  • PRODUCT HIGHLIGHTS
  • APPLICATIONS
  • HOW TO APPLY
• Capable of ± 35% joint movement • Eliminates time, effort, and equipment for mixing, filling cartridges and cleaning of equipment • High elasticity - Cures to a tough, durable, flexible consistency with exceptional cut and tear resistance • Excellent adhesion - Bonds to most construction materials without primer in most cases • Excellent resistance to aging, weathering • Resists fuel, mineral oils, and dilute minerals, plant and animal fats • Odorless, non-staining, can be painted over with water, oil, and rubber-base paints. Since some paints dry slowly and the surface may remain slightly tacky, a preliminary test is essential
Recommended application temperatures are between 4 to 38°C (39 to 100°F). For cold-weather application, store units at approximately 21°C (70°F) and remove just prior to using. Make sure joint is frost-free. Install with hand or power operated caulking gun. For best performance, Sikaflex® 1a should be gunned into joint when joint slot is at mid-point of its designed expansion and contraction. Cut plastic tip on cartridge to desired joint size. Puncture airtight seal at base of tip. Place nozzle of gun into bottom of joint and fill entire joint. Keeping the nozzle deep in the sealant, continue with a steady flow of sealant preceding nozzle to avoid air entrapment.Also, avoid overlapping of sealant since this also entraps air. Tool as required. Proper joint design for moving joints is 2:1 width to depth ratio, with a recommended 6 mm (1/4 in) minimum and 13 mm (1/2 in) maximum depth of sealant. For non-moving joints, the width to depth ratio can vary.
All joint surfaces must be clean, sound, dry and frost-free. Joint walls must be free of oils, tar, asphalt, bitumen, grease, paints, coatings, sealers, curing compound residues, and any other foreign matter that might prevent adhesion. Ideally this should be accomplished by mechanical means. Bond breaker tape or backer rod must be used in bottom of joint to prevent bond.
