Activate and Cure Polymeric Sand

What happens here
Using a garden hose equipped with a gentle spray nozzle, begin to lightly mist the entire paver surface. The goal is to slowly wet the polymeric sand until it is fully saturated, and water is absorbed without washing the sand out of the joints. Continue this process carefully, moving across the entire area, until you see water begin to slightly pool on the surface of the joints for about a minute. The narrator explains that when wet, this polymeric sand 'bonds' and 'is not going to move'. This activation causes the polymers within the sand to bond and harden, effectively locking the pavers in place. Allow the sand to cure completely according to the manufacturer's instructions, typically 24-48 hours, during which time the area should remain dry and undisturbed to ensure proper bonding.
Goal: Activate polymers to bond and harden the sand.
