We never really had issues with the CVT floor in the old pizza place. Although, I know the wax or sealant the contractor used was very expensive, and there were several coatings applied. I was only a 1/3 partner with a husband and wife (the other 2/3), so I didn’t exactly have much pull with anything or I’d have done it myself. Despite having a lot of traffic and a lot of things being moved around on the floor (tables, cold prep box, etc.), we never really had any problems with it.
Is it just the surface coating you’re having trouble with? Or are you losing tiles also? Is the coating coming up in chips or flakes, or just wearing through?
