    I did some work filling in cracks with plastic wood that came out okay. I then applied water-based polyurethane (which is what is on the floor now). I then lightly sanded it and added another coat. Now it has this haze. Will this just wear away, or is there a way I can fix this?
    Thanks.

    I don't really have a clue, but did you stir the poly well? Looks like a satin or low sheen. House is up to temperature I assume?

    It's an old can of clean semi gloss. Do you think I should just buy a new one, lightly sand it again, and re-apply? Thanks.

    If the can was close to empty might you have dipped the brush to the bottom of the can and gotten material that wasn't stirred in?

    The finish appears cloudy or milky. Cause: • Applying finish over a coat that isn’t dry enough to be recoated yet. • Applying waterborne finish during very high relative humidity or over a floor that is too cold to be coated. •

    Cure: Abrade/screen and recoat, being sure to increase the dry time between coats. Check with a damp rag before abrading/reapplying finish to make sure the cloudiness has disappeared.

    What Nick said. Plus what was the dry time between coats and your Rh/temp?

    Thanks, everyone. The polyurethane was old. I bought a new small can and it looks much better.
