Polymeric Sand vs. Stone Dust: Which to Choose?

74 On the other hand, stone dust contains no such binders and does not harden. That dust does not adhere to itself or anything else. 4. Weed Resistance The next big difference here is that because polymeric sand hardens, it forms a rockhard layer that weeds cannot grow through.

Dealing With Floor Dust: The Best Way to Stop Concrete

831 Durability Issues From a purely practical point of view, floor dust is bad for the durability of your flooring. Concrete losing its top layer raises a variety of issues. Sweeping this dust away with a heavyduty broom can scratch or damage the concrete beneath. The more floor dust you see, the more erosion is taking place.
