The cost of polished concrete can vary depending on the current surface. If there is a lot of surface preparation involved, then the cost will be more. Are there tiles that need to be removed? Is there glue or paint currently on the floor? Are there cracks that need to be repaired? Many times the existing slab needs work done to it before it can be polished. This can make the job more expensive. In New Jersey, depending on the space, jobs can range from $3.75/square foot to $7.00/square foot for polished concrete
