What is Stone Dust? Dust, also known as grit, quarry dust, quarry screening, and decomposed granite, is one of the most commonly used stone byproducts. It is a looser, darker version of sand that is processed through a crushing machine, which in turn produces crushed stone. The machine's screen traps the larger pieces of crushed …

8. Add Stone Dust. After laying the pavers, the final phase is sprinkling stone dust over the pavers and sweeping it into the crevices. Using fine sand instead of coarse sand makes sense since it easily compacts and fills up the joints faster. Better yet, the stone dust acts as an extra layer of protection against weeds.
