Exterior board what's the best

[SteveP5B]

Hi folks, I'm looking for advice as to what board will last the longest against the elements. It's for use in the garden as a piece of " garden art"and will be painted.
This is one I made years ago and needed painting every year but the ply used has deteriorated and now flaking.
Thanks Steve

Look at Magnesium Oxide boards such as www.econicboard.com, or a wood-bonded cement board such as www.euroform.co.uk/versapanel_what_is.shtml

Some products I've not seen before, thanks for the links. Guessing the cost will be high, more than marine ply?

No they are less than marine ply - less than £30 an 8x4 sheet in 12mm

Thanks, I'll track some down.
