What is the proper adhesive and procedure for glueing up some 3/4 veneered
MDF? The veneer is so thin that if I tried to clean up any squeeze-out I

looking in the wrong spots but after a google search I found nothing helpful.

thanks!

G'day Pierce,
If I read this right - you have 3/4" veneered MDF board and intend to
make right angled joints that will mitred !!.
I have done quite a bit of work with veneered board, both chippy and MDF.
The norm is to glue it with PVA and wipe any excess with a damp cloth
(Damp not wet)
Now for the hard part, the corner.
What ever you do do not sand that corner with anything greater than 120g.
Only touch it so as to put a small arris on the corner and remove the
sharpness.
To sand the flat use a sanding block, either cork or a shop bought one.
A scraper can come in handy to, but keep it flat, especially when close
to the corners.
While doing my apprenticeship this was the hardest type of joint to
learn to do properly and it has been the hardest to teach to apprentices.
These days, my preferred route would be to use 3/4" filler strip of
matching or contrasting timber in the corners, either dowel or biscuit
the board to it.
hope this helps a bit.
Just take you time and all should be well

regards
John
