Damp Proof Membrane (DPM) - why the different colours?

[Eric The Viking]

I want some tough waterproof sheeting to go under a woven one-ton bag to keep the barbecue dry in the winter (I refuse to pay a stupid price for the official cover on principle).

Sheet DPM would be really good for the job, but, given it's covered up in use, I can't see why they'd make it especially UV proof. So, apart from the aesthetics ("some folks prefer blue") I was wondering if there's any official difference between the blue and black versions.

I've tried cheap tarps in the past, but the handle on top of the barbecue wears a hole over time. I'm hoping if I use DPM underneath I can just replace it as needed under the bag.

TIA for any advice...

Thanks,

E.

Why not stick an overturned jam jar over your handle to stop any wear ?

It must be very inconvenient having to lift a one ton bag off each time you wanted to use the barbecue.

It's only water. I just drain it out with a syphon.

The Barbie lid has gone a funny shape now tho.
