What waterproof material to top an outdoor DIY potting bench- cheaply?

[miljee]

I am planning on building a 'potting' bench using old pallet wood, but the void beneath needs to be weatherproof because I will be storing an electric lawn-raker under there. I plan on covering the sides with shiplap planks, but as for the top, other than the obvious, a sheet of metal (££), what do you think I could use? It would be handy if the surface was reasonably easy-wipe to clean up after I've done some potting on it!

Any ideas?

perspex or similar but you will need an angle so the water sheds off rather than run underneath

Anything decent will cost you - any ply type timber will soon delaminate.
How about some aluminium checkerplate? Second hand yards could be a pal here.

Thanks both- yes, I am thinking I'll put a bit of a slope on the top, maybe 1" or so to assist run off.

The distressing thing is that my dad, RIP, had several large sheets of copper (he made clocks as a hobby) that would've served well...

You could get a sheet of 3mm pvc cladding used for commercial kitchen walls etc relatively cheaply. Its hard but will scratch a bit

Ah, that's a good idea, too! Had no idea it existed!
