What paint to use for edging Dibond?

[Steve Morgan]

Simon, I think the core material of Dibond is polypropylene, which rather like polythene will resist most paints. You might find a that a vehicle primer paint will work, as in plastic bumpers, then gloss over that – Trickey job with a brush.

Core of any composite I have used has been black Simon, probably find the same for most of the UK members. I don’t think I have ever painted the edges but then I have never used anything above 3mm. Have oversized the print slightly on a couple of occasions & wrapped it round the edge to seal on the back but never painted. Used acrylic primer on foamex before now without problems.

6mm? i havent seen composite in 6mm though i have seen various makes of similar upto 10mm

to be honest mate, if the customer is fine with it i would leave as is, its often the signmaker in us that makes us so concious of things others simply over look.
dont get me wrong, its always a good thing to go that bit extra to get the job looking as you wish, but you could be taking on a long tedious task here.

as has been said, the core of the sandwich of layers may need primed then painted to prevent flaking. my thoughts are what you do to the side, may bleed onto the face as a result adding more work in cleaning up.

we only use 3mm… edges doesn’t really matter at that size.

the majority of dibonds we use have black inner.

[Simon Worrall]

Thanks for all your input. We have decided not to paint the edges, should have got black cored dibond.
Anyway here is a visual of how it is supposed to look, and also a pic of part of the logo cut in 6mm dibond. Its actually very good stuff, and very strong too. Pity about the core.

ive never seen it with as white a core as that. ive seen a sort of light grey core, black and dark grey. does the 6mm composite cost allot more than the 3mm?
and does the front/rear aluminium skin increase in thickness, or is it just the core?

i hear what you say about it being very strong mate, i am guessing you probably already are, but i would definitely put some form of support behind the sections protruding out the top of the building.

Simon sorry for questioning your knowledge but from the photo posted that sheet looks more like foamex than composite is it deffo a plastic aluminium sndwich panel? 😕

[John Harding]

oh and to answer your question I think it looks just fine with a white edge no need to paint black anyway IMHO 😀

[Martin Pearson]

So how long have you been doing the signage for computer games Simon :lol1: :lol1:

[Simon Worrall]

Robert, the SIM’S is getting 25mm square ally tubes behind it to hold it away from the surface, and to give it more strength, the BAKERY is getting 3mm aluminium flats.
I actually bought the material some years ago from a hypnotic sales lady for no particular reason other than I was hypnotised. 🙂
It was surprisingly inexpensive, had an excellent surface finish, and is very strong.
Anyway, finally I had a chance to use it.
Yes John it is a plastic-aluminium sandwich. I think the white edges spoil the shadow effect somewhat, but it is acceptable. The usual 4mm we use has a black core but is not strong enough for the sticky-uppy bit – we get wicked north west winds round here during the summer that blow for days. We are using 4mm for the BAKERY part though.

Martin it took me a while, but 🙂
