Topic tags/keywords: question

I use the gallon size cans of poly and was wondering…..say I mix up a quart or so of poly and maybe 20% spirits, and I have a little bit left over…....what are the drawbacks of pouring that little bit back into the gallon container of 100% poly?

Good question. I’m varnishing my own cherry cabinets right now and always end up with a 1/4 cup in the sprayer.

If you’re using a paint filter and a viscosity checker thingy and, considering the paint thinner is constantly evaporating, I would think it shouldn’t matter unless it’s somehow poluted. Plus, I like to pour a little thinner on top of the can before storing to keep it from drying out.

Is 20% the right amount? sounds like a lot of thinner.

I was thinking it would be nice to thin the whole gallon but I would have to empty 20% of it and find a decent container. Just what I need – two cans to keep clean

Obviously, I’m a woodworker, not a pro finisher.

Good luck with your project.

I’d not pour it back into the can; I’d pour it in its own container.
Then the next time you mix another batch of the 20% thinned poly, mix in the other batch from before.

The main reason not to add the mixed stuff back into the unmixed can is for consistency.

Thanks Nightwalker, good idea…....that will give me a use for all those old spaghetti jars that I have been saving.
