After all the polymeric sand has been swept and tamped into the joints, remove any remaining loose sand from the paver surface using a broom. It's crucial that no sand is left on top of the pavers before the next step. Then, lightly mist the entire patio area with water from a hose, being careful not to wash away the sand from the joints. The water activates the polymers in the sand, causing it to harden and lock the pavers together, creating a durable and weed-resistant surface.
