Pick a location to start removing your patio tile. This could either be at the center of the are or off to one of the sides. If these patio tiles are laid to the edge of the patio and there is no edging in place, it might be easier to start at the side. Another place to start is where the grout between the tiles is beginning to crack. This will make removal easier.
Don safety equipment, including goggles, kneepads and gloves. Wear a long-sleeved shirt and long pants while working.
Saw away the grout from around the edges of the first tile. Use a grout saw and grout cutting blade. With larger grout dimensions, you can use a rotary type tool with a cement or stone cutting blade. Remove as much of the grout with your chosen tool as possible.
Insert one end of a tile chisel underneath one side of the tile. Gently tap on the chisel to drive it underneath the tile. Move the chisel back and forth on that same side to loosen the tile from the adhesive underneath.
Repeat the process with the chisel on all sides of the tile. Gently tap on the chisel until the tile comes loose from the adhesive underneath.
Use a hammer drill and chisel attachment. If you don't care about saving any of the tiles and time is more important to you, attach a chisel bit to a hammer drill and begin chipping away at the tiles. The hammer drill works like a mini jackhammer and will make short work of the patio tiles.
Clean up any of the tile debris with the broom and dustpan. Use the chisel or hammer drill to scrape up any remaining bits of mortar, grout or adhesive.
