Many thanks to Jon and Bill for the replies. I'll check out both adhesives. Bill, thanks for the detailed procedure and link!

I don’t care for their procedure either. There is one water-dispersed contact adhesive that works really well. 3M Fastbond Contact adhesive 30-NF It comes in green and white, naturally you’ll want the white. I do a lot of Vagias Keytops as well as Pianotek’s German tops and have never had a failed glue joint with this stuff. I think it’s as strong as solvent based CA, with all the benefits of a water based product, i.e. easy clean up, no odor, etc. Here’s my procedure: 1. Surface keys 2. lay out tops upside down 3. apply glue to key then Keytops then a second coat to the keys (I use a 1” foam brush) 4. let dry, a fan helps if it’s humid, but generally like most water based products it dries within half an hour. 5. Assemble and apply clamping pressure to set the bond. I have a quick release vise with large wooden jaws (cork lined) and do 2 keys at a time which goes quickly. Here’s the technical stuff: http://multimedia.3m.com/mws/mediawebserver?mwsId=66666UuZjcFSLXTtnxft48s6EVuQEcuZgVs6EVs6E666666-- Bill Costanzo www.rochesterpianotuner.com ________________________________ -------------- next part -------------- An HTML attachment was scrubbed...
