Instructions for Installing Keytops, Gluing and Trimming



Piano Keyboard Material & Accessories



After you have prepared all the keysticks and have removed the old glue and the tops are smooth and clean, make sure the surface is free of glue and dust. Avoid the temptation to leave the old glue on and apply the new one, this looks unprofessional.


You can use our Piano PVC-E Glue, using a thin bit of glue along the front of the keytop spread with your finger or use a Piano Glue Brushes 



Make sure when installing the keytops the standard position to hand is 1/16” past the front of the surface of the key front.


Once that is done place the keytop down against it and push down lightly to let it set. Remove any excess glue from the sides, wipe it all down with a damp cloth, wipe off excess glue right away, if you don’t do it right away it’s harder to get it off later, Piano PVC-E Glue works quickly, best if you leave it overnight to set.

Occasionally you will get an overlap, hangover on the insert. You want to have the overhang on the inside of the notch where the sharp goes.


Using a sharpened awl, scribe down each key being careful to file the entire length and finish the side with a fine file.



With both sides of the keytop filed, put the key in the vise vertically to cut out the excess material around the notch for the sharp.

Be extremely careful not to exert any side pressure on the file to finish cutting the notch.

Always have the keytop placed with the key cover facing you to prevent chipping, make sure not to scratch the key top.
