1. All joint surfaces must be clean, sound, free of contaminants, dust free, dry and frost free. Interior joint contact surfaces must be free of previous joint sealing materials, oils, grease, loose tar, paints, coatings, sealers, curing compound residues, rust and any other foreign matter that might prevent good adhesion.
   • Asphalt substrates should be prepared to clean, sound, dust free, dry, and frost free conditions.
   • Concrete substrate preparation should be accomplished by mechanical means (e.g. sandblasting, abrasive grinding, etc.).
2. Mask off and protect any adjacent surfaces (e.g. edges of joint) that should not receive contact with Sikaflex®-411 Hybrid Self-leveling Sealant.
3. Closed cell backer rod or bond breaker tape must be installed at the bottom or base of a dynamically working joint prior to sealant installation to prevent three sided adhesion.
   • Closed cell backer rod diameter should be larger (i.e. typically up to 25% larger) than the actual width of the joint to provide a friction fit and adequate sealant support. Bond breaker tape, when used in lieu of closed cell backer rod, should cover the bottom or base of the joint void.
4. Joint Design: Proper joint design for working joints is 2:1 width to depth ratio (typical), with a recommended minimum 1/4 inch (6 mm) and maximum 1/2 inch (13 mm) depth of sealant.
   • For nonmoving joints, the width to depth ratio can vary.
   • For traffic bearing joints, the maximum recommended 1/2 inch (13 mm) depth of thickness should be considered over appropriate closed cell backer rod or bond breaker tape. Consult with Sika Technical Services for unusual joint configurations.  

Recommended application (i.e. ambient and substrate) temperatures: 50 to 100 °F (10 to 38 °C). Condition sealant cartridge to 65 to 75 °F (18 to 24 °C) before using.

1. Cut the plastic tip at an angle to the desired size and puncture the airtight seal within, at the base of the tip. NOT FOR SLOPED SURFACES.
   • The maximum sealant depth is 1/2 in. (13 mm) and width is 1 inch (25 mm).
   • The minimum sealant depth is 1/4 in. (6 mm) and width is 1/4 in. (6 mm).
2. Dispense sealant into the joint slot over either closed cell backer rod or bond breaker tape in one direction and allow the sealant to flow and level out as necessary.
3. Tool as required, although minimum tooling is necessary.

Uncured Sikaflex®-411 Hybrid Self-leveling Sealant can be removed from tools and finished surfaces using an approved solvent (e.g. Acetone, MEK or Xylene). Cured Sikaflex®-411 Hybrid Self-leveling Sealant can only be removed from surfaces mechanically. For spillage, collect, absorb, and dispose of in accordance with current, applicable local, state, and federal regulations. Consult the current Safety Data Sheet for additional information.
