Ivoroid

Post by limehills » Thu Jun 27, 2019 12:57 pm

Alright so I've never really used plastic binding before, and I'm wondering how it behaves with a french polish finish, does the shellac stick to it ok? i just don't want it flaking off after a while.

I mostly use ABS plastic bindings from StewMac and I always seal my guitars with shellac prior to spraying lacquer. Never had any issues.

I'm finishing these two up right now in French Polish and it sticks just fine. I am using a dark amber button shellac so it does change the color considerably so that might be something to consider. I think it looks good but you may not. BUt otherwise Shellac sticks to everything well.

Also don't forget to wash coat the bindings first, especially if you are using rosewood back and sides. The rosewood will bleed color into the ivoroid.

Wash coat might not be the right terminology since that commonly is used to refer to the whole guitar, spit coat too. Sealing might be a better word. But anyway, in French Polish to protect certain parts of the work from wood color bleeding you seal it first. For bindings on a guitar take a small piece of cloth, say something like 10x10cm and fold it over and over till you have a small square. Drop or dip some shellac on it and rub it out along the bindings in long strokes. Turn the cloth over and or refold it often so as to have a fresh surface without any color bleed in it. The first coat might require a few of these cloths. 30 minutes should be long enough to do it again, I usually do 3 coats. Then I will use something like a Hake brush and brush a spit coat of shellac on the entire body but still trying to avoid the binding. After that you should be good to go, everything should be sealed and you can begin filling and or French Polishing.

I think the dark amber stuff looks great too. I always used a lighter amber shellac. This is the first time I am trying a dark button shellac and I really like it.
