Surface Preparation

Cracks must be cleaned of dust, dirt, debris, and vegetation. Deep cracks may be filled with sand or foam backer rod to within 3/4″ below the surface prior to placement of CourtFlex.

Mixing Procedures



Use product as is. Do not dilute. Pour into crack until it is filled completely. Set time is dependent upon temperature, humidity and sealer thickness. For best results, apply on dry surface when surface temperature is not expected to drop below 50 °F or exceed 120°F. Material must be at or below surface level when application is completed. Before material sets up, scrape excess from surface and use a rubber squeegee (rounded or V-shaped preferably), to assure below surface contour of finished application.


Temperatures must be above 50 ºF both during application and for a period of 24 hours after application.

Drying Time

Drying time can vary depending upon temperature, humidity, and filler thickness.

Clean Up

Wash tools in water before material dries.
