Reddit mentions of Basic Coatings STREETSHOE Waterbased Wood Floor Finish Satin 1 Gallon

That's hardwood, my man! Refinish that floor!

Rent a drum sander and a floor edger, start at 60 and sand in line with the boards, 80 diagonally across, then 120 in line. Stain it up (I prefer Old Masters - avoid Minwax), wait 72 hours, then seal with a catalyzed two-stage sealer like StreetShoe NXT. Anything from General Finishes is also great stuff (both their stains and sealers are great).

After you do your first pass with 60 grit, fill any gaps, nail holes from the tack strip, or imperfections with a trowelable wood floor filler like Bona Pacific Filler or Rust-Oleum Parks (NO PLASTIC WOOD ON FLOORS). If you need to plug holes where wiring may have been passed through in the past, use corks.

Also a good time to refinish or replace baseboard. The whole project will add good value to your home and will look so much better than carpet.

What sander are you renting? It's most likely an ez-8 which are absolutely useless. 110v machines are not aggressive enough and will take forever. Also if you cant get your hands on a multidisk or trio or even a varathane sander you will want to buy screens and rent a buffer. Finish big machine at 80 grit. Then finish all edging and then palm sand anywhere you edged making sure to get all scratch out. I would not suggest staining as that is extremely difficult for a beginner to pull off with no scratch and no lap marks etc. Also any imperfections you made with the drum sander or edger will show up way more. Don't use any stain or finish found at big box stores, it is honestly useless and not durable at all the minwax stains take like 3 days to dry and fine print on can says not for use on floors. The varathane stains have compatibility problems where if you use a water based finish on top it will peel. If you are going to stain do not do more than one coat, that will also cause adhesion issues with the finish and it will peel. This is a very good finish, extremely durable and will last. Use the basic coatings sealer underneath or you'll end up with aide bonding and get while lines everywhere with the movement of the wood. I would suggest some oil based finishes such as bona woodline or Sampson wood armour but those products can't really be shipped because of VOC issues. Itll cost a lot more. Your local hardwood distributor may sell some to you, but usually you have to be a flooring contractor with an account with them to buy products, but you may get lucky if you ask. If you can get some oil based finish I would recommend bona dry fast sealer and bona woodline or Sampson wood armour. Much much much tougher than anything home depot or Lowe's sells, but ultimately the streetshoe 275 will be the toughest finish without going moisture cure or UV cure.
