Sealant should be installed when joint is at midrange <br />of its anticipated movement <br />Cure Time Final cure: 5–7 days <br />Tack Free Time 3–6 hours <br />APPLICATION INSTRUCTIONS <br />SUBSTRATE PREPARATION <br />Clean all surfaces. Cracks/Joints must be sound, clean, <br />dry, frost-free, and free of oil and grease. Curing <br />compound residues and any other foreign matter must <br />be thoroughly removed. <br />APPLICATION METHOD / TOOLS <br />Recommended application temperatures: 40 to 100 °F (4 <br />to 38 °C). For cold weather application, condition units <br />at approximately 70 °F (21 °C); remove prior to using. <br />For best performance, Sikaflex® Concrete Fix should be <br />gunned into joint when joint slot is at mid-point of its <br />designed expansion and contraction. Place nozzle of gun <br />into bottom of the joint and fill entire joint. Keep the <br />nozzle in the sealant, continue on with a steady flow of <br />sealant preceding the nozzle to avoid air entrapment. <br />Avoid overlapping of sealant to eliminate entrapment of <br />air. Tool as required. Maximum sealant depth is 1/2 in. <br />(12.7 mm) and width is 1 in. (25.4 mm). Minimum depth <br />is 1/4 (6.3 mm) and width is 1/4 in. (6.3 mm). Proper <br />design is 2:1 width to depth ratio. For use in horizontal <br />joints in traffic areas, the absolute minimum depth of <br />the sealant is 1/2 in. (12.7 mm). Always use bond <br />breaker tape or closed cell backer rod for support on <br />horizontal joints. Tool as necessary, with dry sealant <br />spatula. <br /> <br />Uncured material can be removed with approved <br />solvent. Cured material can only be removed <br />mechanically. For spillage, collect, absorb, and dispose <br />of in accordance with current, applicable local, state, <br />and federal regulations. <br />LIMITATIONS <br />Allow 1-week cure at standard conditions when using <br />Sikaflex® Concrete Fix in total water immersion and <br />prior to painting. <br />▪ <br />When overcoating with water-based, oil-based or <br />rubber-based paints, compatibility and adhesion <br />testing of mock-up installations is essential. <br />▪ <br />Avoid exposure to high levels of chlorine. (Maximum <br />continuous level is 5ppm of chlorine.) <br />▪ <br />Maximum depth of sealant must not exceed 1/2 in. <br />(12.7 mm); minimum depth is 1/4 in. (6.35 mm). <br />▪ <br />Maximum width of sealant must not exceed 1 in.
