The fine chromatic aberration of natural stone is still widespread. Usually people can reduce the bad color sense of stone through the management control in construction process and the post construction treatment of stone maintenance enterprises, so as to achieve the best appearance effect of engineering.

How to prevent large area color difference between stone and stone?

Ensure the use of stone in the same quarry, pre - typesetting according to the number of pre - numbered, according to the design requirements of the color selection. In pre - typesetting, the same and similar colors should be arranged together, and through the natural transition of color and lustre, a part of the material with larger color difference is arranged to be typesetting.

How to deal with the color difference between the exterior wall and the stone?

The color difference treatment can be roughly divided into the embellishment method, the chromatism method, the dyeing method and the color modification method.

1, embellishment: through the water splashing test, the stone in the immersion condition without color difference or color difference is not obvious, you can use the color method. That is, the stone embellishment will be used to polish the shallowly colored stone to remove the chromatic aberration.

2, the color promoting method is: we can't handle the chromatic aberration through the coloring method, but the whole stone is more yellow. We can try to use the stone yellowing agent to promote the yellow color to eliminate the chromatic aberration.

3, dyeing method: for stone color difference that can not be adjusted by chromatic aberration and color changing method, we must use stone dyeing agent to dye the light colored stone and eliminate the chromatic aberration.

4, the subtractive reduction principle: Dr. Shi stone hypochromic agent, metal ions at the reduction of metal ions to achieve the low stone or stone fade to blue. This method does not affect the luminosity of the stone surface and the material of stone. It is an ideal material for the treatment of stone chromatic aberration.
