Treated Timber & Glue

[Obi Wan Kenobi]

Sorry about this, but a basic question from a 'simple' person :roll: Still, I'd rather ask and get it right, than balls up a lot of work for being too proud to ask

I have some C16/C24 treated timber that I may use shortly for a couple of builds, and simply want to know if I can use normal PVA for the glue up.

Many thanks in advance.

Yes, as long as the wood's dry, i.e., below 20% MC. Freshly treated wood is generally sopping wet, but as long as there's been time for it dry out PVA should be fine. However, being construction grade wood you're working with it's possible your construction's application may also be subject to high levels of moisture in service - not all PVA adhesive types are either water resistant or waterproof. Slainte.

Thanks SD, that's good to know. The wood is very dry and I take your point about the type of glue to use.
