Stone is used to do the decoration of the building, to a large extent is to use its excellent physical properties, especially its rich color, but also other materials. But as a result of the color of stone material is natural form, chromatism stand or fall by the pigment ion that stone material place contains and internal structure place of decision. At the same time, the sequence that the different mineral place that makes up stone material forms is different also can affect the change of color, this is what we say chromatic aberration. So, we often encounter the problem of color difference when using adornment stone material. According to the different structure and color characteristics of stone, we will have the color difference phenomenon of decorative stone roughly classified into two categories, and put forward different solutions:

One, the stone material of same color fastness same color fastness is to point to have same structure and characteristic, and the kind of stone material with same or approximate color composition. For example: the big flower of shandong white hemp and medium flower, medium flower and floret, smooth face and wool face, new surface and old surface as well as upper and lower ore layer belong to the stone material of same color department. For the color difference between this kind of stone, we suggest the use of color - enhancing stone curing agent (also known as wet color agent, preservative agent) to process. The brightening type stone material curing agent is suitable for the brightening treatment of the dark type stone material with breathing micropores such as marble, granite, sandstone, SLATE, etc., which is used to adjust the color difference between the same color series and the phenomenon of wear and tear, fading and dimming. The effect that adds color to light color stone material is not quite apparent. As the color is not easy to fade, so, it is recommended to do a small sample experiment, after confirming the effect to do a large area of construction.

Two, the stone material of different color fastening different color fastening is to point to have completely different structure and characteristic, and color composition is completely different or the kind of stone material with big difference. For example: gold line cream-colored and new west cream-colored, Spanish cream-colored and white sand cream-colored, the stone material that belongs to different color department between shandong white hemp and American gray hemp. For the color difference between them, we suggest to use the coloring method (dyeing) to handle. At present, there are about 20 kinds of methods of coloring stone at home and abroad, most of which require specific equipment or sites. This is not in line with the actual stone maintenance industry. After years of experience, we think that the use of stone dyeing agent for coloring treatment is a simple and convenient and effective way. But, because the stone material is not easy to be cleared after coloring, so, the proposal undertakes construction by technical personnel, lest cause unnecessary loss.
