Ok so whats suggested, for a real working garage floor? Itll be a real working garage - oil spills, I regularly (weekly) have the mig and oxy/acy out, never mind the grinders, chop saws etc....
I can't see the pretty tiles not catching fire, same wth the PVC and lino types.... most of the true porcelain/natural stone won't survive...
So what's left? Epoxy coatings?
