it.
Still, I'd try it, test it, let it dry and see how it does.
Good luck

Did you get a can of water based poly? That is what the reaction
sounds like. I don't know if Minwax makes water base, but...

Mineral spirits should be the preferred option. I can't recall how
much you can thin it. The ratio is probably listed on the can. That
being said, I've thinned poly by 50% or more to get a mixture that
will soak deep into the wood. It works very well for hardening pine
desktops.

The can says not to thin it though.

So as to not induce air bubbles in the poly. Shaking will produce
small air bubbles that will mess up your finish.

What used to be my favorite mix (until I started using Waterlox) 1/3 minwax
poly, 1/3 mineral spirits, 1/3 watco oil. If you are just going to thin to
a wipeable consistancy, only go about 30% on the mineral spirits.
Otherwise, you will need to use alot of coats to build up the material. Or
get smart and use Waterlox like I do <g>

May just be too old to be worth messing with. I incurred my
Father-In-Law's wrath when I cleaned out the old paints and stuff from
his shop. Some of those cans (half full) were more than 50 years old!
I actually had to send some of it off to the hazardous waste facility
because it was lead based.
Basically, if it is older than a year or so just chuck it and buy new.

Polyurethane is a reactive finish. It cures by reacting with the oxygen in the
air. Once it has reacted it can not be redissolved.

It is a tung oil based finish.
You can buy online at www.waterlox.com or www.amazon.com carries it too I
believe. I bought my last quart at Woodcraft.

What is it you like about Waterlox? I've heard good things about it,
but would value your opinion.
Dan White: I've read that finish manufacturers have reduced VOCs as
ordered by the feds, and in order to comply, must label the can not to
thin, since that would raise the VOCs and therefore, supposedly, air
pollution.

Thanks, Gary. I have to get started on my own poly project. I'm starting
with the oil based Minwax though. I've got hard maple butcher block and am
going to try some linseed oil at first, followed by maybe 3 coats of thinned
gloss poly, finishing with a coat of maybe slightly thinned satin poly.

Yes.

I use their Helmsman Spar Urethane and have had good results with it.

Volitile Organic Compounds. This is the stuff that evaporates and may
pollute the air.

based Polycrylic. You would have been alright if you simply removed the
thin film you found on the top of the liquid. The remaining solution is
acceptable but you should probably strain it.
The film that you found will not dissolve in mineral spirits. Once
polyurethane has cured, it will not redissolve in mineral spirits.
You can thin oil based polyurethane as much as you like. Thin it 20%
and it helps to eliminate bubbles and it gives the wet film more of a chance
to level. Thin it 50% and you have a wiping polyurethane. Thin it more and
it will start to look like an oil finish in that you will have a hard time
seeing a film.
You can shake the can as much as you like. As stated above, thin the
poly about 20% and tip off the surface of the wet film after you are done
brushing.
Good Luck.

It basically goes on like my home brew but is better. And I like the fact I
don't have to mess around mixing it. Another plus is the shelf life is
better than my home brew. It is very easy to use and rubs out excellent.
It is just a great product imho. Buy a quart and try it. You won't be
dissapointed. It comes in Gloss, Original (sheen is equivalant to
Semigloss), and Satin.

Why not just use Minwax wiping polyurethane? You don't get the quick (thick)
build that you get with the regular Minwax poly--which may or may not be an
advantage--and it does wipe on nicely.

I was wondering the same thing as I read throught these. Is he thinning to
restore older product, wanting to spray or what? We have a lot of answers
but I don't fully understand the question.
