Bob Harris of decorative concrete institute explains how you can remove your tiled or carpeted flooring for a concrete substitute. He suggests when your removing carpeting that it can be very heavy and advises you to hire someone who can lift and carry it out, or rent a dumpster for easy take away. He states that after the carpet is removed you'll need to remove the adhesive from the floor. You can do this by stripping or grinding, and at other times the use of harsh chemicals may be needed. Once the adhesive is removed Bob says to look over the floor for any holes left over from the tax strips or cracks in the floor. They then need to be filled with a cement based patching compound and then apply a thin layer of cement for a smooth end result.
