I understand polished porcelain. Honed porcelain is something I have not heard of before your post. Can you explain honed porcelain?I agree with Mike's answers-Just adding we wanted to find something that would solve the issue of getting a technician off a job when a porcelain tile cleaning job went bad. The products that will be in the kit will be a two step process for honed porcelain and a three step process for polished porcelain. As Mike explained one step used even by hand can repair blemishes while the other steps can remove some lite wear and produce a polish. I agree with you Tom there is more to learn here for sure.
If this phenomenon starts by removing a weak coating then why not fully strip it and apply a better coating that is translucent?
