Topic tags/keywords: question refurbishing finishing

Hi All,

A friend asked me if I can repair the top of his piano….

The problem is not the lacquer finish, its that its 20 years old, and half of the top (where it was folded over) is the origional dark stain, and the half that was exposed to sunlight streaming in the window for 20 years is far, far lighter. The origional is a very dark maroon stain, and the damaged part looks like light oak. He wants the repair to match the damaged color, not the origional (the rest of the piano has the lighter color from the UV damage)

If it were solid wood, I would just strip it down, sand it back to base, and refinish. The problem is that its veneer, so I’m afraid that I’ll sand through to the substrate.

Is it possible to lighten the origional stain to match the damaged part (or at least close)? Or am I getting in way over my head.

Might require new veneer.

Maybe the client would like white?

Asking for trouble, cover the old up and put the other in the sun, sounds funny but to match what mother nature did to the other side you have to do the same again. My experience is the veneer no matter if it is thicker than normal would not stand up to the sanding required and if it did, the stain would not penetrate and I have seen some that when it looked fine after sanding they stained it and hit the glue layer…... Glue seeps into the wood some and in spots more than others and with veneer your are already so close to it…..... Best to start over or do not do it at all….. Someone else here may have a better solution I am only going off from what I have learned. Some good and some bad but still a worthy ride…...

Tell him to turn the piano around and in twenty years it will match.

Have your say...
