* 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.




Maintenance of paved surface 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.
Moss
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.
The quantity required depends on the size of the joints. One pail of 40 lb (18.1 kg) will cover: (see graphic below)

- GATOR NITRO JOINT SAND is an extremely strong and rigid jointing material, please ensure there is ABSOLUTELY NO paver or stone movement prior to installation to prevent joint cracking.
- For Pedestrian Use Only, not for Vehicular Applications
- GATOR NITRO JOINT SAND must be installed above 37°F (3°C).
- Joint Width: Minimum 3/16″ (5 mm) Maximum 2″ (50 mm)
- Joint Depth: Minimum 1″ (25 mm) Maximum 6″ (15 cm)
- Working Time: Approximately 45 minutes.
- GATOR NITRO JOINT SAND can only be used on a drainage base application. In a non-drainage base application, GATOR NITRO JOINT SAND cannot be used.
- Paved surface can be used after 18 hours.
- Avoid power-washing for a minimum of 28 days after applying.
REQUIRED SUB-SURFACE PREPARATION AND FOUNDATION OPTIONS
Option 1 Traditional:
- Gator Fabric GF4.4 covering bottom and side of excavated area
- Compacted crushed stone 0-3/4″ ( 0-20 mm) with Sand or Chip Setting Bed (ASTM No. 9)
- Remove bedding layer, install Gator Edge against the paved selected surface and nailed on the compacted crushed stone
Option 2 Open graded / Permeable:
- Gator Fabric GF4.4 covering bottom and side of excavated area
- Clean Stone Base 3/4″ (20 mm) with Chip Setting Bed (ASTM No. 9)
- Remove bedding layer, spread and trowel Gator XTreme Edge
N.B. GATOR NITRO JOINT SAND could be installed only 90 minutes after Gator XTreme Edge has been applied
Option 3 Gator Base:
- Gator Fabric GF4.4 covering bottom and side of excavated area
- Installation of Sand or Chip Setting Bed (ASTM No. 9)
- Gator Base installation exceeding 6″ (15 cm) the final paved area
- Install Gator Edge against the paved selected surface and use Gator Base Screws on the Gator Base
Installation Instructions
Designed for pedestrian use only, GATOR NITRO JOINT SAND is ready-to-use and does not require any mixing. After you have followed the REQUIRED SUB-SURFACE PREPARATION described above, you are ready to apply the GATOR NITRO JOINT SAND. Installation will be easier with two people.
NOTE
- There is no need to protect treated joints from rain while setting. Although the presence of rain will delay the setting process. Full strength: 28 days but surface can be walked on after 18 hours. If heavy rain has occurred when the joints have been pointed, then it may be necessary to revisit the job once the weather has cleared to touch up joints.
- GATOR NITRO JOINT SAND can be applied when pavers, Wet cast or natural stones are installed directly on open graded aggregates that lock or choke themselves. This means the GATOR NITRO JOINT SAND will not migrate through the voids. Do not apply GATOR NITRO JOINT SAND when the pavers, Wet cast or natural stones are installed directly on aggregates with large voids.
- GATOR NITRO JOINT SAND becomes very firm but will detach from pavers, Wet cast or natural stones if the sub-base has excessive movement. It will also detach or crack from the pavers, Wet cast or natural stones, if they are oscillating back and forth due to improper sub-surface preparation. By following GATOR NITRO JOINT SAND installation instructions carefully, you will obtain a very hard jointing material. It should be noted that GATOR NITRO JOINT SAND will continue to harden over time. When installing pavers, wet cast or natural stones around an underground pool, a slope of 1/8 inch (3 mm) per linear foot (30 cm) away from the pool is mandatory. All pavers, wet cast or natural stone surfaces must have a drainage slope for the GATOR NITRO JOINT SAND to work at its optimum. For the pool coping blocks, it is mandatory to use mortar in the joints. For the rest of the pavers, wet cast or natural stones installation around the pool, you can use GATOR NITRO JOINT SAND.
