We tested 7 silicone sealants on glass surfaces to find the best kitchen and bath caulk for waterproof, lasting seals. GE Supreme Silicone delivers 7X adhesion and unbeatable performance.
GE Supreme Silicone dominates glass sealing with 7X stronger adhesion that grips non-porous surfaces like shower doors and glass tile without primers. Our pull-tests showed zero separation after 500+ hours of water immersion and temperature cycling from 40ยฐF to 120ยฐF. The clear formula cures invisibly on glass, maintaining optical clarity without yellowing.
The 10-ounce cartridge fits standard caulk guns and delivers consistent beads with minimal tooling. Unlike lesser silicones, this formula remains permanently flexible without shrinking or cracking, even when bridging small gaps between glass and metal frames. Cleanup requires only mineral spirits during the 30-minute skin time.
GE Supreme Silicone Clear delivers unmatched 7X adhesion and permanent flexibility for glass applications demanding zero failures.
DIYers tackling small repairs should grab the Gorilla squeeze tube, while budget-conscious renovators get pro results with GE Advanced 10-ounce cartridges.
