Wood – What grit sandpaper should I use to remove polyurethane from hardwood floors

hardwood-floor

I wanted to re-clear my hardwood floors in my home but I didn't know what grit sandpaper I needed to do so. What is the best sandpaper grit to use in removing the polyurethane coat on a hardwood floor?

Start with a rougher grit sandpaper and work your way down to a smooth paper. Generally I use three different papers. Rough to remove the majority of the varnish, medium to get the rest of the finish and smooth any larger wood issues, then a third run with a fine paper to make it all smooth.
