Disclaimer: I'm a Kitchen and Bath guy, which means I never have to deal with hardwood floor refinishing, because 99% of the time we're installing tile floors.

Anyways, we hired a sub and he refinished the floors in this kitchen that we're remodeling, however there are bubbles in the polyurethane. The HO noticed, and I told him the issue would get resolved. The floor guy said the following to me:

"The bubbles are typical, and will work themselves out with floor traffic."

This sounds like a lame excuse for poor workmanship, but that's just me. Wouldn't you guys suggest a buffing with a light grit sandpaper and one more coat of poly?

I've not heard that one either and NO I also am not a HW guy.

We've got some good ones here on the forum that will surely chime in soon.

My gut feel is something is fishy.

Yep screen & recoat. It occasionally happens to the best of us.

The bubbles come from either mixing products or a too thick application. My guess is he switch between incompatible products. Tell him he can either fix it now or wait till they work themselves out to get paid..
Bubbles happen for many reasons. Shaking finish instead of stirring introduces bubbles. Using a roller will introduce bubbles. Heck, I even get em occasionally with my lambs wool when it's overloaded. Nothing a screen & recoat won't fix.

Yes, screen and recoat. We do a lot of gym floors and I would say about 1/3 of the time when the flooring sub says he is done, I make him do a screen and one more coat. It's not a big deal.

So THIS



Is not true correct? Pin and others?

I was more interested in the "excuse" given.

Just curious.:thumbsup:
Bubbles in a dried finish will never work themselves out. They are locked in the resin now. The most they will happen is foot traffic will shear the top of the bubble off and leave a small hole.

Screen and recoat.

I love "when the bubbles work themselves out, you'll get paid." :laughing::laughing:

Bubbles can also be caused by not allowing the stain to dry adequately or coating while direct sunlight is hitting the floor... Whatever the cause, they are unacceptable.. Screen and recoat

Had the direct sunlight screw me on a job a few weeks back. 2 giant windows facing east & the morning sun blasted down on my wet finish. Took me a little bit to figure out why. We pulled down the blinds before we coated again.

Yep, the sun has gotten me more than once.. I've found myself taping rosin paper to windows to block it out when necessary.

No bubbles in any finish ever. You can thin, you can run a hair dryer (no heat). I haven't tried it since the reformulation last year, but I'll thin a product until shaking it, or scrubbing it in won't leave permanent bubbles.

Why the bubbles are present should be determined first before advising a recoat. If they are due to improperly dried undercoat a full resand is needed. If due sun or clean up minor contamination a recoat will suffice

That happened at my parents house too...bubbles all over the place. I asked them how the guy applied it and they said w a roller. Ive worked w resins quite a bit and have dealt with the bubble problem a lot. Im not saying the application process doesnt have anything to do with it but I agree w post that said the guy mixed it too fast. Thats where the bubbles come from.

The way I get the bubbles out of my mix is to hit it with a torch while its still in the bucket. I get bubbles no matter how slow i mix, so when Im done I pick the bucket up and drop it a few times to get the bubbles to the top and then i hit it with some mapp gas. It pops all the bubbles and goes on smoothe. Be careful tho because most of the stuff that bubbles is also flamable.

so when i say hit it with the torch i mean real quick. dont set the bucket on fire...lol... and if you do, just stir it or throw a towel over the bucket.
