Comments about Sika Sikaflex 1C SL 1-part Polyurethane Sealant:
BEST concrete sidewalk filler I have ever used - have used 4 differetn products. Exceeds label expectations and claims. I even used it on asphalt driveway cracks that had previouly been filled by aspahlt filler for 5 years that have not done the job.
Waaaaay too easy to use. Hardest part is puncturing the seal. Neighbors and church want me to fill their cracks.
