Selection Of Stone Protective Agent

1. Select according to the protection requirements:

If the purpose of protection is to prevent alkali pan and rust, silicone stone protective agent can be used to achieve the effect.

If the purpose of protection is to integrate waterproof and antifouling capacity, organic fluorine stone protective agent is generally used to achieve the effect.

2. Select according to the stone installation environment:

If it is used for outdoor stone protection, it is recommended to select oily stone protective agent for treatment. Because the anti-aging ability of the oil protective agent is stronger than that of water, the service life is longer.

For indoor stone protection, in addition to oil-based protective agent, water-based stone protective agent can also be selected for surface treatment. Because the indoor environment is less affected, the impact on the service life of the product is relatively small. The cheap water-based protective agent is naturally loved by many customers.

3. According to the installation process of stone:

It is recommended to use hb-g713 for two times of front and side protection for wet pasted and grouted stones and general granite (tested by the national authority). If you are not at ease, you can use hb-g633 for bottom protection. The selection of bottom protective agent shall pay attention to the alkali resistance of protective agent, and shall not affect the bonding fastness between stone and cement. Hb-g118, g168, g700, G710, g711 and g713 can be selected for marble wet paste. Hb-g700 and g168 can be selected for sandstone surface, and then hb-g633 and g733 can be used for waterproof and alkali proof treatment on the bottom.

Dry hanging stone is adopted. The standard for selecting stone protective agent mainly focuses on water resistance. Hb-g118, g168, G710, g711, g713 and other products can be selected.

4. If it is a stone with dense structure, such as Spanish beige, slate, etc., it is recommended to use oily stone protective agent. Because the solvent component has strong permeability, it can go deeper into the interior of the stone for protection. However, it should be noted that for the black stone with dense structure, the general protective agent will deepen the color of the stone, which should be handled carefully; For stones with general structure, oily and water-based stone protective agents can be selected.

5. If it is a restaurant, stove, driveway or other places prone to pollution, it is recommended to use organic fluorine stone protective agent on the surface to improve the anti pollution ability of the stone surface.

6. For stones in squares, aisles and public places, hb-g713 oil permeable king is recommended to be used for 2 ~ 3 times of protective treatment on the surface and side. Because G713 has super penetration ability, and its acid resistance, alkali resistance and aging resistance are over one times the national superior standard. The quality is excellent. In case of stones on the ground of subway station and underground floor, hb-g733 stone bottom surface shall be used for treatment on the bottom surface in addition to hb-g713 on the surface and side.

7. At present, many customers like to make membrane curing treatment on the surface of rough stone. For this project, it is recommended to use membrane-forming stone protective agent with silicone as raw material. This product has good hardness, high bonding strength, UV resistance and is not easy to turn yellow; Do not easily use the bottom sealant with acrylic acid as raw material. This product is mainly designed for bottom sealing. Peeling and discoloration often occur on the stone surface.
