The process is simpler and involves less grinding, honing, and polishing steps. In terms of durability and benefits, polished concrete has a much longer lifetime expectancy and is much more durable, especially in areas with high traffic. We typically recommend sealed concrete as a more affordable alternative to polished concrete.
