GATOR NITRO JOINT SAND is the ideal air cure, permeable jointing material. It is a ready-to-use mixture of calibrated sand and proprietary resin formula which cures when exposed to air, hardening from top to bottom of the joint. The product can be installed in wet or dry weather.
 
Full strength will be reached after 28 days. 
The surface can be opened to traffic after initial setting, approximately 18 hours in dry conditions above 75°F(24°C). 
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.
