Why I love shellaccomments (10) September 6th, 2013 in blogs
I hate finishing, but I hate it much less when I use shellac. Backhanded compliment, sure, but if you knew how much I hate finishing, you'd really be impressed!
OK, enough nonsense. Here are all the things I love about this centuries-old wonder finish. First, it smells great as you are using it, kind of old-timey, like oiled leather or fine wine. It goes on with a rag or a brush, depending on how much you've thinned it and how you are using it. It dries super-fast, completely cured and ready for sanding in two hours or so, meaning by the time I finish a number of parts and assemblies and take a coffee break. I'm ready to sand lightly and apply another coat.
Also, shellac can add tone, much more safely and predictably than stains and dyes in my experience. You can use the amber variety out of the can, for example, (but thinned a bit) to add warmth when your walnut looks too cool for its own good.
I also love that you can just let your brush dry hard, and just sit it in some shellac for 1/2 hour or so to resoften it the next time. That's because wet shellac dissolves hard shellac, even hundreds of years later, which is why coats bond to each other so beautifully.
Best of all, shellac just looks and feels fantastic. It is a very hard and crystalline finish, and the wood shines through gorgeously.
Not convinced yet? How about the fact that shellac is also the greatest sealer, going under almost any other finish to prevent blotching? Try a very thin coat, wiped onto on cherry before applying oil. Fantastic. Phenomenal. Unparalleled. Etc. Best of all, any other finish goes over the top of it, as long as you used the unwaxed variety of shellac. Out of the can, that measn you'll need to find SealCoat, not the normal amber and blonde stuff.
Some important tips. Whether you use shellac from the can or mix it yourself from flakes, use the unwaxed variety if you can and be sure of its freshness date. Waxy shellac is not as durable and water-resistant as unwaxed, and old shellac will never fully harden. Always thin shellac, down to a 1-1/2-lb. coat for brushing and thinner for wiping. And don't linger as you apply it. Put it down as evenly as possible and move on, otherwise you'll begin to drag the shellac as it gets gummy.
