To the uninitiated, it may seem like an odd proposition to use concrete as a material for a countertop. Perhaps these people equate concrete with the rough, harsh-edged material in sidewalks and building structures. In reality, contractors use a fine, polished form of concrete to make a sturdy, natural and beautiful countertop that can resemble stone or tile.

Polishing Concrete

What's the secret to polishing concrete? Diamonds. High-tech polishing machines use diamond segments or discs to wear away the concrete surfaces to a given luster or smoothness. The polishing machines act as a sort of sandpaper for the concrete. It is not a quick process; concrete is a tough material. In fact, its toughness is the reason many people want to use it as a foundation for their countertops.

Once the first step of polishing is complete, contractors use even finer diamond bits to wear away at the concrete's surface. This is similar to woodworkers using fine sandpaper after the coarse work has been performed. The amount of fine polishing depends on the desired smoothness and shine.

Finally, contractors will use a traditional polishing agent on the surface of the countertop. Such compounds will evoke the final bit of shine required for a beautiful and workable countertop. Clients may be surprised by just how dazzling a slab of concrete can look.
