will 10mm PVC bevel in the sun?
Hi,
We are resurfacing a billboard with PVC (Forrex). I was going to use 10mm pvc, with the hope that it will not bevel in the heat. We would put expansion hole on to allow some expansion.
My fear is that it ends up looking like a corner shop cheap and nasty sign… come on we’ve all seen them.
What do you think?

….dont think you mean “bevel” do you 😕 How big is the billboard ? I would tend to say it’s probably a mistake, better to use dibond or equiv. but obviously cost would be an issue.

i recon nigel is right… pay the extra, get a better finish and sleep at night 😉

You will have some problems over such a large area as a billboard with 10mm
As the lads have said and my choice would be dibond
Its actually lighter and easier to use than 10mm and will last so much longer
I don’t think there’s a lot of difference in price eitherJohn

I agree with the others.
I have, however, used a material called Komacel before which is similar to foamex but a lot more stable. I think Amari sell it.

I may be being a total gimpoid here… nothing new there, but there are a range of very cheap ally-faced boards about that weigh in at the same price as 10mm Forrex. Cox have just started to supply Di-Lite at very reasonable prices and Europoint do LeBoard, again, great pricing. All I’m meaning is, is there any need to use the foamboard?

I’ve never used any of these composite sheets. How do they perform? What I mean is, do they stay absolutely flat in hot weather? Everything expands and contracts with temperature change, doesn’t it? I’m not suggesting that it is the case, but as I say, I’ve never used any.
Oh and yes, you are a gimpoid, either way. If you want to fight about it I’ll see you at the Europoint stand at 2. 😛

I’ve found them to be pretty good. I still drill the holes for the screws slightly larger than the screw thread, but I’m beginning to wonder whether its necessary. I fixed an 8×4 thats in direct sunlight virtually all day and I have seen any major bulges or problems. I know its not summertime proper yet, but even so, we’ve had some reasonably hot days.
One thing that does cause me problems, more from my skin flint nature at not wanting to invest another few grand in equipment, but when it comes to cutting the LeBoard in particular, I go through a huge amount of blades to get a clean cut. This could be down to inferior quality blades for the most part, but changing a blade 3 times for a 1.5 metre cut seems a tad excessive.
Thinking about it, whizzing it through the table saw would be the way to go. If I had a brain I’d be seriously dangerous! 🙄 😮
