  1. Always refer to the latest GATOR NITRO JOINT SAND Technical Data Sheet (TDS) at before installing.
  2. GATOR NITRO JOINT SAND can be installed rain or shine. Paving surface must be pre-wet before installation and must remain wet throughout the installation process or staining may occur.
  3. GATOR NITRO JOINT SAND is an extremely strong and rigid jointing material, please ensure there is ABSOLUTELY NO paver or stone or outdoor porcelain tile movement prior to installation in order to prevent joint cracking.
  4. For pedestrian and vehicular applications.
  5. GATOR NITRO JOINT SAND must be installed above 37°F (3°C).
  6. Working Time: Approximately 45 minutes.
  7. 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.
  8. Paved surface can be used after 18 hours.

GATOR NITRO JOINT SAND is recommended for a variety of uses, including patios, walkways, pool decks and driveways. The pavers, porcelain tiles, natural or wet cast stones must be installed on a drainage base system for pedestrian and light vehicular traffic applications and Gator Base systems for pavers, porcelain tiles, natural or wet cast stones for pedestrian applications only.

Installation Instructions

Designed for pedestrian applications and residential driveways, GATOR NITRO JOINT SAND is ready-to-use and does not require any mixing. After you have followed the REQUIRED SUB-SURFACE PREPARATION described on the right-side panel, you are ready to apply the GATOR NITRO JOINT SAND. Installation will be easier with two people


The joints are effectively rain safe immediately, although rain will delay the setting process. Full strength will be reached after 28 days. Surface can be opened to traffic after initial setting, approximately 18 hours in dry conditions above 75°F. 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, natural or wet cast stones are installed directly on open graded aggregates that lock or choke themselves. For residential vehicular use, GATOR NITRO JOINT SAND must be used with interlocking concrete pavers only. GATOR NITRO JOINT SAND is a solid joint material, however it is not designed to resist the movement that will occur in a vehicular application with non-interlocking pavers and stones, or with certain interlocking paver styles which can move or rotate when subjected to vehicular traffic. Porcelain tile must be installed with the Gator Tile System. Visit our Technical Data Sheet (TDS) at for complete details. GATOR NITRO JOINT SAND becomes very firm but will detach from outdoor porcelain tiles, pavers, natural or wet cast stones if the base has excessive movement. Excessive movement of pavers, tiles or stones may cause GATOR NITRO JOINT SAND to crack or detach. By following GATOR NITRO JOINT SAND’s 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.


Ensure paver surface is compacted, then thoroughly wet the area to be jointed. If the surface is dry or temperature is high, more water will be required to avoid staining of the surface when spreading the GATOR NITRO JOINT SAND.


Open the bags and spread the contents over the paved surface. Wet the GATOR NITRO JOINT SAND with a hose set on “shower” while using a squeegee or broom to push the GATOR NITRO JOINT SAND diagonally across the paved surface and into the joints. This action compacts and forces the GATOR NITRO JOINT SAND into the joints ensuring the gaps are completely filled.


The joints should be filled 1/8″ (3 mm) below the top surface or 1/8″ (3 mm) below the paving stone chamfer with the GATOR NITRO JOINT SAND. Shower the surface to rinse off excess material from the paved surface. Repeat steps 2 and 3 until the whole paving area is completed.


Any excess GATOR NITRO JOINT SAND residue left on the paved surface can by simply cleaned off by brushing and rinsing off the surface. Leftover material can be stored directly in the pail with 2″ (50 mm) of water covering the GATOR NITRO JOINT SAND and closing the pail tightly. Leftover product will last about 4 weeks when stored in this fashion. 

For a nicer, smoother surface joint finish, use a suitable mason jointing tool. This process can only be done once Steps 1 to 4 are completed and the GATOR NITRO JOINT SAND is in its curing phase. Allow approximately 18 hours of cure time before use. Temperature and humidity will impact curing time.
