I had mine done May 2022. 3 car garage for the house that I bought (not sure of the sq footage). I had it done before I moved any stuff into the garage. Whole lot easier to do it without moving items out of the garage for a few days.
I paid $4500 for everything. The house was built in 1998 and still had the original garage floor. No cracks or pits, but definitely had oil stains. I was told that most of my fee was due to prep work. It has a 20 year warranty. I am glad I had it done. I plan to live here until I retire so it was worth getting done for me.
Mine is a polyurea coating, not epoxy. Was told it was more durable than epoxy and bonds better. Maybe that’s what Browndog is referring to.
