Sand is a naturally abrasive material. It’s often used for traction on slick surfaces, and it’s sometimes used in industrial cleaning. Adding sand to concrete creates a new texture that can be used to increase the traction on the surface. Adding aggregates, such as sand, you can also change the way that concrete reacts to extreme weather patterns.
The addition of different sands and other aggregates can also change the color, texture, and properties of the concrete surface. You can add bits of colored glass and create a decorative canvas, or you can add different colored sands that make for new patterns.
The addition of an aggregate can also alter the consistency of the concrete, making it easier to manipulate for decorative sculpting. You can stamp patterns, or sculpt details into mixed aggregate concrete much easier than straight or poured slab concrete.
Micro-Toppings are typically applied in a very thin layer. This allows them more flex than a thick or dense layer of concrete. The coarseness of the grit will depend on the intended purpose and the request of the customer.
