Im having some probs matching some new wood repairs to existing old furniture, and i think transtint & alcohol would work (minimal grain raising) from what ive read. Ive used transtint in shellac as toners but never alcohol.

Im testing on small scraps and would like to make up really small transtint alcohol batches. Around how much alcohol would I use for a single drop of transtint?

Im using klean strip slx denatured alcohol, should I use klean strip green alc instead? I just read the slx is half ethyl alcohol and half methyl alcohol, but the klean strip green is all ethyl. No idea if it matters.

Since a shellac solution is primarily alcohol, your transtint concentration with pure alcohol will be very similar. If you are uncertain about it, start with a dilute mix, maybe 25% of what you would normally use. Test it, and up the concentration as necessary. Or live with the more dilute mix and apply several coats as necessary to build up to the desired result.

Don’t the transtint bottles have recommended dilution on the label?

Regarding the choice of alcohol – it doesn’t matter all that much. Methanol evaporates faster than ethanol, so the pure ethanol product will dry a bit slower than the 50/50 mix.

Oh yeah, shellac would be about the same as alcohol wouldnt it. Sorry, didnt think of the obvious.Theres mixing suggestions on the bottle but its using the entire 2oz bottle into 1/2 gallon and i just wanted a much smaller test batch. Since its going to be close to shellac i know were to start.

Good to know about methanol vs ethanol drying time, thanks :)

There are 64 fl oz in a half gal. Keep cutting in half until you get to the amount you want then you’ll have your ratio.

I’ve always had to “sneak up” on the desired color when using TransTint. Test boards and some patience will give ya what ya want. ‘Sides that, TransTint is expensive, so a bad batch/mix gets pretty pricy. Once ya get the correct ratio, you’re good to go.
