Nevertheless, relatively new, lighter mixes of cement designed for interior applications now provide for a wide variety of interior applications and custom finishes. Unlike stone, travertine, marble or granite, concrete can be custom stained during manufacturing to produce any color desired. Multiple layers of color glazes or waxes applied in several applications produce aged surfaces, similar to faux finishing techniques. And, the effect of sandstone or limestone can be achieved by leaving the natural air holes after the initial pour, creating a more organic appearance. Concrete offers great flexibility including the ability to add materials such as glass, marble chips, stones or other insets such as copper or other unusual imprints to create highly individualized and unique surfaces.
Several precautions are necessary when using concrete for work-surfaces.
Concrete surfaces need to be reinforced with steel mesh or steel rebar. Non-abrasive cleansers should never be used since they can also damage the surface. And, concrete does not respond well to the localized heat, therefore, hot pads are recommended. The flexibility of concrete makes it suitable for a wide variety of applications including work-surfaces, hearths, tables, benches, planters, and wall tiles. Nevertheless, when damage occurs concrete surfaces can be re-sanded, filled and sealed to restore the finish.
