Directions for Use

Area must be clean and dry. Saw-cuts should be blown clean and dry to remove dust and debris. Remove curing and sealing compounds. Stir both A & B components separately before mixing together. Mix thoroughly with a heavy-duty, low speed drill fitted with a mixing paddle. Mix until a uniform gray color appears and no streaks are evident. Apply with bulk caulking gun or pour from can. Fill joints flush to the top or slightly higher than the surrounding surface. To prevent C-JOINT from running through shrinkage cracks at bottom of joint, apply a maximum of ¼” of fine sand. A second pass prior to curing may be necessary due to the fact that all pour grade materials will “dish” or become concave. Remove all tape and clean spills and tools immediately with a suitable solvent such as xylene or lacquer thinner.

Pot Life: 15-25 minutes. 

Initial Cure Time: 6-8 hours. 

Traffic Ready: 8-12 hours.

Dry Time Tack Free: 4-6 hours @ 75°F  

 2 year shelf life.
