Minwax fast drying polyurethane dries to white haze
Purchased last fall, opened yesterday. Stirred as usual, looked ok.
Applied with foam brush on test piece of medium pored teak-like wood. Set aside at room temperature and it immediately starts to look like I coated the wood in white soap. What the hey. After a couple hours no change. Almost looks like I painted the wood with white lead. I've used this produce before without problems, but it "might" be some kind of reaction with the wood. The wood was purchased at a farm sale in a batch of other hard woods that could have been over 30 years old. Some mahogany and what I thought was teak but I can't imagine what the heck happened. Maybe return the can to the store and try another batch. |

This sound like blush for sure which is moisture captured in the
finish before it has a chance to evaporate. I've only seen it with lacquer but maybe this "fast dry" is acting like lacquer and skinning over very fast, not allowing the moisture to evaoprate. With lacquer we add a retarder to slow the skinning to allow the moisture to escape. Typically only seen when you have high humidity. A few possibilities a - Moisture in material. I guess unlikely if this was the first time it was ever opened. - Shelf life problem and something went bad in the can. - High moisture content in the wood. I am not familiar with this product. Is it water based? If it is oil based, maybe try thinning it with some mineral spirits to maybe increase the open time to let the moisture escape. If water based, is there a thinner you can use, maybe flowtrol or something? Also, is this semi-gloss or satin? Those sheen killers are just white paint pigment so maybe somehow it got out of balance and you got all of it in one coat. On Feb 13, 10:00*am, "bw" wrote: Purchased last fall, opened yesterday.

Now that I think about it, while I stirred the can to mix the bottom layer for a while I looked at the lid and noticed it had the white soapy color, so then I touched the white with the foam brush first to see what it would do. Some of the white was already soaked in the brush when I dipped it in the main can. I ended up sanding the white off and trying something else. Now I'll take more time mixing, I didn't know that the sheen killers were white pigment. |

P D Q ----------------------------------------------- Doubt it, it's been very dry around here this winter. Wood stored on high rack in garage. Test piece was sanded as usual along the grain. Wood does "feel" moist or greasy to touch. It might be that I'm not that experienced with tropical wood. Tested another piece with mineral oil and it really looks good so I'll skip the poly. |

My first coat went fine but it "fogged" white during the second coat. Even though it was temperate and dry inside, the temperature and humidity outside was high and apparently some of the moisture seeped into the poly. I ended up dipping the desktops to remove the poly and recoating a week later and they came out fine. `Casper |

I ended up sanding the white off and trying something else. Now I'll take more time mixing, I didn't know that the sheen killers were white pigment.. Actually, the shine killers that break the reflectivity are usually some type of silica, flat ground to the manufacturer's specs. These will easily collect on the bottom of the can if the material is old, or in my experience, been exposed to a lot of different temp changes. (For example, here we have had some days lately where the overnight temp was 35 - 40 degrees different from the day temps). Do yourself a favor. Go to the hardware store and buy yourself a paint stirring gizmo with the spiral configuration on the end. Put that on the end of your drill and stir your material, no matter what it is, for at least three minutes in a quart sized can. More for a gallon, even more for a five gallon. Don't whip any air into your material when you are stirring. Air will make bubble in your finish, even after application. A low mix speed works fine. When the semi gloss, satin clear coat is properly mixed it will look like clear amber in the can. Some clear flats look a bit cloudy, but consistent. Never white. Robert |

I do have a paint mixer bit, but it seemed aggressive for a quart of poly. My work area is a partially heated enclosed porch, the temp was lower than RT. My poly experience had been with "gloss" or "stain" and used right after purchase. Now I'm confident that poor mixing was my problem. Thanks for responding. |

Last winter I had the same situation with Krylon sprays. I had a few
small projects and decided to spray bomb them with clear over Minwax water base stain. The boxes I wanted to spray were a week dry but both Krylon Acrylic Crystal Clear & Trilpe-Thick Crystal Clear Glaze both fogger up something terrible after following the directions to the letter. Through e-mail communication the conclusion was humidity. I live in Florida which is notorious for humidity but it was winter so I'd say it was about 40 to 50%, which is considered low for here. The plus side worth noting are the people at Krylon were very apologetic and even offered to send me two new cans, which I guess I can still get but for small projects I'll stick with Rust-Oleum Lacquer High Luster, which I never had a problem with even in summer...

