I have a chess board I made with a high gloss rubbed out lacquer finish, using several layers of lacquer. What I didn’t see at the time were a couple small spots where I sanded thru to the wood. I noticed them when I was done but decided I’d go back and fix them later, and put it aside. Now it’s been six months, and I’m wondering if I can just go back and put some layers of lacquer over those spots (i.e. does lacquer still bond with lacquer if it’s been thoroughly cured?) and rub those out, or do I need to sand the whole thing off and start over?

Doesnt matter how long its been, lacquer will still burn in to itself. Yes you are safe to do touch ups.

+1 Just be sure to clean any old wax from surface.

If you used NC lacquer, then you can spray over it, although I’d wipe it with naphtha first and hit it lightly with some 320 or 400 grit sandpaper, just to make sure you have a clean, smooth surface.

However, if it’s catalyzed lacquer, then the sanding is mandatory since it will not amalgamate after a period of time.

Doesn’t this depend on the product? Most have a mil limit. I know mine does. How many coats?

Have your say...
