Inc, thanks. Epoxy coating the whole garage floor will solve the cosmetic issue, right?
Yes, the epoxy coating will cover it up nicely. The company will even patch up the concrete crack before apply the coating.
Does your garage have the scored lines like the pic below?
My previous home's garage is just a big flat continues surface without any scored lines and it display many hairline cracks. My new home and many of new home here in Irvine have scored line in the garage floor to divert the hairline crack away from the main surface.
