What's the difference between sand in sand and sand in water?

As the saying goes, "Interlacing is like a mountain". If you don't work in construction, I believe most people have never heard of sand bags and underwater sand, let alone what they are used for. So what's the difference between sand wrapped in sand and sand in water?

1 has different uses. The former is mainly used to imitate granite and other litchi stone materials, while the latter is suitable for different high-end projects.

2, the surface morphology is different. The former is smooth and needs to be used with other supporting products. The latter has a pockmarked surface, and the texture is three-dimensional and layered, and the simulation degree is higher.

3. The performance is different. The former has poor film strength and weak weather resistance. The latter has strong coating strength and outstanding weather resistance, which combines the advantages of real stone paint and sandbag sand and has a wide application range.

4, the process is different. The former uses wrapping technology to wrap and mix pigments of different colors into pigments, and the particles will be separated from each other and suspended in the packaging barrel. The latter is technically difficult and consists of sand, water-based emulsion and a proper amount of colored sand.

The above is an introduction to the difference between sand wrapped in sand and sand in water, hoping to help some friends in need.
