Installing durable floors in retail or medical or any place else is important. In the retail environment, they want that floor to hold up to the pedestrian traffic for a very long time, which is probably 10 to 15 years, which is the typical lease for those spaces so we need to design a floor that’s going to hold up to that and be very easily cleaned, they do not want to spend a lot of time cleaning, they don’t want a lot of cost there. In the medical environment, quite different. There we need to have a floor that’s going to hold up to very severe and astringent based cleaners that are going to attack that floor and it needs to resist that. These need to be impervious to any type of invasion by bacteria, so they need to be super smooth. So both floors are designed very differently (but) and for different purposes but the technology exists to do either and we do a lot of both.
