You should be able to thin up to 30% (using mineral spirits)...but that's
it. Still, I'd try it, test it, let it dry and see how it does. Good luck Rob -- http://www.robswoodworking.com wrote in message ...

I don't know if Minwax makes water base, but... How do you thin Minwax Polyurethane? Thanks 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.

Most of the solids are already in a lump in the bottom of the can, until you stir them in carefully, without introducing air into the mix. Stir completely, for about 4 minutes, before starting to thin. And don't try to work with material that's too cold, either. Check the label, and maybe store the cans inside? Patriarch |

The next day I got congeal mixture, below the harden top layer! There are not instruction of thinning, but cleaning with either minerals spirit or paint thinner. The instruction printed on the can "Do Not Shake" in bold letter, "Stir slowly......" why? So as to not induce air bubbles in the poly. Shaking will produce small air bubbles that will mess up your finish. Thunder |

Thanks 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 SH |

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.

Once it has reacted it can not be redissolved. -- Jack Novak Buffalo, NY - USA (Remove "SPAM" from email address to reply) |

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. dwhite |

This is the stuff that evaporates and may pollute the air. |
I am assuming you have oil based polyurethane and not Minwax's water
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. "Geroge Barns" wrote in message ...

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. SH |
Missed the start of this thread...
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. John |

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. |
