Water Activate Polymeric Sand

What happens here

Using a garden hose fitted with a fine spray nozzle, gently and evenly mist the entire sanded area. Do not flood the area; a light, even spray is sufficient to activate the polymers within the sand. The video shows a bubbling effect as the water mixes with the sand, indicating activation. Apply water in several light passes, allowing 15-20 minutes between each pass, rather than one heavy soak to ensure deep penetration and activation without washing sand out of the joints.

Goal: Harden the polymeric sand to lock pavers in place
