Mix ratio for sanding sealer?
I tried to make a solution with 1 part resin to 2 parts alcohol, but it got very thick like a gelatinous mass. Do I need more alcohol in this solution or do I need to heat it up in order to get it more liquid?

Sanding/Sealer as in 100% wax free shellac? Like Bullseye Sanding/Sealer?
Not understanding the "resin" part:(

Re: Mix ratio for sanding sealer?
It sounds to me like the alcohol is incompatible with the resin. Alcohol works with shellac if it is high percentage. Read the label, your finish may require a proprietary reducer.

Re: Mix ratio for sanding sealer?
probably need a bit more detail, lots of different types of resin available, I can't think of one that I would mix with alcohol though Come to think of it there are also a lot of different types of alcohol available, some almost pure & some with lots of additives.
What is it you are trying to achieve/are you looking to do, I have different types of sanding sealer for different types of work & also dofferent finish coats again dependant on the job or type of finish I want

Re: Mix ratio for sanding sealer?
I used wax free shellac and methylated spirit. I need to use it for surface stabilizing before carving in order to avoid breakage at the top of the cuts. I have had the shellac for many years. Can it be out of date?

Re: Mix ratio for sanding sealer?
Shellac can definately be out of date.
The solvent for shellac is DNA or DeNatured Alcohol
Generally a sealer is a one pound cut. That means one pound of dry shellac flakes to one gallon of DNA. --- that is pretty thin - almost like water.
A three pound cut (3 pounds of flakes to one gallon of DNA) is a finishing cut.
The stuff in the can is already a mix so you would need to know the cut to figure out the 1 pound cut for a sanding sealer. OR you can just buy a can of sanding sealer

Re: Mix ratio for sanding sealer?
Here is a google translate from a norwegian site that describe the alcohol:
-------------------------------------------
Red liquor is 70-95% denatured ethyl alcohol, ethanol. The red liquor is added to a denaturant which makes it useless for food and drink, and often the dye fuksin which gives a reddish color.
-------------------------------------------
So one pound to one gallon is ratio 1 to 8. Then my solution is wrong and I need to mix in more alcohol.

Re: Mix ratio for sanding sealer?
Usually it's not recommended to thin resin, but I know for cleaning you use acetone. You might try that instead of alcohol.

Dry shellac flakes have a shelf life of about 3 years.
Once dissolved in alcohol, the shelf life is about 6 months.

You might want to check what else is in the stuff you have before mixing more injaru-eri wrote:Here is a google translate from a norwegian site that describe the alcohol:

It may contain other additives which give problems with mixing with shellac
