Hey guys, long time listener first time caller. I've been looking over the site the past few months in preparation of refinishing the floor in one of my rooms this Spring.

Everything is ready to go. I just have one question, (and forgive me if it's already been answered, I used search and nothing comes up) what grit of sandpaper should I use between coats of polyurethane? Thanks for any help provided.

use 120 grit screen for oil based..anything finer clogs and dies early.

if doing by hand use 150 grit paper
