Minwax fast drying polyurethane dries to white haze

replying to bw, frustrated refinisher wrote: Hello, I know this is an old post but I'm having the same kind of problem. I've been refinishing a bathroom vanity, 3 pieces, and thought I was on my last coat of Oil Fast Drying by Minwax.semi-gloss but I got alot of bubbles even though I was doing all of the correct steps. I used Oil Zar stain. Anyway, when I lightly sanded w/220, everything was covered with sanding residue which I vacuumed, wiped w/dry microfiber cloth, then Kleen Green odorless mineral spirits but still looked greyish. I googled @ the MS and saw alot of complaints @it so I got the other Kleen OMS & wiped with microfiber cloth. Still looked the same when OMS dried. I went ahead & slightly thinned poly w/OMS. Minimal bubbles but it dried with a milk finish that looks like its under this last coat. I had already

2 coats unthinned & didn"t have a problem except for bubbles, no residue. I didnt have this problem in MB but I did all the doors, drawers,mirrors & light strip in my finished basement. I don't remember if it rained that day. Everything was dry but I did use a different brush this time that had been used before on walls, waterbased, but the first brush was used the same way & cleaned the same way. I presoaked the brush this time in OMS, something I picked up reading all these sites. Do I have to sand it all off? I've tried the heat gun but didn't see much difference & that was maybe 4 days ago & I keep checking it & it's not going away. The Zar oil stain is merlot, so the milkyness really stands out. I'm a perfectionist so I can't just leave it like this!!! Some posts say just put another coat on & that will make it go away, but I'm worried it'll just be more I have to remove. I bought a new Wooster Silver Tipped brush made for oil as was the other brush I used. I'm sorry this is so long but wanted to give all the info I could. Also, slowly stirred poly & tried to go slow & not overbrush, but has to tip off because of bubbles. Thank you very much in advance!!! PS I've refinished several pieces before & never had this problem.

I'll go down & check on them tomorrow to see if it worked or have to get denatured alcohol?? Also I can still see little rings everywhere where there were bubbles that I sanded smooth. How do I fix that?I've already had sanded thru in several places & tried to touch up with Minwax marker but it wipes right off. This was a brand new vanity that wasn't stained around molding but I didn't notice in time so I've been trying to fix it ever since.. I appreciate any idea's You may have!!Thank's again!!!

Here's an idea:

Stay away from Minwax products.

Having said that, I do use their Wipe-On Poly, but that's about it.

I did use Zar oil stain but I didn't thiing that covered very well, blotchy...I just went back down to check & most of the haze is gone& looks like most of the poly as well. I want to cover over those sanded bubble marks, little circles that remain after sanding smooth. Not sure if I should wipe w/more acetone, oms, or buy denatured alcohol & if one of those don't remove them & touch up my sand thru's w/another coat of stain or just put on more poly?? Sorry but this has been my first time posting but I've been reading these for months...Thanks again & if anyone else has info to correct, please contact me ASAP!! Your help is much appreciated!!

This is an EASY fix!! The same thing happened to some interior doors I had stained and applied the same polyurethane to. Just get a blow dryer and go over the hazy areas. It takes a little time, but works like magic and stays looking like new. Wish I would have known this years ago when I had the sa me problem, stripped down everything, and started over ?

oor with white streaks. It was like a chemical reaction craziness. Whatever the cause was, I used a hair dryer. With the hottest setting, I took time . With patience, the streaks went away like a miracle. It was after 24 hou rs of drying. If I had use the hot air earlier, it might have taken less t ime. But hot air works.

After a week of babying a dining room set to get it just perfect before var nishing, we applied this MinWax product and.... white streaks everywhere! T hanks to Google and all of you here, I did as you suggested, and used a hai rdryer on the varnish less than an hour after the streaks appeared. It took only a few minutes, it now looks beautiful! Thank you to all of you who po st and share your experience!

Thank you for this tip!! I had a lot of white left over on some night stand s I'm working on and I panicked, thinking I would have to start from scratc h. I'm so glad I read this post - the hair dryer was such an easy fix!

I just found out from MinWax they have a problem with their stain and polyurethane. They call it "entrapment". This happens when recovering an old minwax surface. Their solution is to sand down to bare wood and start over.

I have never trusted or been happy with any MinWax product, except that their finishing wax is a good screw lubricant.

They do have good marketing though

I just opened a can of minwax semi gloss clear poly and the can was mlky to look at not clear. I had just finished a can that was clear to look at not milky so it sounds to me deftective am returning the can. And trying another. Need to call minwax too.

WHAT kind of Minwad did you buy, Both times?

A water based poly in my experience ALWAYS looks milky in the can. Applied, it will dry crystal clear.

If your previous can was clear, and properly stirred it was likely an oil based finish.

If your finish dried with a milky haze you likely had a moisture problem.
