Is this a joke?
If the picture above is your garage, why the hell do you need to paint the floor?
It looks like a hospital now, haven't seen many floors as nice as that man.
Just slap a nice Harley sticker on the wall and call it a day.
Do you know what is on your floor now? Looks like paint? The epoxy is good, if done right...every stage is important, just like painting, you can't skimp on any one of the stages. If an epoxy is done right it will outlast you. Too bad if it is paint 'cause you have tO GET IT ALL OFF, you have to start with a raw concrete floor in order to have anything to adhere to it. It can be done, but don't even bother to try it without removing every inch of whatever is on the floor now. Anybody who is unhappy with epoxy has not had it done right, they skipped a stage or did not do a stage properly. There are other thing on the market now that you may be interested in that are similar to epoxy,(I dont know what they are called) so maybe google it. If what you have is half decent I would not screw with it. (my opinion...really, it looks o.k.}
Actually the garage floor above is mine, and it wore well for about 3 years.
Then one morning I went to roll the bike out to wash it after being caught in the rain the night before, and it pulled a large piece of the epoxy up, so this year I decided to tile the floor.....
The garage is actually 10' X 24', but I didn't feel like moving the bench and tool box, so I only had to cover 10' X 22'
I bought the flooring off Kijiji from Clarion Canada after they used it for 1 trade show, total cost to me was $200.00, I couldn't pass it up.
