How to distinguish the quality of liquid marble surface?

Many friends are asking how to distinguish between good and bad natural marble liquid coffee tables, as well as the reasons for price differences. Although I want to post a few water wave surface pictures of other people's homes for comparison, I feel that it's a bit unfriendly, so I won't take the pictures. You can search for water wave surface marble by yourself to see the differences in craftsmanship and aesthetics.
• It's not about chiseling out potholes and then polishing them, it's just a rippling surface
1. The visual sensation of liquid flow must be natural;
2️. The excessive treatment at the junction of liquid and flat surfaces must not be too hard (I have seen transitions that are unnatural, hard, and devoid of aesthetic appeal).

Teach you how to choose high-quality marble stone?

New house decoration, many users like to use marble, so how much do you know about marble? How to choose high-quality marble stone? So as to avoid pitfalls, let's explore the selection strategy for marble together today.

Let's first understand the grades of marble, which are generally divided into three grades: superior, first-class, and qualified. This grade is determined through the testing and identification of instruments and measuring tools, and generally manufacturers will issue a stone grade certificate. When selecting physical stores, the following methods can be used to determine the quality of stone materials.

Firstly, look at the surface gloss. The brighter the surface, the harder the texture. Stones are arranged according to color schemes and types, and when selecting, the overall texture should be considered. The finer the texture particles, the better the quality. Carefully observe its surface gloss. After polishing, the surface of marble is smooth like a mirror, and the brighter the mirror effect, the harder the stone, the higher the structural density, and the better the quality.

Additionally, you can use the tapping method to strike the marble, and the clearer the sound, the better. We can use coins or other items to strike the stone, which can produce a crisp sound, indicating that the stone has high hardness and good quality. If the sound is dull, it indicates that the stone has low hardness or internal cracks, and the quality is relatively poor. It is not recommended to choose.

The next step is to confirm the integrity of the stone, first checking the surface for cracks or bumps. After all, marble is naturally generated and its integrity is difficult to determine. Surface defects are inevitable, and a few holes are acceptable. These defects can be repaired by polishing and filling. The most important thing is to observe whether there are cracks or bumps on the surface of the marble. Although marble has high hardness, it is relatively brittle. In the event of cracks, it is not recommended to purchase and reprocess it. During the processing, larger cracks may occur, and even the entire piece may break. This is not worth the loss.

How to judge the quality of marble

To determine the quality of marble, comprehensive surface observation, physical testing, water absorption detection, and grade differentiation are required. The core methods include observing texture and luster, tapping and listening, ink drop testing, and referencing grade standards to ensure the selection of dense, hard, and aesthetically pleasing high-quality stone. ‌‌
Surface observation and texture inspection
Gloss and texture: High quality marble has a mirror like reflection after polishing, and the brighter the surface, the harder and denser the stone; The fine and uniform texture of the particles indicates superior quality, and it is recommended to avoid selecting boards with obvious fractures or large areas of impact damage. ‌‌
Color and integrity: The color should be natural and comfortable (such as a beige base that is more resistant to fading), without any plastic or cloudy feeling; Small pores or air holes on the back may indicate internal looseness, and samples with dense structures should be preferred. ‌‌
 

A Comprehensive Guide to Common Problems, Prevention, and Repair of Marble

To prevent cracks in marble, we need to pay attention to the following points: firstly, avoid heavy objects hitting or scratching the surface of marble; Secondly, during the installation process, ensure the flatness of the foundation ground to reduce stress concentration; Furthermore, regular professional maintenance and the use of protective agents specifically designed for marble can enhance its resistance to dirt and wear; Finally, maintain appropriate indoor humidity to avoid cracking of marble due to dryness. Following these preventive measures can effectively extend the service life of marble, maintaining its beauty and durability.

During transportation, earthquake prevention measures must be taken to prevent the marble from breaking due to vibration.
Before entering the site, it is necessary to carefully inspect the marble to ensure that there are no signs of breakage.
The preparation work before construction is crucial:
(1) Before laying marble, the base layer should be carefully inspected to ensure that there are no issues such as hollowing or cracking.
(2) By taking preventive measures in advance, the risk of marble being exposed to moisture and harmful contamination can be reduced, and defective areas can be prevented from being soaked, contaminated, and damaged.
(3) When laying stone, special attention should be paid to the structural line of marble. Due to its loose texture and low density, this structural line is more prone to moisture absorption, which may lead to problems such as halogen reflux, peeling, and corner collapse. Therefore, in the process of hammering and leveling, it is necessary to control the technique and force.
(4) When applying adhesive to marble, it is usually necessary to evenly coat the five sides (back and side) except for the front. If stone needs to be cut for other reasons, additional adhesive should be applied to the cutting area, while the surface layer should be coated with anti-seepage treatment agent normally.
The flatness of the base surface is crucial when laying long strips of marble. If it is necessary to enhance the strength of marble, the method of backing reinforcement bars can be considered.

How to solve the problem of water seepage in marble window sills

1、 Reasons for water seepage issues
1. External water source. Water leakage from the exterior walls and roofs of buildings seeps into the window sills.

2. Internal drainage system issues with the window sill. Blockage of drainage pipes and unreasonable design of drainage systems result in water being unable to be discharged.

3. Cement base layer issues. Improper treatment of cement base before installation of marble window sills, or damage to cement base, resulting in water seepage.

2、 Handling method
1. Block external water sources. Inspect potential water sources such as exterior walls and roofs, and promptly repair them.

2. Clean the window sill drainage system. Clean the drainage pipes and keep them unobstructed. If the drainage system design is unreasonable, consider redesigning it.

3. Address the issue of the base layer of the window sill. Remove the marble tiles on the surface of the window sill, inspect the cement base, and repair or re lay it.

4. Add waterproofing agent. Spray waterproof agent on the surface of the marble window sill to prevent moisture from seeping into the window sill.

3、 Daily maintenance
1. Regularly inspect the surface of the window sill and promptly address any water seepage issues.

2. Keep the windowsill clean and promptly clean up any accumulated water on the windowsill.

3. Avoid splashing acidic or alkaline liquids onto the windowsill to prevent corrosion of the windowsill surface.

In summary, the solution to the problem of water seepage in marble window sills needs to be approached from multiple perspectives, especially the correct handling of cement base and window sill drainage system issues. At the same time, regular maintenance is also an important means to avoid water seepage problems.
