    APPLICATION PROCEDURES: PREPARATION: Cracks and joints should be clean and dry. Any contaminants including paints, curing compounds, oil, dirt and debris must be removed prior to application. Condition this material to 65°F - 85°F before using.

    APPLICATION: Cartridge Application - Shake the cartridge and remove the nut and cartridge plugs. Attach static mixer to cartridge and replace the nut. Install cartridge into mix gun, place mixer tip into the area to be filled and squeeze the trigger to begin product flow. Maintain steady pressure to ensure proper mixing.  When used on industrial floors with heavy load transfers, it is recommended to fill to the full depth of the crack or joint. NOTE: Silica sand may be used to discontinue flow into cracks and joints. 

    • This product is available in gallons, or in a Dual Cartridge caulk tube, that requires a special dual-cartridge caulking gun (such as sold here on Amazon).  Cartridges are 600-ml (approx. 20-fl. oz. each).

    DRY TIME*: At 70°F, this product gels in 2-4 minutes and is tack free in 30 minutes. *Gel times, cure times and thin film tack free times will be extended with cooler temperatures.

    CLEAN UP: Spills of uncured material may be cleaned with XYLENE. Cured material is extremely chemically inert and should be scraped off surfaces before it cures. Discard any used static mixers and do not attempt to reuse.
