There are a variety of techniques that can be used to create different effects in the staining and dying of concrete. Multiple applications of concrete stain or dye can intensify colors, while layering the colors will give a non-uniform ‘mottled’ look. These stain and dye systems are popular for commercial and retail environments with light to medium traffic. Sealers, hardeners, and densifiers are specifically developed to protect the beauty of multi-colored surfaces, as well as increase performance and durability of the concrete floor.
