I have come to many pianos where contact cement had been used and keytops were both discolored and coming off. Don't use contact cement. Years ago here on pianotech, no less a personage than Steve Brady suggested Duco cement for the occasional reinstallation of real ivory. Duco cement is not contact cement so the keytop can be carefully positioned. Duco cement is colorless and seems to be a good choice if the original linen is still present. If the keytop is installed without linen, the color of the wood could show through; I believe Schaff still has linen/glue wafers available. Kent Swafford
