After the shellac coat and the touch-up process, we did the next and last step ending up with my favorite finish for natural woodwork. It’s simply a very thin coat of varnish applied over the shellac with a cotton rag ‘pad’ that I make. Here are some of the perks using this process: There is minimal build up giving the wood an oil like finish, yet the varnish is more protective. It’s silky smooth. And finally – to appease my dutch sensibilities (read: frugal), it goes a loooooong way; I finished the entire interior with one gallon! 13 doors, 18 window frames, 32 window sashes, all the baseboard and casing in seven rooms!! To boot, the Window sills and the sashes were brushed on to give a little extra protection.
