what sort of paints should i use for foam board?
We have a job to do for a customer, it is a facia board 4mtr x 0.6mtr and the design to fit in with what they have already is a grey to white fade.
I was going to get it digitally printed but with all the talk on the boards at the moment about spray painting I thought this might be a feasable alternative. What I would like to know is how easy it is to do a job like this. The fade runs from the top of the board to the bottom from quite a dark grey to almost white.
What sort of paints should I be using ?
Any help or advice would be much appriciated. -

martin one of my first jobs last summer was to do a sign for a local factory near me & i used foamex, i gave the foam to our local car body shop & when he saw it he decided to scoch it down first, then use plastic primer & 2pack auto paint, just as iof he were painting the plastic bumpers on a new car, i saw the sign last week & it still looks as good as the day i put it up, hope this helps a bit, eddie

Hi Martin, I have done this type of work in the past and ALWAYS use PVC inks. The best way forward is to mix various shades of the greys in seperate containers ( I use cleaned baked bean cans ), mix the darkest first, then lighten it slightly with some white for your second shade, then add some more white to that for your third shade, etc ,until you have say, five shades from the darkest grey to the lightest grey. The definition should be such that you can see each shade and they do not look the same colour. Clean the foamex first with solvent,then lay it down onto a trestle table and spray the ink onto the foamex in a light coat, rinse out the spray gun and reload with the second shade and away you go, remember to wear a MASK and have GOOD VENTILATION. Because the foamex is off the ground on a trestle table, any dust that might blow at floor level will pass under the work.You can spray the work wet on wet and leave it to dry overnight- job done !!

Thanks for the advice so far people any more hints, tricks, tips etc will always be appriciated.
Eddie, was it expensive to get the local body shop to spray it ?
Brian, do you start with the lightest shade first and then work to dark or the other way round? I take it you need quite a fine nozzle on the spray gun. -
the way i would do it is as eddie said ,we would plastic prime panel after giving to a good key with 500 then mix a Flexible additive in with the paint the only thing i would say to you is if you have to go out and buy all the things above it way work out cheaper to get it digitally printed and the fade would look better i think

We tried to spray a large batch of foamex for a client and tried lots of different methods. We took them to a car spray shop and it started to peal off alomost immediately.
We have tried Quad paints and two part, but now found a supplier that produces an acrlic paint that goes straight on and stays on. It comes in tins or aerosols.
Call Spraylat International on 01536 408409. It is not cheap but it is great stuff. Ask for Series 10 spray
I do not know about graduating it but you can put it in your spray gun
Hope it helps
