- HOW TO APPLY
• Capable of +25% joint movement • Chemical cure allows the sealant to be placed in joints exceeding an inch in depth • Tough, durable, flexible consistency • Exceptional cut and tear resistance • Exceptional adhesion to most substrates without priming • Colour uniformity assured via Color-pak system or pre-pigmented Limestone Gray • Fuel resistant • No colour pak needed in pre-pigmented Limestone Grey •
Recommended application temperatures: 40°-100°F. Pre-conditioned sealant to approximately 70°F is necessary when working at extremes. For best performance, Sikaflex® SelfLeveling Sealant should be poured into joint when joint slot is at mid-point of its designed expansion and contraction. Pour sealant into joint slot in one direction and allow sealant to flow and level out as necessary. Tool as required, although minimum tooling is necessary. Joint dimension should allow for ¼ inch minimum and ½ inch maximum thickness for sealant. Proper design is 2:1 width to depth ratio. Always use bond breaker tape or closed cell backer rod for support on horizontal joints.
All joint-wall surfaces must be clean, sound, and frost-free. Joint walls must be free of oils, grease, curing compound residues, and any other foreign matter that might prevent bond. Ideally, this should be accomplished by mechanical means. A roughened surface will also enhance bond. Bond breaker tape or backer rod must be used in bottom of joint to prevent bond.
