Cuts back on company making fine plaster (6)
I believe the answer is:
stucco
'fine plaster' is the definition.
(I've seen this before)
'cuts back on company' is the wordplay.
'back' shows that the letters should be reversed in order.
'on' means one lot of letters go next to another.
'company' becomes 'co' (abbreviation).
'cuts' backwards is 'stuc'.
'stuc'+'co'='STUCCO'
'making' is the link.
(Other definitions for stucco that I've seen before include "Kind of plaster used for wall decoration" , "Plaster for coating or moulding" , "Decorative external plaster" , "Plaster used to coat walls" , "wall-covering" .)
