Do I need to back this type of sign?

Basic question I know.

I've done a couple of signs - cut in mirror image and put directly onto clear acrylic perspex then topped with vinyl. Before mounting do I also need to put something firmer on the back?

Thanks

horses for courses Sharon - it may help if we knew the size of the sign, the thickness of the acrylic and a slightly more specific description of the make up...plus, where's it to be placed - how high up and onto what?, brick?, fencing etc.

more soon

Mike has just about said it all Sharron, when you go to see a customer about any kind of sign these are the sort of things you have to take into account before you decide what sort of substrate to use.
As Mike says give us a little more detail about the signs you have produced and someone should be able to give you an answer.
Have you put the lettering on the back for any particular reason ? Maybe its because they are low enough for little fingers to pick off the vinyl, maybe for a completly different reason.

Hi Mike, Martin,

The sign was done on 4mm Crystalite acrylic, A3 in size. These will be mounted on an outside rendered wall as warning notices. The reason for reverse mounting was the prevent the little darlings from picking the letters off. With some of the kids in the village they don't need to be mounted low for them to have a go at them.

Sharon, you dont have to mount these on any other form of substrate if you dont want to, but if the building is rendered and you overtighten the screws when you nail it on the wall you will crack the acrylic, its very easily done as there is so much undulation in a rendered building.
I have just done some for a community centre, 10mm foamex with a PETG facing to help keep the vandals at bay!!! I would have used Aluminium panels but the building has quite a high limestone content and Ally goes a bit funny with time.

Thanks Martin,

That was what I wondered, to be doubly sure I'll see what we have hidden in the depths of the garage. Don't worry I've only had to pay for the cost of the vinyl. So there's still plenty of profit to play around with.

Piece of plywood or something similar would be ideal Sharon, just something to stop the jaggy bits (technical term) cracking the acrylic.
