His everyone, i have been asked to supply a few small signs for a building that faces the sea. The customer wants some sort of guarantee of longevity. I cant find any info about Dibond lifespan in salty conditions. My initial idea was to flood coat the panels wrapping vinyl around the back so covering the exposed edges. Should that make it last a bit longer? Thanks in advance for any advice.
I’d tell them you understand the problem, so what your going to do is wrap the vinyl round the back so that any shrink caused by salt won’t be noticeable and not something you wouldnt normally do. That your using a polymeric vinyl at 5-7 years or whatever and panel should outlast that in normal conditions. You can’t change the sea.
I think if someone explained to me things like this and then if someone came along with a cheaper quote and promising the world I’d be raising my eyebrows.. but then maybe that’s cause of what happens in our industry.
I don’t believe any ACM manufacturer gives long term warranties / guarantees , rather just guidance on life expectancy – totally different. Coastal locations will accelerate weathering, salt air etc. And covering with edge wrapped vinyl will make it look good for longer – a decent self coloured vinyl finish will outlast a self coloured ACM, definitely a good idea. Ask your supplier to give you a data sheet / statement on life expectancy and pass that on to the customer and give them your own warranty of 12 months only,
I wholeheartedly agree with you, for the first 15 years of sign making i cut and powder coated aluminium sheet and its definitely more durable. However, i suspect that the price of 12swg aluminium would price the job out – someone would quote for hoarding and win the job anyway. I suppose i just care too much lol
