Hi, I'm replacing some of the wood on the vertical slats in my verandah railing. A few have been infected by some kind of fungal rot, so replacing those. They are 30mm x 30 mm X 500 mm. My question is, as these are external bits of wood, is it OK to use a pine like this? use https://www.bunnings.com.au/porta-30-x-30mm-1-8m-moulding-pine-dar-standard_p0021343
And what would I need to treat it so it residents fungus and is weatherproof?
Cheers and thanks.
Mike
