SUBSTRATE QUALITY
Joint wall surfaces must be clean, structurally sound, and frost-free. Joint walls must be free of oils, grease, curing compound residues, and any other foreign matter that might prevent bond.
SUBSTRATE PREPARATION
Substrate preparation should be accomplished preferably by mechanical means. All surfaces must be clean before Sikaflex® Self Leveling Sealant application. Bond breaker tape or backer rod must be used in bottom of joint to prevent three-sided bond. Proper design is 2:1 width to depth ratio.
Note: Priming is not usually necessary. Substrates only require priming if testing indicates a need. Consult Sikaflex® Primer Product Data Sheet or Contact Sika Canada Technical Service for additional information on priming.
CLEAN UP
Uncured material can be removed from equipment and tools using Sika® Cleaning Wipes or a solvent, such as xylene. Strictly follow solvent manufacturer’s warnings and instructions for use. Cured material can only be removed manually or mechanically.
