Ply in rain

[Carl1991]

Hi all, I've just put a ply chip box on my new 4x4, but I'm awaiting delivery of some vinyl to wrap it. There's meant to be some poor weather coming next few days, will the ply last until the vinyl comes? Should be here Thursday. Don't want it ruined already. Cheers

If you have used weatherproof ply it will be fine.  If you have not it will be ruined by rain eventually whether you wrap it or not.

Should use Marine ply really . More expensive but...........

It's normal wbp exterior ply. I couldn't stretch to the marine just yet. Thanks

[Squaredy]

That should be fine then.

As I understand it, the only advantage marine has over wbp is it's resistance to salt water

You should be fine

 

Went for phenolic ply for our greedy boards. A bit less expensive than marine ply and has the advantage of one face being plastic coated and slippy. Exterior WBP ply holds up pretty well though

Thanks all. I'll probs get some sealer/varnish stuff tomorrow especially for the edges, then I'll wrap it, round the corners too then probably put some 20mm angle all round. 8x4 sheet of marine was 70 odd quid, the ply I got and 2x2 was around half that!

You could maybe duck tape the exposed edges to keep the worst of the water out.

My experience of WBP is that it warps and delaminates unless the edges are sealed oreven better capped. You can get aluminium U capping strips that fit snugly around the edge and keep the laminates together and the water out.

i did a chip box like this once and it outlasted the cabstar!
