I'll be using the insulated blue butt crimps but would like to know if
extra protection is needed around them before sloshing wet plaster over
them.

Some heatshrink sleeving covering the whole joint would do no harm.
