<HTML><HTML>Greetings,              I h= ad this problem with a brand new set of keytops that I replaced on an old gr= and piano at a church. I used PVC-E (Elmer's glue). It turned out that when = I took 150 grit sandpaper to the underside of the new smooth plasic keytop a= nd roughed it up a bit the glue worked fine.

I service on old upright piano for which a previous technician installed <BR= > new plastic keytops, probably a couple decades ago.  They keep coming <= BR> off; nearly every one has come off at least once.  I used to use Dryburgh superglue, but they began coming off again, so I switched to Weldwood contact cement, and that nearly always does okay for me, but not on this piano.  This has been a chronic problem for years. Do you have a never-fail suggestion for some other glue?  I'll be seein= g this piano again the end of next week.  Preferably something that sets = up soon enough so I can do the repair, then tune the piano, or the other <BR= > way around, and that's locally available.  I like to stay away from <BR= > glues so dark that they show through the plastic. It's been a while since I've been on this list.  I'm doing well and hop= e you are the same.  I'm swamped with piano work, like probably everyone = else this time of year.
