Why pros spec Geocel over the hardware-store aisle

  • ✓ Seals in real conditions. Bonds to damp, oily, and frozen surfaces — the jobsite doesn't wait for perfect weather, and neither does Geocel.
  • ✓ Stays flexible for years. Tripolymer and hybrid chemistry moves with the structure instead of cracking out like silicone or asphalt caulk.
  • ✓ A formula for every substrate. Shingle, membrane, coated steel, fiberglass — each product is engineered for its surface, not "all-purpose."
  • ✓ 50 years of standard-setting. Made in Elkhart, Indiana since 1974. A Sherwin-Williams company.
