  • PRODUCT HIGHLIGHTS
  • APPLICATIONS
  • HOW TO APPLY
• No tooling, less labor • Extremely long service life • Ideal for cold climates • Excellent flexibility for extreme high and low temperature conditions • Excellent flexibility for dynamic joint movement • Bonds to most substrates without priming including asphalt and concrete • Ready to use, labor cost reduction • More productivity • All season ease of application • Good contact/adhesion with hard to reach areas • Excellent for use on runways and tarmacs • Jet fuel resistant • Resistant to road salts
Ready to use, apply using professional caulking gun or dispensing equipment. Do not open product container until preparation work has been completed. Apply sealant using consistent, positive pressure to force sealant into the joint. Apply the sealant so that it is recessed 1/8 inch (3 mm) below the surface. For parking deck joints, recess 1/4 inch (6 mm). For highway joints, recess 1/2 inch (13 mm). Sikasil-728 SL is selfleveling therefore, no tooling is needed. Sikasil-728 SL will obtain adhesion to aged, cured asphalt. Never use on newly poured asphalt. Conduct a field test to document and confirm adhesion under actual jobsite conditions.
The substrate must be clean, dry, frost free, sound and free of any oils, greases or incompatible sealers, paints or coatings that may interfere with adhesion.
