When decorating, it is easy to stick cement on the marble when paving the marble. If the cement stains are not cleaned well, it will affect the appearance of the decoration. Then, how to remove the cement stains on the marble? Next, let's take a look with Jiahao editor Look.
1, 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, use a rag to moisten the bio-cement cleaning agent to wipe the marble directly, and then wet the rag to wipe off the cleaning agent adhering to the marble surface. 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 off with a cloth. Wipe it again with a clean damp cloth.
2, scraper method
is attached to the surface of the marble and embedded with a spatula to remove the cement.
3, the permeability of the stone
When discussing how to remove the cement spots of stone, we must first popularize an important characteristic of stone, namely permeability. This characteristic of stone is completely different from the characteristic of zero water permeability of ceramics and glass. If a colored liquid is used to treat cement spots, be careful about whether it will penetrate into it and cause color difference. Some cleaning agents penetrate into the marble, leaving irreparable staining residues. Especially light-colored jazz white, Guangxi white and other products.
4. Polishing method
The process of this method may be more complicated, so it is recommended to be handled by professionals.
5. Special cleaning agent for stone
These products can decompose the organic pollution on the surface of the stone and remove the surface protective agent. If necessary, the cleaning agent can be mixed with detergent powder, which can prolong the reaction time of the compound and absorb stains into the paste.
Before using the compound, first 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.
