The Corian is dark stone look and I want white letters. I dont want the whole sign a different colour otherwise I would have used material of the required colour. It is only the engraved letters that I want to paint.
Thanks, that is exactly what I’m after but I wonder if acrylic paint will withstand being exposed to weather conditions. Do you think I could I use clear coat over the top of everything?
You could use Corian glue/adhesive. This is used for joining two pieces of corian with a basically invisible join after sanding, and as such is available in any colour that Corian is.
It isn’t particularly easy to get hold of (at least for me in the UK) especially in smaller quantities, but I’ve had some luck on eBay.
This bonds very well to the Corian (as you would expect), and can be sanded
After I carved the Santa and text, I just dabbed the paint into the cut areas…I was not very careful…after the paint dried I took some 400 grit sandpaper and removed the excess. The paint on the surface came off after a second or two of sanding.
