Spread glue (5)
I believe the answer is:
paste
I believe this is a double definition.
'spread' is the first definition.
('paste' can be a synonym of 'spread')
'glue' is the second definition.
('paste' can be a synonym of 'glue')
(Other definitions for paste that I've seen before include "sound beating" , "foie gras" , "Food prepared for spreading" , "not real rock" , "An adhesive, or material for artificial gems" .)
