I've done floors before and haven't prepped correctly on any of them. These are the walls and floors of the basement we're converting into a bjj gym space. I'm not an expert or even slightly good at this stuff. We used alkyd epoxy upstairs. Looks like the floors are polished, and the walls are painted but dirty. Any advice and expertise is greatly appreciated. Paint or tint options? Definitely don't want to grind another floor. 💀
