Necessity Whether it is new stone or renovated stone, with normal use over time, the stone will suffer increasing wear and its gloss will decrease progressively. Timeliness Stone must undergo timely maintenance to maintain its desired condition. If the decrease in gloss exceeds the recovery capacity of maintenance measures, it will be impossible to restore the stone to its original gloss level. The correct maintenance method is to promptly adopt maintenance techniques before the decrease in stone gloss exceeds the recovery capacity of maintenance measures. After maintenance, the gloss can basically be restored to its original level, allowing the stone to remain in a like-new state for a long time and maintain an ideal service condition. Due to its naturally formed properties and the fact that it is associated with various compounds, stone is prone to deterioration, weathering, and damage in its surrounding environment—this is caused by internal factors. On the other hand, the deterioration of the service environment, such as acid rain, pollution, and humidity, is also a major factor that causes and accelerates various problems and deterioration of stone. The consequences of these problems and deterioration are severe. From the natural weathering and damage of ancient stone cultural relics to the various natural damages and deterioration of modern building stone, the losses incurred are enormous. Therefore, it has become increasingly important to effectively prevent these damages and deterioration and minimize or control their occurrence. Waxing was once widely used as a method to protect stone, mostly applied to laid stone floors. However, its protective effect on stone is limited: it has poor weather resistance, unsatisfactory stain resistance, and tends to attract dust. Nowadays, people have also found that waxing can cause harm to stone. As a non-breathable sealing material applied to the stone surface, it blocks the stone's pores, preventing moisture inside and behind the stone from evaporating. Prolonged accumulation of moisture inside the stone leads to deterioration. There is also a type of liquid wax often applied to interior walls, which is a film-forming material; its main drawback is that it affects the natural texture of the stone. The emergence of penetrating protective products represents a significant advancement in the development and research of stone protection products, though their application in China has not been very long. Most of these products use solvents or water as carriers to deliver effective waterproofing materials into the stone, forming a deep protective barrier that repels water and some liquid contaminants. In addition to not altering the stone's natural texture, these penetrating protective products also maintain the stone's breathability, offering superior performance and scientific protection. However, due to differences in materials used, some products may vary in waterproofing, stain-resistant, and oil-resistant effects, though most products perform well. When selecting and using stone protection products, in addition to understanding product performance, the following points should be noted: Compatibility: Choose products that do not affect the color of the stone. For wet-paste installation, when treating the back of the stone, test whether it will affect the adhesion between the stone and cement. Wet-paste installation: Ensure proper treatment of the back and sides of the stone; focus on selecting a protective agent with good waterproofing effects. Selection of protective agents for floor stone: In addition to waterproofing the back of the stone, the front surface should also be appropriately protected based on the service environment. For special locations—such as hospitals, choose products with good stain resistance; for hotels, select products with excellent stain and oil resistance. Dry-hung stone: Treating the back of dry-hung stone for protection is of little significance. For the front surface, select appropriate protective products based on the service environment and the stone's characteristics. Stone prone to deterioration: Some gray-white granite and marble often develop rust or yellowing in humid conditions. Prioritize waterproofing treatment and select protective agents with excellent waterproofing effects. Porous and high-absorption granite/marble used in public areas: Must choose products with good waterproof, stain-resistant, and oil-resistant effects to facilitate cleaning in case of contamination.
