Apply two to three additional coats of full-strength polyurethane, sanding between each coat.

Can you put too many coats of polyurethane?
Generally, more than 3 coats of poly doesn’t do much good. It’s really not needed nor recommended. Each additional coat needs to be buffed so you are kind of buffing off half of the previous layer. So 4 coats is more like 3.5 coats.
Do you really need 3 coats of polyurethane?

Is 2 coats of polyurethane enough?

How do you fix imperfections in polyurethane?

Does polyurethane hide sanding marks?
Polyurethane isn’t going to do a very good job hiding very obvious scratches. However, if you have scratches in a semi-gloss or satin finish, polyurethane might be able to hide very tiny marks. If the scratches are very noticeable, then you can try wet-sanding the wood to remove them.

Are you supposed to sand between coats of polyurethane?
Allow each coat to dry fully. To give the subsequent poly layers something to bond to, sand lightly between coats with 320-grit sandpaper wrapped around a hard block. Note: The first coat needs the most sanding to appear smooth; don’t worry if it doesn’t look as flawless as you’d like at first.
How do you smooth the final coat of polyurethane?
