I have a really long (about 20') uneven crack in my cement garage floor. Not only is it jagged, but the sides of the crack range from flat to about 1/2" high. I want to level the sides of the crack, seal it, and end up with a flat floor. I'm not sure what the best way to do this is. I'm thinking about either grinding or chiseling down the high side, then applying CrackFix, then applying some sort of topcoat to make it smooth. Anyone have any better ideas?
I'm not going to put a floor over it, I just want it to look good again. I picked CrackFix because it looks like it will seal and level at least the crack, but once I break up the high side I still need to level and smooth the whole area.
