With a very fast drying time shellac sealer is the natural way to seal your wood prior to applying the final finish (polish). It can be applied with a soft brush or mop. Work quickly because it will dry as you work. If more than one coat is required rub down lightly with 0000 steel wool and clean off the dust thoroughly between coats. Sealing the wood with several thin coats before polishing will fill fine grain and give you a silky smooth and longer lasting finish.
