I just stumbled across your video and to say thank you for teaching me something new. I am a wood turner and been thinking about using a sanding sealer but don’t know much about them. This put it into some perspective for me.
I almost always use 2lb cut, although I rarely use stain anymore. I’ll occasionally mix up 1/2lb or even a little less to use as a “flash coat” for finish repairs but the 2lb seems to suit
I noticed it didn't darken the wood to much. I like that. Great info! Thanks. I wonder if you could use turpentine instead of alcohol? And can you apply this over wood that has already had a cured volatile oil applied?
No you can't use turpentine instead of alcohol as the shellac is only soluble in alcohol. There may however be some finish mixes that incorporate a small amount of turpentine (which slows the drying time) but i have no experience with that. You can 100% apply shellac over the top of a curing oil (linseed, tung, hemp etc.) as long as the oil is completely dried and cured first.
You can use ordinary lacquer, such as Watco brand, as a sanding sealer too. And if you mix it half and half with lacquer thinner it makes an all-purpose solution widely used in Asia. You can use it as a primer or pre-stain conditioner, but also as a topcoat too., or just for touch-ups. You can apply it either by brush or cotton rag or spray gun. And you can apply as many coats as you like, allowing dry time in-between and lightly sanding as desired. Watch the "Royal Wood Polish Work" guy in Asia for more info, although he does NOT speak English. CAUTION: Use lacquer and lacquer thinner only in a well-ventilated area or wear a respirator!
It is referring to 2 pounds for shellac flakes diluted in 1 gallon of alcohol. It was the traditional terminology used to determine how to mix shellac.
Denatured alcohol and methylated spirits are the same thing, afaik. The denaturant, or poison that they add used to be methanol, that’s why they call it ‘methylated’. But a lot of alcoholics went blind or died from it. These days, I believe it’s pyridine. Maybe there are different denaturants that small better.
Methylated spirits has between 1 - 5% water depending on suppliers. Denatured alcohol is 100% alcohol with no added water. At least everywhere ive found it. Methylated spirits also smells worse, but in its treatment is made less flammable, meaning it flashes off slower resulting in a slower drying shellac.

My pleasure, glad this video was able to help you
2LB has always been my choice, both as a sealer and for French Polishing.
Thanks for sharing

Thanks for this information, much appreciated.
Thanks for this I have been thinking about giving shellac a try. The cost has put me off. Where do you get yours?
I got shellac from restorerschoice.com.au/ . But i always try to look around for the cheapest whenever i get it. Hope this helps.
@@AussieWoodshed Thanks for that. Its cheaper than the usual suspects. Bonus I can save on shipping next time I visit the M in L.
Would Turpentine as a solvent work?
Turpentine won't work for shellac as its not alcohol. Alcohol is required for shellac, commonly used is methylated spirits or denatured alcohol.
Hi what does 2ilb cut mean?

Thanks, so do it for most applications
