If the cabinets are stained and sealed, then the only way to apply ANY chemical product is to completely sand them down and then apply the product. Timbor is not a great product for kitchen cabinets. It will leave a powdery residue. The best product is BoraCare, but the wood has to be bare. The basic method is to sand, treat with BoraCare and then refinish. Hope this helps.
