Grinding & Polishing
Generally, 150-200 Sq. Ft. can be done in a day. However, it varies depending upon health of the floor.
It usually takes a day to complete 300-400 sq ft.
Wall skirting is done by hand grinder using diamond pads/grits and in this process one person can only cover around 100-150 Sq.Ft area in a day.
Our stock answer is that your floor should stay looking good for one to three years. Some floors may last up to five years without requiring attention, but this would be in low traffic areas.
