SunBless may be applied on concrete floors too. As the coating of SunBless is relatively soft, any activities like walking on the floor wearing high-heel shoes or dragging of any sharp and heavy object on the floor, could allow minute dirt particles to enter the coated layer through scratches, thus making the surface appear dirty.
If you walk with ordinary shoes it will not wear out at least for 6 months to one year. However, we do not recommend SunBless for floor application in factories. SunBless may be very effective on floors where people walk without shoes or sandals.
