GE’s Advanced Silicone 2 Kitchen & Bath sealant in the 2.8 oz clear squeeze tube delivers 30-minute water-ready performance with 5X stronger adhesion than standard silicone formulas. The neutral-cure formula won’t damage high-end chrome, bronze, or nickel finishes — a critical feature when working with today’s premium faucets and fixtures.
This 100% silicone sealant offers 40% more flexibility than Class 25 sealants, handling Montana’s extreme temperature swings without cracking or pulling away from surfaces. The sealant meets ASTM C-920 Class 35 standards with 35% joint movement capability, making it suitable for applications where materials expand and contract significantly through seasonal changes.
Performance That Matters to Contractors
The standout feature is the 30-minute water-ready time versus 24 hours for standard silicone. Contractors can finish a bathroom install and have it functional the same day. Full cure happens in 24 hours, though surface hardening starts in 30-60 minutes.
The formula provides 5X stronger adhesion than GE’s Silicone 1 sealant — measurable performance that reduces callbacks. The neutral cure formula produces low odor during application, essential for winter work when ventilation is limited.

Real-World Applications and Compatibility
The product works with ceramic and porcelain tile, glass, metals (chrome, bronze, nickel, aluminum), plastics, woods, drywall and plaster, granite and cultured marble, and natural stone. The neutral cure formula ensures it won’t blemish high-end finishes.
Installation follows standard silicone procedure: clean surface to remove dirt, grease, and old sealant. Ensure area is dry. Cut the nozzle at a 45-degree angle, pierce the inner foil seal, squeeze tube to apply sealant into the gap, smooth the bead immediately, then allow 30 minutes before water exposure.
Common applications include kitchen sinks and countertops, bathroom tubs and showers, backsplashes and tiles, plumbing fixtures, and general sealing in high-moisture areas.
Customer Feedback and Long-Term Performance
With 4.6 stars from 5,177 reviews, contractors appreciate the performance. Users praise the quick drying time, easy application with the squeeze tube, strong waterproof seal, low odor, and professional-looking clear finish.
The main complaints involve the tube becoming difficult to squeeze when nearly empty and mixed results on long-term adhesion for some specific plastics. The non-paintable nature requires careful application — once it’s down, it’s permanent.
GE backs this sealant with a lifetime guarantee for as long as the consumer owns their home. The 10-year mold-free product protection reduces warranty callbacks for kitchen and bath installations.
Montana Considerations
The 30-minute water-ready time matters during Montana’s short construction season when delays cost money. The 40% extra flexibility compared to Class 25 sealants handles temperature cycling from -30°F winters to 90°F summers without cracking.
The low-odor neutral cure formula works well for winter indoor projects when opening windows isn’t an option. The compatibility with high-end metal finishes prevents damage to expensive fixtures that are increasingly common in Whitefish and Big Sky builds.
Frequently Asked Questions
Q: How does this compare to GE Supreme Silicone?
Supreme offers lifetime mold protection and 50% joint movement (Class 50), whereas Advanced Silicone 2 offers 10-year protection and 35-40% flexibility. Supreme costs more but delivers superior specs for demanding applications.
Q: Can I paint over this sealant?
No, this is a non-paintable formula. Choose your color carefully or mask precisely during application.
Q: Will it damage my oil-rubbed bronze faucet?
No, the neutral cure formula won’t blemish chrome, bronze, or nickel finishes. This is a key advantage over acidic-cure silicones.
Q: How much coverage does the 2.8 oz tube provide?
Coverage varies significantly based on bead size and joint dimensions. A standard 1/4-inch bead typically runs 12-16 feet per 2.8 oz tube, but deeper joints or wider beads reduce linear footage proportionally.
Q: Is it suitable for exterior use?
Yes, it’s 100% waterproof and weatherproof, though designed primarily for kitchen sinks and countertops, bathroom tubs and showers, backsplashes and tiles, and plumbing fixtures.
