# 4 - General Electric Ge5020 Concrete And Masonry Silicone Ii Caulk, 10.1-ounce, Light Grey

GE Silicone II* Concrete & Masonry 100% Silicone THREE-HOUR RAIN-READY - Caulk has to have enough time to build adhesion to the surface and cure or dry adequately so it won't wash away when exposed to water. That means if rain is in the forecast, homeowners and pros typically will have to delay or cancel a project when using most caulks. If not, the rain might wash the caulk away and the job will have to be redone. Silicone caulk, such as GE Silicone II* Concrete & Masonry, develops strength and adhesion quickly so it can be exposed to water…


  • 3-hour rain-ready
  • Sun-/freeze-proof
  • Typical uses: Sidewalks, driveways, patios, masonry, steps, foundations (above ground) and tuck/repointing masonry
  • Adheres to: most concrete, granite, brick, slate, ceramic tile, asphalt and wood
  • Why 100% silicone? Unlike acrylic, silicone is permanently: waterproof, flexible, shrink-/crack-proof
