Thanks, I have some MDF sealer and various primers (adhesion/multi surface etc) The other option I thought of was borrowing a small hand router thingy and putting a neat 45° edge detail on the boxes as this is what I had done on a MDF pelmet at the top of a window reveal where we need something substantial to screw the secondary glazing into, it’s what the carpenter suggested as mating a piece of MDF to a plasterboard corner is impossible as it just moves.
Finishing off with Toupret FSF is a good idea.
I would still rather do this job with a Stanley knife/cutting mat/glue gun though!?
