I see furniture in upscale stores that have back-painted colored glass over MDF. How is this done without common glues that will not eat through the paint, leaving spots? I've had some experience with back-painted glass with doors and table coverings. With regard to the latter, we've set the glass using double-faced tape that has no show-through, although it raises the surface 2mm.
I've a project now where I need to face a vertical structure with back-painted glass in a RAL color using back panels of MDF. My largest panels are 2'x8'. I need a clean surface. I can't attach the glass with screws.
The back-painted glass I've been using is from a local source that requires the glass to be tempered so that it can adequately absorb the paint while in the oven. This method, which is the best quality, cannot be glued without the glue showing, hence using double-sided tape, 2-3mm thick.
There are of course suppliers that sell paint for back-painted glass, but ultimately you don't have the quality of paint that has been applied and passed through an oven. How can you apply a back-painted glass over a surface with a type of adhesive that will not show through?

From contributor D:
I think you are on the right track with the double sided tape. I worked for an office furniture manufacturer that had a lot of glass spec'd on vertical panels. We used the 3M VHB type tapes with no failures in the field. We did, however, have some failures internally. Once you set one end of the glass in, there was no moving to be done. We snapped several pieces of glass in half trying to reset them.
Can one use a non-acidic, neutral cure silicone on glass that has been back-painted with NC lacquer? I'll do a sample… interesting.
I'm aware of Glasspaint, but it's very expensive. I'll talk to them regarding adhesive techniques.
Although the client would probably go along with whatever I offered, I don't want to over-tech, and if this can be done without using ceramic back-painted tempered glass, safely, with a guarantee of adhesive not showing through, then this is the direction I prefer to go.
