A refresh is livening up and boosting condition
A renovation is restoring to good usable condition
A refurbishment is enhancing to increase value or lifespan
Routine repainting, and renewing worn flooring and covers is not refurbishing

I completely agree with this, and would add that in BR days there were laid down repair standards, C1, C2, C3, C6 which clearly laid down what was done - nowadays anything seems to go depending upon what is actually specified each time a repair is required ! Some people even within the industry seem to regard a simple lick of paint and a clean up as "refurbishment" - this of course is sheer rubbish !!
