Compact Polymeric Sand into Paver Joints

What happens here
Before beginning this step, ensure that your paver patio is completely dry, as moisture can prematurely activate the polymeric sand. First, spread polymeric sand evenly over the entire paver surface. Use a stiff-bristled broom to thoroughly sweep the sand into all the joints between the pavers, ensuring they are adequately filled. Once the joints are filled, it is critical to remove any excess sand from the paver surfaces using the broom or a leaf blower. Leaving excess sand on the paver tops before compaction and activation can result in a permanent haze or film on the pavers, which is difficult to remove. After the sand is swept into the joints and the paver surfaces are clean, operate a plate compactor, often referred to colloquially as a "sand rattler," over the paver surface. The compactor's vibrations cause the polymeric sand to settle deeply and compactly into the paver joints. Move the compactor slowly and systematically across the entire patio area, making multiple passes. It's recommended to make passes in at least two different directions (e.g., perpendicular passes) to ensure optimal compaction and complete filling of all joints. This process is vital as it locks the pavers in place, creating a stable and durable surface, and significantly reduces the potential for future weed growth and insect infestation. After the initial compaction, visually inspect the sand levels in the joints; if they have settled significantly, add more polymeric sand, sweep it into the gaps, and repeat the compaction process until all joints are uniformly filled and stable.
Goal: Achieve stable and filled paver joints
