Parents
Love Shellac
Why this traditional finish may just be the best choice for your net
woodworking project..
If you do a quick search of the internet for articles on shellac
you will find hundreds, maybe even thousands of them discussing
different aspects of this historic product. You will undoubtedly find
articles discussing shellac's history and origins. Just in case you
don't know, shellac is a resin secreted by the Lac Beetle and
primarily harvested from India and other countries in south Asia.
Favored by furniture makers during the eighteenth and nineteenth
centuries, as well as antique furniture refinishers and period piece
makers today, it fell out of general favor after the development of
lacquers and hard wearing polyurethanes.
Modern woodworkers have created dozens of lists explaining why you
should or shouldn't use shellac. All of these lists are written by
people with years of experience and mounds of success with the various
products they support. Without having to recreate the Lincoln-Douglas
debates over the subject, it is clear that both sides are missing the
number one reason that sets shellac apart from other finishes
available today, parenthood.
Parenthood you say? I'll explain. So there you are in your shop.
Your new baby is inside your home starting to crawl and play (and
chew) on everything in sight and you have decided that your child will
have only the best and finest crafted wooden toys. All made by you;
parent, hero, and most importantly woodworker. As the first few toys
come rolling off the assembly table, you start thinking about the
paint thinner, latex gloves, and the various toxic components in oil
based polyurethanes, not to mention the mess that has been required
for every other project you've completed. That doesn't sound like
anything that you want your new pride and joy to cut that first
incisor on now does it? Shellac to the rescue.
That's right; parenthood and shellac go hand in hand. Why you ask?
The first and best reason is that shellac is non-toxic once cured. So
non-toxic in fact, that a shellac/wax mixture is used to coat apples
in supermarkets. It is also used as a coating for pills, candy, and
the inside of ice cream cones. Far more shellac is used by the food
and pharmaceutical industries than the woodworking industry. I still
wouldn't hand your child a bowl of shellac flakes and soy milk, but
it's nice to know that your teething toddler isn't getting a mouthful
of toxic chemicals.
So shellac is safe for the kids. That alone should be reason to use
it, but there are others. Children as most parents will tell you are
incredibly destructive. Who wants to refinish a toy that has a chipped
and cracked poly finish all over it? That is a lot of sanding and
headache to get a surface ready to be refinished. However with
shellac, a light scuff sanding and then a fresh coat will fix
everything. The new coat will melt right into the old, creating a
piece that looks like new. Plus it is incredible quick to dry. Thin
coats (recommended) will dry in minutes. If the finish is applied in
the morning, your little one could be playing with that favorite toy
before the day is out.
Here is a short list of a few more benefits:
- Incredibly clarity, even with the darker toned shellacs
- Wood looks more natural, feels better to the touch
- Can add color to the wood without the use of other stains
- If you are using pine, shellac will seal the knots and stop the
pitch from bleeding through
- Forgivable and repairable
- Contrary to popular belief, is actually quite tough and durable
- Versatile application methods - can be wiped, padded, brushed,
or sprayed
- Fun to mix up ( I like mixing up shellac - what of it)
Convinced that you should give shellac a try, but still scared of
those pesky flakes? Well its time to get over it. You stepped up to
the plate to become a parent didn't you? Using shellac is a lot
easier. Shellac flakes are easily and readily mixed with denatured
alcohol. Add flakes to the alcohol and let dissolve, gently shaking
occasionally. This can take between one and two days, so plan
accordingly. Two pounds of flakes poured into a gallon of alcohol
creates the well known "two pound cut". If you mixed four
pounds of flakes in with a gallon of alcohol you would have a
"four pound cut." Do the math on smaller mixtures to stay in
proportion. It doesn't get much simpler then that. The key to remember
though is that shellac does have a shelf life of only about a year, so
try to mix up just what you need for a project. If you do mix more, a
good rule of thumb is to date the mixture. For those of you who want a
little help the first time, Hock Finishes (yes the same people that
make those really amazing hand plane replacement blades) have created
an easy, all in one starter kit for the shellac newbie. It comes
complete with all the instructions you will need and enough flakes and
alcohol to create a small (10 fluid oz.) project sized batch of
finish. Once you get your shellac feet about you, you can upgrade to
buying bulk flakes (also available by Hock) and provide your own
alcohol. Try storing your mixes in sealed mason jars. Now get out
there and shellac a few toys for the kids.
