Pros

  • Outperforms other seleveling sealants in leveling quality.
  • Achieves a perfectly level, professional finish.
  • Seleveling feature effectively fills low areas.
  • Matches concrete reasonably well with its gray color.
  • Easy to use and effective in sealing cracks.
  • Reduces snow and freeze damage in concrete and brick gaps.
  • Works best when temperatures are above 60°F.

Cons

  • Turns white after a couple of weeks, leading to disappointment.
  • Stays tacky for several days, complicating the application process.
  • Can create porosity issues if bubbling occurs in the joints.
  • Product separation leads to inconsistent color and performance.
  • Difficulties reported in penetrating internal seals in recent purchases.
  • The seleveling feature may not work perfectly across cracks, creating a dome if too much is used.

Bottom Line

Quikrete 8660-10 Advanced Polymer Self-Leveling Sealant is a strong performer when it comes to leveling and achieving a professional finish. However, issues with color stability and tackiness might be a concern for some users. While it may discolor over time, its ability to seal gaps effectively makes it a worthwhile choice for specific projects. We suggest giving it a try, keeping in mind its best performance occurs in warmer conditions and that attention to application techniques will enhance its usability.
