Can you sand finish off veneer?
Can You Sand Veneer? As you might expect, veneered pieces are very delicate and require careful sanding to avoid irreversible damage. If you sand veneer too much, you may render it unusable.

Do you have to sand veneer to refinish it?
It is the ability to sand the surface that determines whether you can remove the existing finish.

Is it OK to apply polyurethane to wood veneer?

Unlike lacquer or alkyd varnish, polyurethane is a plastic, and that fact becomes obvious when you spread it too thick.
What’s the best way to repaint wood veneer?
