Stagger back from park with painting (6)
I believe the answer is:
recoil
'stagger back' is the definition.
(I've seen this before)
'park with painting' is the wordplay.
'park' becomes 'rec' (I've seen this in other clues).
'with' is a charade indicator (letters next to each other).
'painting' becomes 'oil' (oil painting is a kind of painting).
'rec'+'oil'='RECOIL'
'from' acts as a link.
(Other definitions for recoil that I've seen before include "withdraw" , "Spring back suddenly as gun may when fired" , "Kick of gun" , "Cringe" , "Quail is here!" .)