Waited a week and did another room and the same problem again! Just no sheen at all! Maybe I have to buy small cans, so it's a new can each time. Depressing! I still have 4 rooms and a landing to go. I was wondering if I shouldn't be wiping my brush on the side of the can as I go? I just don't understand! |

It's hard to believe that anything that is formulated to be fast drying, can at the same time, have a long shelf life - unless it's a catalyzed finish. Something has to give and once you introduce air into the can, the product is going to start doing exactly what it was designed to do. -- -Mike- |

Just bought a spray can of minwax polyurathane for my final coat on an old walnut table. Previous coats had been minwax polyurathane fast drying rub-on with sanding in between. I live in a arid region of the country, so I know moisture is not a problem. The spray can of minwax left a milky, rough finish. I will sand it off tomorrow and go back to my hand rub routine. Very disappointing product and waste of money!

Absolutely correct - and Karl claims he don't know nuthin' 'bout spraying finishes... I can only say that I strenuously agree with him on this! I learned a long time ago that the smart guys that they hire to come up with this crap know a lot more than me, and so I trust in what they say. Of course, I learned that the hard way... Go back, shake well and test it on a board to see if the the blush still happens. I'll bet it does not. Poly does not generally blush. That's more a lacquer characteristic. Even with lacquer, it's related to humidity and that is not an issue for this poster. I have to believe (at first guess with minimal information), that the problem really does lie in the proper use of the product. -- -Mike- |

Don't have that much time to waste ... In the course of this entire dialog, I just became aware of one of those perspective things. When I think of poly, I think brush application - because that's how I usually apply poly to wood. I'm systematic in how I do that - very wet coats, spread - not brushed on the work piece. So - (my bad...) that's what I think of by default when poly topics come up. I guess I haven't figured out yet, how to think outside of my own box... Now, having finally realized that you might just be talking about spraying with rattle cans (spraying to me of course, means a big ass compressor and really good spray guns...), I'm suddenly struck by one of those light bulb moments.

Minwax fast drying polyurethane dries to white haze
Despite an old post, a relevant aspect (maybe) can be gleaned. Stirring properly and following can instructions may have been a part of the OP's problem, but I think moisture contributed to the issue. The OP said the wood was stored in the garage (in essence, outdoors, cold temps?), yet the work place was a "heated porch". He/she said the wood "... "feels" moist". He/she may not have allowed the wood's temp to acclimate to the work place's higher temp, hence, there may (likely?) had been slight condensation on the wood surface. I assume, quick condensation formed on the can's lid, also, apparently (again, I assume, by what the OP said) immediately after opening. In the OP's (I assume) colder climate location, plus the garage vs heated porch immediate environment, there may have been a significant temp difference to cause some condensation, despite his/hers generally dry climate. A significant temp difference, from garage to work place, can negate the general dry climate arena. Op said he/she had used the product, before, with no problems. What might have been the difference in the two work scenarios, circumstances.... Weather conditions, prep conditions, temp acclimation, something else, including can instructions? Where was the poly stored? Was its temperature greatly different from the wood and/or porch area, also? ...and compare this to the previous "no problem" usage. Sonny |

Just to set the record... this is what my newsreader shows as the original post (despite it being long aged...). I don't see anything in the OP that talks about storage in the garage, heated porches, cold temps, feeling moist, etc. Are you referencing a different post when you refer to the OP?

Set aside at room temperature and it immediately starts to look like I coated the wood in white soap. What the hey. After a couple hours no change. Almost looks like I painted the wood with white lead. I've used this produce before without problems, but it "might" be some kind of reaction with the wood. The wood was purchased at a farm sale in a batch of other hard woods that could have been over 30 years old. Some mahogany and what I thought was teak but I can't imagine what the heck happened. Maybe return the can to the store and try another batch. ************* End of Included Text ****************** -- -Mike- |

Mike, here's what I'm seeing, additional to the original post: bw, the poster's follow-up posts: "----------------------------------------------- Doubt it, it's been very dry around here this winter. Wood stored on high rack in garage. Test piece was sanded as usual along the grain. Wood does "feel" moist or greasy to touch. It might be that I'm not that experienced with tropical wood. Tested another piece with mineral oil and it really looks good so I'll skip the poly." Then he later posted: "Excellent !! I do have a paint mixer bit, but it seemed aggressive for a quart of poly. My work area is a partially heated enclosed porch, the temp was lower than RT. My poly experience had been with "gloss" or "stain" and used right after purchase. Now I'm confident that poor mixing was my problem. Thanks for responding." Sonny |
