1. The physical baking method
This method is the use of high temperature heat separate out water of alkali - silica body, so that it becomes solid, then using stone conservation agent to waterproofing. Because of this method just handle surface of stone, so it will absorb moisture from bottom of stone and regenerated water spots.
2. The chemical cleaning method
This method is use stone water spots scavenger, removal or destruction of stone plaques formed in water base or alkali - silica gel (CSH), they lost the ability to absorb moisture, so can removed water spot.
3. The cleaning baking synthesis method
Use stone water spots scavenger remove or destroy silica gel (C-S-H) of water spot, and then use dried stone baking method to dry water.
4. Brightening toner method
Brightening toner method is that the lighter part stone color of water stone lesions deepened to reach the dark part of the same or close to the color of the stone, so as to achieve beautiful decorative.
Currently, it is no valid for governance of water spots , this is an urgent problem in our industry to solve. In view of this, to prevent water spots is particularly important.
