Wear heavy duty work gloves and safety goggles while busting through the tile. The shards are quite sharp and may cause severe injuries.
Position a cold chisel upright on the tile.
Hit the chisel with a sledgehammer that weighs about three pounds. This will crumble the tile and mortar. Don't go beyond the depth of the tar paper underneath the mortar bed. (
Repeat the action with the cold chisel and sledgehammer until all the mortar bed is loose.
Pry the mortar bed and tile sections up with a large flatbar tool.
Transport the debris to a recycling center to discard it.
