Merry Christmas and Happy New Year.
I have two questions. I’ve been asked to refinish a kitchen table top that a few years ago I applied several coats of polyurethane to. Can I just sand it first to rough up the surface and put another coat of polyurethane on top? Or, should apply a coat of shellac first? or what?
My second question is, where can I buy a good quality natural bristle brushes?
Thank you for any and all suggestions and advice
