I've just veneered a sheet of birch ply (one side ash, one side ash
burr) and when trimming the edges in places the veneer flaked off the
glued surface. I think that I could probably peel chunks off, a bit like
a nasty bit of far eastern ply.
Inevitably I'm wondering what I did wrong.
The panel is ~700 x 250 mm. Glued with cascamite, applied with a toothed
spreader then went over it with a sponge roller (apparently it's
important not to have too much glue as it can push through the veneer).
With the veneer positioned I placed it on a piece of MDF and then
stacked a pile of MDF sheets on top.
My guess is that there wasn't enough pressure to force a thin glue line:
(i) more pressure; and/or
(ii) mix the glue a bit runnier.
Am I on the right track? If so how much pressure am I going to need?
Curved cauls + cramps? Vacuum bag??
Is there something fundamental I've missed??
And am I right in thinking that this piece isn't usable :( as the
veneers could delaminate in the future?
The only time I used Veneer was about 25 years ago. Covered all the interior
doors and door trim with mahogany. Used contact cement. All is still intact.
