Just read through the thread. Nice work. I did the same to my garage a few years back. Textured, primed, and painted all the walls. Epoxied the floors myself with all the seams sealed just like yours. Installed my hyooge compressor and hose reel, plus tons of lighting, huge shelving units, lots of electrical, etc. My small 20x24 garage is very useful now - it gets shit done!
