I did follow your links. The first one says put some wood in with it to absorb moisture. The second link has a PVA glue and a urea-formaldehyde glue. Both are water based so still need some evaporation to set.

The glue Mekanik linked to is a PVA like the 'EasyBond D3' in the Airpress website. I don't see how this is going to be any different than the PVA I already tried (Polyten).

I've ordered some powdered urea-formaldehyde glue. I think this breather mesh sounds like a good idea to provide a bit more air for the glue to set. I also wonder if some of those silica-gel packs would help.

Yes, but not only that it tells you all about how to do the job with a breather mat etc.

Hi Tenson
If you look @ my setup you will see that the veneers are covered in a blue material, this is a plastic mesh that i use for doing vacuum infusion jobs, if you go to any online dealer that sells infusion resin you will find some there, the white tubing is spiral wrap. cheapest place to get this is Maplin(or it was when i bought mine) it's used for holding loose wires to tidy them up.
If you notice you will see the glue extruded through the joints between the veneers. This was a trial run to see if i could make a half decent job of it as i intend to do all my sills the same (the windows are Iroko also)
Hope that helps and good luck with your next shot.

So you are putting the breather mesh on the veneer side?

[mekanik]

Yes, the veneer is then subject to full Atmospheric pressure.

Any PVA glue should work fine. I'm guessing that you either didn't use enough, glue, you didn't get it in the bag fast enough, or you didn't have enough pressure.

I generally use Titebond Cold Press veneer glue, as it gives a little longer working time. I only leave it in the bag for 90 minutes, and never use breather mesh. I always use a hard caul over the veneer, though.

I've also had good results with plastic resin glue, which comes in powder form and is mixed with water.
