I tried to purchase dewaxed shellac at Lowe’s and nowhere on the labels does it say whether it is dewaxed. How can I tell?
27 June 2017 at 9:47 am #313274Did you check if the manufacturer has a website with information?
I got waxy shellac flakes the other day, and mixed up a batch with alcohol. After a while, two layers separeted. I think that I read somewhere that one of the layer is the wax.
Industrial products might have supplements that prevent the separation though.The only thing I’ve ever seen at Lowes and Home Despot is Zinnser shellac in cans and in spray aerosol cans. From what I’ve read, the cans are waxed and the spray is not. I’ve had awful luck with the cans of premixed Zinnser shellac…soft, poor binding. It’s worth buying flakes and mixing it yourself. Put flakes in an appropriate container. Eyeball the height of the flakes. Put your thumb at an equal height above the flakes, so that the top of the layer of flakes is half way to your thumb. Pour in appropriate alcohol up to where your thumb is. Shake. For the first half hour or hour, shake it very frequently. After that, shake it when you walk past it. It won’t all dissolve at first. You’re mostly shaking to keep it from turning into a lump. It will be ready the next morning. You may need to thin it depending upon what you want to do.
See if you can find information about their Seal Coat product. That may be unwaxed shellac. But, I’d just get flakes and mix your own. You can mix just a few ounces (couple hundred mL) if you like.

27 June 2017 at 7:10 pm #313308Here is a formular for the metric system.
A one pound cut means one pound (453,6g ) of shellac for one gallon (3,785l ) of alcohol.
If you use the rule of proportion, that means that for a volume of “y”-liters, you need “x”-gramm shellac.x = y * 453,6g / 3,785l
For a small amount of mixed shellac, like 100ml = 0,1l, which is enough for small projects this results to:
x = 0,1l * 453,6g / 3,785l = 11,98g ~ 12g
If you want a two pound cut, multiply the formular with 2, for a four pound cut with 4.
Btw, if you only want to use a scale for measurement, 100ml alcohol weigh 78,9g.
I guess one gramm more or less, does not matter that much, if you want to do it quick and dirty.

With 128 US.fl.oz. to 1 US.liq.gallon and 16 oz to 1lb, this formular relates to1/8 oz shellac per 1 US.fl.oz. alcohol
for a one pound cut.
