1 – Q: Shellac is an old-fashioned, outdated finish.

A: No, Shellac is all natural, organic, child safe.
Shellac has more modern features and ‘green’ benefits than any other wood finish in the world.

2 – Q: Shellac turns ugly and dark as it ages.

A: Shellac is naturally UV-resistant and does not yellow or darken with age.
The dark shellac seen in older homes is a less-refined version
that was naturally dark, or was tinted by finishers when dark wood colors were popular in the early 20th century.

3 – Q: Is shellac made from bugs or bug droppings?

A: No, Shellac is a resin secreted from the tree sap by the lac insect to form a cocoon, much like a silk worm.
It takes about 100,000 lac bugs to make 1 lb. of shellac resin.

4 – Q: Does a shellac finish turn white when water touches it?

A: A properly applied shellac finish is remarkably water-resistant and, in most cases, will stay clear after hours of exposure to water, making it a great finish for most interior surfaces, including woodwork, trim, doors, cabinets, paneling, furniture, and for floors, Button Shellac (yes, floors!)

5 – Q: Is Shellac brittle or easily scratched?

A: Shellac is a tough, durable finish that is less brittle than lacquer and is not easily scratched.
The process of making Button shellac yields a tougher resin. Unlike polyurethanes, a damaged shellac finish can be easily touched up or renewed by brushing on another thin coat.

6 – Q: Is Shellac compatible with other finishes?

A: Shellac will adhere tenaciously when applied over almost any other type of clean, wax free, and oil free finish.
(To assure a clean surface, especially on older grimy surfaces, use a wood cleaner like H. Behlen’s De-Waxer 741, to avoid possible stains or damage from water based cleaners.)

To seal wood before applying polyurethane or
other finishes, Bulls Eye® SealCoat™ is a shellac-based universal sanding sealer that is 100% wax-free.

For refurbishing a worn finish, a SealCoat makes an excellent transitional coating or bonding coat between an unknown coating and a new topcoat.
NOTE: (Regular shellac may not be compatible as a sealer under certain polyurethanes, as they contain small amounts of natural wax.)

7 – Q: Can I make a Shellac SealCoat?

A: Yes a ‘SealCoat’ is a DEWAXED Shellac Resin dissolved in
Behlen Behkol or a 190 Proof Denatured Alcohol.
With a wide color variety of Dewaxed Shellac Flakes, you can make your own universal sanding sealer in a range of light to deep tones to match your project.

“Not all Denatured Alcohols are equal”

USE a GOOD Shellac Solvent for making your own shellac ‘Seal Coat’ finish.
A ‘denaturant’ is added to Ethanol Alcohol (a drinkable spirit) to make it unfit for consumption.
The original denaturant was Methanol Alcohol.
The term ‘methylated spirit’ is still sometimes used referring to Denatured Alcohol. ——–

Unfortunately NOT all Denatured Alcohols are equal and there is no purity standard for ethanol content to be labeled  “Denatured Alcohol”. High test, 190 proof (5% denaturents), Denatured Alcohol is preferred as a Shellac flake solvent.

It is next to impossible to find a 190 proof alcohol at the ‘big box’ home improvement or hardware stores. Many brands have as little as 50-60% Ethanol – and the balance cheaper alcohols and denaturing solvents.
Recently I went
in search of high test Denatured. Out of ten paint, hardware and home improvement stores – only the local Sherwin Williams paint store had 190 Proof. The Material Safety Data Sheet will list the ingredient percentages of the product (most cans do not).

A 190 Proof Denatured Alcohol is operator and earth, ‘Green’, friendly.
“Klean-Strip Green” is one retail brand of ‘190’ Proof Denatured Alcohol.
If you find a 190 proof Denatured Alcohol, buy locally and save on shipping.

We ship Alcohol in quarts to avoid costly flammable shipping charges.

Available from Shellac.net
•• Select 190 proof Denatured Alcohol Shellac Flake Solvent
– excellent for padding and french polishing.
or
•• ‘Behkol Alcohol’ (Denatured Alcohol) is formulated by BEHLEN specifically to dissolve shellac flakes and dilute or ‘cut’ liquid Shellacs.  Behkol will make a shellac that has a little more open and working time.

Shop Note: By using a known Denatured Alcohol proof or purity and settling on a brand you will have more predictable results by eliminating one finishing variable.

We adjust for weather and heat conditions by adding SHELLAC Retarder (not lacquer retarder).
When the shellac is drying too fast due to heat, low humidity, or excessive airflow, add just enough retarder to enable easy application.
When spraying, shellac retarder will help eliminate over-spray and orange-peel.
Avoid over-use of the retarder.  Keep in mind that use of the retarder will require longer drying times between coats of shellac.

NEW CROP – Bysakhi Button Shellac

Bysakhi Button Shellac
Now Shipping


Varieties of shellac resin differ primarily in color as well as properties.
The type of tree, climate conditions, the region where harvested, and the time of year harvested all play a role
in determining the different colors and shellac varieties.

Handmade Button Shellac is produced by placing Seedlac into a long narrow cloth bag and heating with a charcoal fire.
One end of the bag is attached to a windless and is gradually twisted.
The heat from the charcoal fire melts the seedlac which is forced through the cloth by pressure.
The molten lac is scraped off and placed onto metal sheets and left to dry.
The making of Lac buttons requires considerable manual skill and long experience.
