Thank for you reply gti16vman!!!
If you look at the picture you can see a seam in the concrete. Would it be ok the do the right side at the seam and then do the left after? I was thinking this would kind of hide doing one side at a time.
I'm going to try to fix the job our so called builder did to the garage floor before we moved into our new house. I didn't have time to do anything to the garage floor before we moved in so now that it's full I have a few questions. It looks like the floor is painted with some cheap flat paint...
