Cover your doorways with your plastic dropcloths. Use your painter’s tape to hold the edges of your dropcloths on your door frames. If you attach your tape to your paint, you run the risk of pulling some of your paint off your wall when you remove your dropcloths.
Insert the scraper blade into the end of your electric hammer chisel. Follow the manufacturer's instructions that will show you how to secure your blade.
Hold your hammer chisel so that your scraper blade is at a 30-degree angle to your concrete floor.
Turn the power to your hammer chisel on. Place the blade at the bottom edge of your tile adhesive. The blade will move in a hammering, or back-and-forth, motion, pushing the tile adhesive off the surface of your concrete.
Sweep up the majority of the scraped tile adhesive with your broom. Use your shop vacuum to finish cleaning up the adhesive.
