Dealing with the seam between butt jointed MDF

[chris-s]

I've got to do some butt joints with 18mm MDF, the parts fitted to a very rigid frame so will not twist or flex, the edges will be fully sealed, and the face will have a multiple layers of primer, paint and gloss top coat.

I can't help but feel the joint will show thru and that I should do something like run the router down the seam and back fill with filler, maybe even an epoxy based filler?

Suggestions greatly appreciated.

Thanks, once again!

Provided the joints were cut cleanly in the first place, you use a decent adhesive and dowels/biscuits to reinforce the joint it will not show.

If after sanding there are any gaps use an epoxy filler (car body filler)
