We haven't done this project ourselves (yet), but it's something we're considering for our own kitchen. So, we set out to find DIY backpainted glass on the web. Let's just say it's not very widely represented. So, while we aren't going to venture to tell you how to do this (yet!), we would like to share with you what little we turned up...

Maybe Im missing something?? Instead of painting the glass.....Why not paint the wall and install the glass over that?
You would see the adhesive if you did it that way
I read in another post about doing this with Plexiglas. You could paint the wall whatever color you want and place the Plexiglas over it.
Then you could screw the Plexiglas in place around the edges and use some trim to cover the screws.
I have wanted to do this for a while.
