Hand over plaster covering (6)
I believe the answer is:
render
This clue could be a double definition.
'hand over' is the first definition.
(synonyms)
'plaster covering' is the second definition.
'render' can be an answer for 'plaster'. I am unsure of the 'covering' bit.
Can you help me to learn more?
(Other definitions for render that I've seen before include "Hand over; plaster" , "Cover with cement" , "Yield or clarify by melting" , "Give performance or melt down fat" , "Give brickwork a coat of plaster" .)
