What does it mean when sand is polymeric?
If there is a crust forming on the surface of the sand, typically this means that the sand was filled too high or the sand was not watered enough. If the sand was filled too high in the initial installation, the sand will continuously be worn and eroded away.
Why is my sand not setting?
Typically this occurs because there was a rainfall shortly after the installation which caused the sand not to set, the sand was watered for too long, or there is not proper drainage in the base. If the problem is caused by the base, then there is a bigger problem at hand.
How far should you sweep polymeric sand?
Most manufacturers recommend not to sweep the sand more than 10 feet in any direction to avoid separating the delicate formula.

Of course, when applied properly though, sealer can create a beautiful finish to your polymeric sand project.
Can you put pavers over concrete?
Pavers or stone should be set on crushed concrete, limestone, aggregate, etc, with bedding sand in between. In some cases, thin pavers can be installed over concrete, typically with bedding sand in between to provide a cushion effect and drainage. Installation guidelines vary throughout the country to account for varying soil limitations and climate conditions, as well as usage requirements (vehicular versus pedestrian). If polymeric sand is used in areas without proper drainage, then the water will expose the sand to prolonged periods of wetness and moisture, making it vulnerable to washout. In order for the polymers to harden, the water has to be able to escape.
