Why is my polyurethane rough?
2 Answers. Usually when varnish makes a surface rough, it’s either that it’s picked up dust during the drying process, or it was being brushed/wiped too long after application.
Is water based polyurethane self leveling?
Water-based polyurethane versions dry much more quickly, are a bit more self-leveling, and have less odor when applying than oil-based versions. On the downside, water-based poly tends to raise the grain of the wood, is susceptible to watermarks, and can be temperamental when applied over some wood stains.
What happens if you don’t sand between coats of polyurethane?

How do you level polyurethane?
When thoroughly dry if it looks real close to what you want I would wet sand it with 1500 grit or finer sandpaper and buff the finish with rubbing compound. If it doesn’t look quite right you could wet sand it with 400 grit sandpaper and apply another coat before going to the 1500 grit.
