Why does the stone have color differences?

Since the color of the stone is naturally formed, the color quality is determined by the pigment ions contained in the stone and the internal structure. At the same time, the sequence of formation of different minerals that make up stone will also affect the change of color, which is what we call color difference. Therefore, when using decorative natural stone, we often encounter the problem of color difference.

According to the different stone structures and color characteristics, the stone surface with color differences are roughly classified into two categories, and different solutions are proposed accordingly:

 

1、 Stone of the same color system refers to a kind of stone with the same structure and characteristics and the same or similar color components.

For the color difference between such stones, we suggest using color enhancing stone curing agent (also known as a wet color agent and fresh-keeping agent) for treatment. The color-increasing stone curing agent is applied to the adjustment of small color differences between stones of the same color system and the color-increasing treatment of dark stones with breathing pores, such as marble, granite, sandstone, and slate, which are worn, faded, and dim. The effect of adding color to light-colored stones is not obvious. As it is not easy to fade after coloring, it is recommended to do small sample experiments first and then carry out large-area construction after confirming the effect.

2、 Stones of different color systems refer to a kind of stones with completely different structures and characteristics, and completely different or very different color components.

For the color difference between them, we suggest using the coloring method (staining) to deal with it. At present, there are about 20 methods of stone coloring, most of which require specific equipment or sites. This is not practical for the stone maintenance industry.

After many years of experience, it is considered that it is a simple, convenient, and effective way to use stone coloring agents for coloring treatment. However, as the stone is not easy to be removed once colored, it is recommended that professional technicians carry out the construction to avoid unnecessary losses.
