We decided to take the plunge and try out a product we were unfamiliar with and we couldn't be happier that we did. We debated, wondered and prevaricated for weeks and none of it was necessary. This stuff is pretty amazing!
I installed and refinished hardwood floors for few years so I'm familiar with stains and poly coats. Stepping outside of what I was comfortable with seemed ill-advised but honestly this application was more forgiving than polyurethane and stains.
We applied the monocoat 2c with a squirt bottle that I bought at a local grocery store and a buffer that I rented at home depot. We wiped the edge of an entire room and then squirted a line accross the floor and buffed it in. We worked our way out of each room and when we got to the door threshold we looked for any dry spots or buffer swirls and then just walk back in (with socks on) and squirted a little more and backed our way out to the door. It's kind of amazing. You certainly can't do that with poly. It is pretty labor intensive- lots of wiping the edges- but not a huge deal.
For those who are concerned about the "flat" finish we found that it's not nearly as "flat" as some reviews I read online(which I read a lot of). It has a luster instead of a sheen. I sent a picture to my mom and she texted back that if my grandmother was still alive that she would say "oh that looks so rich"!
I sanded down a 1917 heartwood pine floor with three coats of paint and some stain back to bare wood and I finished with 100 grit for the edger and the big machine. I didn't buff with a screen but I did hand sand with 100 grit along the entire edge- where the edger swirls met the big machine line. I considered going to 120 grit but I started with 24 grit, then 36, then 60, then 80, then 100, then I was tired!. But my floors were cupped, painted and generally just screwed. Point is- it turned out great and I'm not a rule follower. By the rules I should have finished with 120 and then buffed with a 120 screen (I think). Regardless, the finish feels better under bare feet than any poly coat I've ever felt.
We completed the project 2 weeks ago so I can't attest to the long term durability but based on how forgiving the application was I feel confident that we can spot repair any future damage. As far as I can tell we made a fantastic choice and if you can run a buffer and squirt goop out of an old ketchup bottle I think you're good.
