  • PRODUCT HIGHLIGHTS
  • APPLICATIONS
  • HOW TO APPLY
• Tough, elastic, rubber-like seal • Remains flexible with expansion and contraction of building component without adhesive or cohesive failure, under suitable design conditions • Stays resilient within a wide temperature range • Excellent resistance to water, oils, grease, most solvents, mild acids and alkalis
All joint surfaces must be clean, sound, dry and frost-free. Joint walls must be free of oils, 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.
Apply sealant only to clean, sound, dry, and frost-free substrates. Sika® Duoflex® NS/SL should be applied into joints when joint slot is at mid-point of its designed expansion and contraction. To place, load directly into bulk gun or use a follower plate loading system. 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.
