Why is joint stabilizing sealer better than polymeric sand?
Polymeric sand and joint stabilizing sealers both bond sand to keep it in place. The difference is that the chemical polymers in polymeric sand soften each time they become wet, then harden again as the sand dries out. This cycle reduces the effectiveness and lifespan of the polymeric sand, generally to less than two years. The chemical formulas of Surebond sealers do not react this way and maintain bond integrity consistently from initial cure. Additionally, polymeric sand does not offer any stain protection or aesthetic enhancement to the pavement surface.
