Hi,
A year or so ago I built myself a speaker enclosure from MDF. I glued and screwed the joints, the joints were filled with U-POL P38 filler. After the glue was set I removed the screws, drilled out and filled with dowels. Everything was sanded down and then I sealed the MDF with watered down wood glue. The finish I was after was a high gloss black, I'm no expert just a DIYer but I was pretty happy with the finish.
Anyway to my question, about 5/6 months after painting the joints began to appear, these had sunk, and where the dowels had been placed, these began to looked raised.
Below are a couple of pictures which show my issue.
I'm now thinking of making a new box but I don't want to make the same mistakes.
Instead of using screws then replacing with dowels I can use internal batters to construct the box.
Regarding the joins appearing I've read a few posts here and using a wood hardener seems one possibility that may help, the posts I read are quite old so I was wondering if there is a better approach that I can take to try and minimise this?
Any advice would be welcome.
Thanks,
Marv.

An externally hosted image should be here but it was not working when we last tested it.
