Sloshed paint is out of place (5)
I believe the answer is:
inapt
'out of place' is the definition.
(I've seen this before)
'sloshed paint' is the wordplay.
'sloshed' indicates an anagram.
'paint' anagrammed gives 'INAPT'.
'is' is the link.
(Other definitions for inapt that I've seen before include "unqualified" , "badly judged" , "Out of place" , "Ill-suited" , "not seemly" .)
