Plasterwork (6)
I believe the answer is:
stucco
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">plasterwork</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I have seen 'Decorative plasterwork ' mean 'stucco' so perhaps 'plasterwork' could also mean 'stucco')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for stucco that I've seen before include "Fine plaster for ornamenting walls etc" , "Fine plaster used on wall surfaces" , "Coating material" , "Plaster for coating outside walls" , "Kind of plaster used for wall decoration" .)
