Veneers popping and glueing problems
"One flop so far, the Huon Pine popped off like it never seen glue! "
Huon Pine contains a lot of oil. Bit like teak and both timbers can be hard to glue.
The oil on the surface of the prevents the glue to penertrate into the pores of the wood.
I once glued teak to a fibreglass deck on a boat with an epoxy glue and just before applying the glue I wiped the wood surface with acetone which removed the oil for a depth enough for the glue to penertrate. Did some sample test before finishing a 30 ft deck.
All my glueing of Huon I've used the same priciple and it works Animal glue expoy what ever.
Normal PVA not so good but better class PVA OK.
This applies to many other timber species which have high oil or tannin content.
Years ago Gluelan Beams made fro WA Karri failed after some years in service and it was found that glues did not penetrate into the timber.
Acetone Meths IPA can be used but needs some testing before using.
Hope this helps
