pva bonding as wood glue????

[rocco]

My friend at work says that you can use PVA bonding as wood glue! Is this true? PVA bonding is a hell of a lot cheaper than PVA wood glue!

Thanks

Hi Rocco

I fell for that recommendation a few years ago and used PVA bonding to glue the joints of a rabbit hutch. Each time it rained the joints turned white and the PVA Bonding reverted back to a liquid!

I guess it is better to spend a little more and purchase external PVA wood glue for gluing wood!

The answer is that there are PVAs and PVAs. The best are exterior grade, called D3, and the cross-link to make the glue curing process irreversible and pretty-much waterproof - ideal, too for kitchens and bathrooms. The next ones are D2, sold as interior grade PVA. You can steam the joints on these, but you don't normally do that in a living room, let's face it. PVA bonding is the lowest of the low and is as near to flour and water as you can come in the adhesives world (you did know that PVAs are all modified starches, didn't you?) - avoid like the plague for anything other than collages and scrap books! (and even then avoid.....)

Marvelous, a naysayer to the falicies of PVA, my personal pet hate, and not the answer to life the universe and everything.

Thought that was 42, or 54 or 6 times 9 base 13......... Certainly ain't 43, though ;?

Hi Rocco

Yes..... but a bit expensive if you're doing any sort of quantity. Like a bathroom cabinet.....
