Do you sand the final coat of polyurethane?
You shouldn’t have to sand the final coat.
You apply the final coat, let it dry and you’re done.

If you are going to do that you might as well use a gloss finish..
Is 2 coats of polyurethane enough?
You are best off using 3 coats of water based polyurethane for the best results. … Not only is water borne polyurethane thinner, but it also raises the grain of the wood, so the floors can sometimes feel rough with just 2 coats of poly (especially if it’s a cheap brand of poly).
How many coats of polyurethane is too much?
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.
Can I use a foam brush to apply polyurethane?

How do you keep polyurethane from peeling?
Make sure you have higher humidity in the air when you finish. Use a “swamp cooler,” add some mist, or do whatever it takes. Once the finish has cured out, extra humidity would no longer be needed. Finally, extreme heat/cool cycles can influence peeling.
Can you use steel wool between coats of polyurethane?
Using steel wool or sand paper allows you to create a uniform surface for the next coat of polyurethane, which generally looks nicer, more professionally, etc. In my experience, assuming the finish is dry, there isn’t a difference other than the coarseness of the sand paper or steel wool.
What happens if you don’t sand between coats of polyurethane?
Failing to sand between coats of polyurethane does not have a significant impact on the finish. Even so, I still advise that you sand between the coats when applying polyurethane as this will help increase the adhesion between the layers to give you a more level finish.
Do you really need 3 coats of polyurethane?
