Natural stone, especially natural marble, does need to be sealed. Here are the reasons and methods for sealing natural stone:
Reasons for Sealing
Porosity: Natural stone, particularly marble, is porous. This porosity makes it susceptible to water and oil infiltration, as well as stain formation. Sealing helps to prevent these issues, thereby extending the lifespan of the stone.
Stain Prevention: Sealing natural stone can effectively prevent stains from penetrating and damaging the surface, maintaining the brightness and aesthetic appeal of the stone.
Ease of Cleaning: Sealed natural stone is easier to clean, reducing cleaning time and effort.
Sealing Methods
Surface Preparation: Before sealing, the surface of the natural stone should be thoroughly cleaned to ensure it is dry and dust-free.
Selection of Sealant: Choose an appropriate sealant and follow the manufacturer's instructions for application.
Application Process: Generally, the sealant is applied to the surface of the natural stone and allowed to dry completely before any excess is wiped away. The sealant typically takes about 24 hours to dry completely.
Post-Sealing Care: After sealing, wait for 24 hours until the sealant is completely dry. During this period, avoid placing anything on the surface of the natural stone to prevent surface indentations or discoloration.
Additional Considerations
Avoid Harmful Cleaners: In daily use, avoid using acidic or alkaline cleaners, as they may damage the sealant layer on the surface of the natural stone and affect its sealing effect.
Bacterial Survival: When sealing natural stone, it is important to recognize that while stones cannot "breathe" like humans, they do need some degree of "ventilation" to allow bacteria to survive and reproduce within the stone. Therefore, choose a sealant that is compatible with the stone's natural properties.
In summary, sealing natural stone is an important step in maintaining its beauty and durability. By following the proper sealing methods and taking care of the stone after sealing, you can ensure that your natural stone surfaces remain in excellent condition for years to come.
