1. The permeability of stone
When discussing how to remove the cement spots of stone, one must first popularize an important characteristic of stone, namely permeability. This feature of stone is completely different from the zero water permeability feature of ceramics and glass. If colored liquid is used to treat cement spots, be careful about whether it will penetrate into it and cause color difference. Some cleaners penetrate into the marble, leaving irreparable staining residues. Especially light-colored jazz white, Guangxi white and other products.
2. Cement cleaning agent
Marble contaminates the cement. It is recommended to use a cleaning agent that does not react with the calcium carbonate component of the marble: biological cement cleaning agent. The method of using bio-cement cleaning agent is as follows: 1. For general cement ash, you can use a rag to moisten the bio-cement cleaning agent to wipe the marble directly, and then wipe off the cleaning agent adhering to the marble surface with the rag. 2. For the thicker cement layer on the marble surface, you can use the biological cement cleaning agent to spray directly, wait for a certain period of time, wait for the marble surface cement to be softened, and then rinse with water or wipe it off with a cloth. Wipe it again with a clean damp cloth.
3. Scraper method
Scraper method is attached to the marble surface and embedded with a spatula to remove the cement.
4. Special cleaning agent for stone
This type of product can decompose the organic pollution on the stone surface and remove the surface protective agent. If necessary, the cleaning agent can be mixed with the detergent powder to extend the reaction time of the compound and absorb the stains into the paste.
Before using the compound, test a small area such as a corner of a wall that is not conspicuous, and make sure that the stone surface will not be covered with dark flower marks. It is relatively easy to remove minor scratches, and there are many polishing powders on the market. However, when using polishing powder, it is usually necessary to use a polishing machine or a single wiper.
5. Polishing method
The process of this method may be more complicated, so it is recommended to be handled by professionals.
