We can polish the surface of an existing concrete slab using engineered floor grinders fitted with industrial diamonds. During this process, the concrete is honed and polished using progressively finer grits of diamond abrasives until the floor reaches the desired level of shine.
However, with sealed concrete the gloss is achieved from topical sealer. The process is impeller 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.
