* Gator Nitro Joint Sand will harden from top to bottom up to 2 3/8″ (60 mm). ** Permeable as installed. If not maintained, permeability will be obstructed over time.

When maintaining the paver surface, apply Gator Shampoo to clean the entire paved surface including the paver joints. Wash, rinse and remove any residue by using a hose and a watering gun set to shower with the normal maximum water pressure from any residential or commercial building (typically 80 psi/550 kPa).

GATOR NITRO JOINT SAND is permeable when installed. However, If not maintained properly, permeability will be obstructed over time. To avoid obstruction in the joints, periodically use a pressure washer to remove all dirt and debris. Wait 28 days after the initial application of GATOR NITRO JOINT SAND before using a pressure washer.


GATOR NITRO JOINT SAND will not cause nor prevent moss, mold or mildew. Moss, mold and mildew are caused by certain on-site conditions including excess moisture, shade, absence of ventilation, inadequate cleaning or maintenance, presence of soil or other organic debris left on the product.
