Concrete can be colored by staining using several different methods that are specific to your applications. The versatility of concrete stain comes in its ability to offer a wide range of colors. When it comes to possible design options, singular colors are just the tip of the ice burg. Another popular option is a patterned effect that is achieved through the use of stenciling. Simple stencils might deliver a checkerboard appearance or an exterior border design around the base of your floor.
