How to Fix a Cloudy Finish After Polyurethane?
Asked by SawdustDancer92
I recently applied a water-based polyurethane, but I noticed some small bumps on the final coat, likely from dust. After sanding it down with 3000 grit sandpaper, the bumps are gone, but now there's a white shine to the finish. Is there a way to fix this cloudiness, or should I just apply another coat?

Definitely consider reapplying a coat if the buffing doesn’t do the trick. It’s a safe way to even out the finish. Just remember to sand lightly between coats for the best results. And if you’re having issues with thickness, thinning the poly is a great call before applying, just follow the manufacturer’s guidelines!

It sounds like you’re dealing with a common issue! The white shine usually indicates clouding due to moisture or too many layers applied too thick. You can try to buff it out with a little polishing compound, which might help restore the clarity. If it doesn't work, yeah, a thin new coat might be your best bet. Just make sure to thin it a bit to avoid the bumps next time!
FixItFella: Good tip! Just be careful with the amount you thin it. Start with a small ratio and test it out first to see how it flows.
