Exterior Ply

[empty-seat]

I need some timber sheets for an outdoors project, and I'm struggling to find something suitable.

A visited the local DIY stores and the Plywood rated for exterior use seems crap. The laminated sides seem to separate and peel off really easily, and I can't imagine it holding up when I cut it, so I've resisted buying anything so far.

I will be painting it - could I just use regular good quality structural plywood sealed with paint? Or is this likely to deteriorate rapidly in the rain?

Thanks a lot for your help, I really appreciate your guidance.

I wouldn't. Any damage to the paint i's going to result in a much bigger issue for you. I have always found marine ply from my local wood yard pretty good but then I don't know how good it must be for your project. I wouldnt buy from a diy store on price alone despite the questionable quality

OP - what do you want it for?

DIY stores are the wrong place to look for quality ply.

I seen and used a full bale of 13mm marine ply from a reputable hard ware distributor and it had bubbles and the laminates were not bonded that well.
Chinese it turned out!

Which is why so many buildings have gone over to cement board, I'm sure.
