How to Install White Marble to Prevent Yellowing: Professional Tips Using 919 and 130

White marble is highly valued for its pure appearance and elegant texture, but during installation and use, yellowing is a common concern. To effectively prevent this issue, proper installation methods and the use of the right products are crucial. The key lies in the proper use of Hanshi 919 Stone Interface Back Glue Sealant and Hanshi 130 Anti-Efflorescence Additive.

1. Choosing the Right Products: The Roles of 919 and 130

To prevent white marble from yellowing, two key products should be used during installation:

• Hanshi 919 Stone Interface Back Glue Sealant: This product is specially designed for stone and tile, offering excellent waterproofing and anti-alkaline properties. It significantly enhances the bonding strength between the stone and the cement mortar, preventing moisture and alkaline substances from penetrating the stone surface, thus effectively preventing yellowing【14†source】【23†source】.

• Hanshi 130 Anti-Efflorescence Additive: This additive is specifically designed to prevent efflorescence, which is a major cause of yellowing, especially in humid environments. The 130 Anti-Efflorescence Additive locks in the alkaline substances within the cement mortar, preventing the formation of white deposits and keeping the stone clean and aesthetically pleasing【21†source】.

2. Preparation Before Installation

Before starting the installation, ensure that the underside and sides of the marble are dry and free of impurities. A clean surface will help 919 and 130 to perform optimally, providing long-lasting protection.

3. Key Steps During Installation

Step 1: Apply Hanshi 919 for Base Treatment

First, apply a uniform layer of Hanshi 919 Stone Interface Back Glue Sealant to the underside and sides of the white marble. This protective layer effectively blocks moisture, preventing it from entering the stone, and enhances the bonding strength between the stone and the cement. Make sure to cover all areas evenly, especially the edges, to avoid any gaps【14†source】【23†source】.

Step 2: Add Hanshi 130 to Prevent Efflorescence

In the cement mortar or tile adhesive prepared for marble installation, add an appropriate amount of Hanshi 130 Anti-Efflorescence Additive. It is recommended to mix Hanshi 130 with water in a 1:2 ratio to create a working solution, then add it to the cement mortar and stir thoroughly. The treated mortar not only has high bonding strength but also effectively locks in alkaline substances, preventing them from seeping through the stone and causing yellowing【21†source】.

4. Post-Installation Considerations

After installation, ensure that the marble is allowed to fully cure in a dry and ventilated environment, leaving it for at least 24 hours before proceeding with further work or use. Additionally, it is recommended to apply a protective waterproof coating to the marble’s surface for added protection.

5. Regular Maintenance and Care

Even after taking all necessary preventive measures during installation, regular maintenance is crucial. Periodically check the stone surface and reapply protective products as needed to extend the life of the marble and maintain its original beauty.

Conclusion

By scientifically using Hanshi 919 Stone Interface Back Glue Sealant and Hanshi 130 Anti-Efflorescence Additive, you can effectively prevent yellowing when installing white marble. These products will help you overcome common installation challenges, ensuring the long-term beauty and durability of the marble. By following the above steps, your white marble will remain as pristine as the day it was installed, radiating its unique elegant charm.
