Hz info,

In the field of modern architectural decoration, Sand-in-water Coating has become a popular choice for exterior wall decoration due to its combination of natural stone texture and excellent weather resistance. However, with the growth of market demand, product quality has also shown a significant divide. Ranging from low-cost inferior products to high-end high-quality ones, the quality varies greatly, and many consumers are prone to making wrong choices when purchasing. In fact, judging the quality of Sand-in-water Coating is not complicated. As long as you master the following 6 points, you can easily avoid inferior products and select high-quality coatings that meet your needs.

1. Check the Can-opening State: High-quality Coatings Have No Delamination or Precipitation

Can-opening is the first step to judge the basic quality of Sand-in-water Coating. After opening the can of high-quality Sand-in-water Coating, the internal particles should be in a uniformly suspended state. The overall texture is fine without obvious delamination, and there will be no precipitation such as caking at the bottom and floating water on the top. If delamination is found in the coating after opening the can, or if it takes a long time to stir to re-integrate the particles, it indicates that the product has poor dispersion stability. This will easily lead to uneven coating during subsequent construction, and problems such as peeling and fading may occur during long-term use.

2. Test Particle Clarity: Clear Water Test Reveals the Truth

Particle clarity is the core guarantee for the simulation effect of Sand-in-water Coating, which can be judged through a simple clear water test. Prepare a transparent glass, pour half a cup of clear water, take a small amount of coating and put it into the water, then stir gently. The particles of high-quality coating will remain relatively independent in clear water, with clear outlines. There will be no particle dissolution or turbid water. However, the particles of inferior coating are easy to break and disperse, leading to turbid water. After construction, such products are difficult to present the texture of natural stone, and the aesthetics are greatly reduced.

3. Verify Workability: Flexible Operation Without Strict Conditions

High-quality Sand-in-water Coating itself has good workability. A good Sand-in-water Coating has low requirements for the technical proficiency of construction workers and the air pressure of the air compressor. Whether it is operated by experienced masters or newbies, it can maintain a stable spraying effect. It is not easy to have problems such as particles being sprayed broken, sprayed pasty, or uneven coating thickness. On the contrary, if the coating has extremely strict requirements on construction conditions and construction defects occur if you are not careful, it is likely that the product formula is unreasonable, and wall problems may easily occur in the later stage.

4. Simulation Effect: It’s Hard to Distinguish Between Real and Fake Stone

The core advantage of Sand-in-water Coating lies in replacing dry-hanging stone. Therefore, the simulation effect is a key indicator to judge its quality. The patterns and textures of high-quality Sand-in-water Coating should be highly consistent with the imitated natural stone. When comparing the coating sample with the real stone, it should achieve the effect of "hard to distinguish between real and fake". Not only the overall texture is similar, but also the granularity and color transition in details need to be natural and realistic. If the coating has rigid texture and dull color, which is significantly different from natural stone, even if the price is low, it cannot meet the texture requirements of high-end decoration.

5. Check Water Resistance: Waterproofing is the Foundation

As an exterior wall imitation stone coating, water resistance is an essential performance of Sand-in-water Coating. After curing, high-quality products can form a dense waterproof coating, which can effectively block rainwater penetration. Even if it is in a humid environment for a long time, there will be no problems such as wall moisture regain, mildew, or coating bulging. When purchasing, you can check the water resistance data in the product test report, or conduct a simple test: soak the coating sample in clear water for 24 hours. If the sample has no obvious discoloration or softening, it means the water resistance meets the standard; if blistering or peeling occurs, it is an inferior product.

6. Observe Stability: Still Usable After Long-term Storage

The stability of Sand-in-water Coating directly affects the construction efficiency and project quality. High-quality coatings have extremely strong state stability. Newly produced products do not need to wait for "post-thickening" and can be constructed immediately after opening the can. Moreover, under normal storage conditions, after being placed for 1 day, 1 month or even 1 year, their texture, viscosity and particle state will not change significantly, which can meet the needs of engineering projects with long construction periods and large usage. However, inferior coatings are prone to delamination and caking after being stored for a period of time, and may even be unable to be constructed normally, which will bring great trouble to decoration.

By mastering the above 6 points, you can accurately select high-quality products in the complex Sand-in-water Coating market. Whether it is self-built house decoration or engineering construction, it can ensure that the exterior wall decoration is not only beautiful and durable, but also has no worries.
