The cement floor has been broken out. I used an expensive diamond blade (a good one costs about $40 at Home Depot) on an ancient 7" Sears Craftsman circular saw. I outlined the demolition area with a 1/2 inch cut and then broke up the floor with a rented electric jack hammer from A & A Rentals. Protective eyewear, a high quality mask, a plastic barrier to limit dispersion of dust, and a good shop vacuum for clean up are all absolute necessities. IMG 2268
