Suitable for use to fill and repair concrete bridge decks and concrete slabs.
As supplied, each 600-ml cartridge will fill 36 cubic inches (or a crack that is 12 linear feet long, by 1/8” wide, by 2” deep). On bridge decks, each 600-ml cartridge will cover approximately 75-100 linear feet. As supplied, each 2-gallon kit will fill 462 cubic inches.
At 70°F, this product gels in 3-6 minutes and is tack free in 10 minutes. *Gel times, cure times and thin film tack free times will be extended with cooler temperatures.
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.
APPLICATION: TK-9030 Cartridge Application - Shake the cartridge and remove the nut and cartridge plugs. Install flow restrictor, 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.
Bulk Kit Application - When using either 2-gallon or 10-gallon bulk kits: Stir parts A and B separately before combining together. Mix equal parts A and B by volume. Blend quickly and vigorously using a paddle-type mixer until the material is completely homogeneous. Scrape the sides of container frequently while mixing. Mix only small amounts at one time and work quickly as pot life of catalyzed material is 3-6 minutes at 75°F (24°C).
NOTE: Silica sand may be used to discontinue flow into cracks and joints
