I painted mine, never again! I used floor paint recommended for garages, followed the instructions, prepped the floor, put two coats on, It looked good for a couple of years then started to flake. Once it started to flake everything that I had sat on the floor would get covered, I used to get covered in it when I was kneeling down, Any wind blowing through the garage would chuck it all up in the air, it was a nightmare. I ended up buying some cheap, interlocking, hard rubber matting from B&Q, I bought it just to cover up the flaky paint but it seems to do a pretty good job. Not sure if it was just crap paint that I used or the floor wasn't thoroughly cleaned that caused the problems but I personally wouldn't do it again, I read reviews some time after doing it where people had the same problem as I did. If you do it I would definitely recommend taking the time to search for a good quality paint and then have a look at the reviews.
