Fortunately, learning how to seal concrete is something most DIY-savvy homeowners can tackle.

Polished concrete gets its glass-like finish from several rounds of polishing, using increasingly finer grit diamond grinding pads. The concrete’s hardness will determine which grits you need to get your desired finish. The densifier and sealer also contribute to the look of the final floor, so either talk to a concrete pro (or hire one) to achieve the right concrete floor finish.
