OK, so as you can see from the majority of my projects I mainly work with pine and have a great Amber Shellac finishing method. I cut the can 50/50 with Denatured Alchahol before I apply. I have read over and over that cleaning with ammonia is just as effective as DA. So if thats the case, could I thin with ammonia? Ammonia is $1 for 64oz here. A LOT less expensive. If not, why? Just curious.
Thanks!

I really don’t know the answer. But I know I’d much rather smell alcohol than ammonia.

In a word, NO. Alkalines will actually destroy shellac, as opposed to simply thinning (or dissolving the solids). I clean my spray gun with ammonia, since it’s cheaper and actually removes the shellac….if I cleaned my brushes, I would also use ammonia. But stick to alcohol to dilute and dissolve the flakes.

I know nothing about shellac, but I do know that ammonia is going to, potentially, seriously change the colour of your wood. It’s “famous”, as it were, for the effect it has in darkening oak (to almost black in some cases), but I have personally found that it can re-colour pine significantly too.

Ammonia works great for cleaning shellac brushes but won’t work to dilute your shellac. (Don’t ask how I learned this!)

Tell someone “dont look down!” and what will they do? Look down. So I tried it just for grins. The ammonia I used turned my amber shellac (already thinned 50/50 with DA) purple. Sprayed a stick out of the scrap bin. I now have a koolaid purple scrap stick. lol. Enough experimenting. Off to spray some real shellac :)
