Thread: Need to seal cupboard frame?

I'm building a linen cupboard in a large alcove in a house with drywall that's gyprock over thin metal framing, so the cupboard must be entirely self-supporting. I'll just plaster the front to fit in (above the doors).

As a fairly agricultural carpenter, there's a minimum of smart jointing. I'm using Meranti for most of the framing, Melamine shelves (1,600 x 600 x 20) and a few bits of Jarrah for the door frames and some rigid uprights.

This is all wholly internal timber and the Jarrah will be painted.

Do I need to do any kind of sealing of the structural Meranti?

What about the edges of the Melamine - I had to saw all the shelves to fit so there's one side that is a bit coarser than the others.

It is in a very dry area.

thanks

Andy
