Product review
What’s included: one 10 fluid ounce cartridge of GE Supreme silicone caulk in white.
Material and performance: The formula is pure silicone, formulated to provide a waterproof seal that resists shrinking and cracking as it cures. The manufacturer promotes up to 7× stronger adhesion versus standard caulks and adds mildew-resistant properties to keep seams looking clean longer.
How to use: Cut the cartridge nozzle to the desired bead size, load into a caulk gun, apply along joints at tubs, sinks, counters or tile transitions, then tool or smooth the bead for a neat finish. It cures to a flexible, water-tight joint — water-ready faster than many conventional formulas — and is meant specifically for kitchen and bathroom environments where moisture and movement occur.
Pros
- Highly waterproof, suitable for wet areas
- Strong adhesion and flexible after curing
- Mildew-resistant white finish
Cons
- Quite viscous — tougher to dispense
- Factory nozzle can be wide for tight gaps
- Sold as a single cartridge
VerdictReliable and highly water-resistant, this 10 fl oz silicone cartridge provides a durable, flexible seal for wet areas. It adheres strongly, resists shrinkage and mildew, and finishes cleanly in white. Expect a thicker feel when dispensing and consider trimming the tip for tight joints.

Quick to water-ready but thick to squeeze
Chose this for its faster water-ready time — handy with a busy household. It does set quicker than many brands. Downside: very viscous and harder to push out of the gun, though it performs well once laid.

Mold fighter for problem bathrooms
Great for tubs and sinks. Easy to apply and after about four months there’s no sign of mold in our trouble spot. Worth the purchase.

Excellent caulk for tubs and showers
So far this is the most reliable tub/shower caulk I’ve used. I had a problematic shower that mildew’d easily; this time the application went on smoothly and stayed clean.

Effective for resealing shower pans
Resealed my shower pan with it. Went on nicely and smoothed out well. Low odor and cured properly after about a week. Adhesion seems strong and I expect it to last.

Trouble-free waterproof sealing for wet zones
Worked well around sinks and tubs — easy to apply, adheres firmly, and the white finish looks clean. Its waterproof, shrink- and crack-resistant formula makes it suitable for wet areas.

SemoTech 5/5
Dependable, long-lasting bathroom sealant
This caulk is my go-to for tub and sink repairs. It applies smoothly with a steady bead, stays flexible after curing, and keeps water out. No cracking or shrinkage after hot showers. Mildew resistance held up—no discoloration in the humid guest bath. White finish blends in with grout. Minor gripe: the nozzle could be narrower for tight spots.

GORILLA clear silicone comparison note
Heads up: GORILLA clear silicone is extremely durable and very waterproof, close to two-part epoxy in toughness. Use acetone to remove it from skin — it’s hard to wash off. It isn’t right for every caulking or bonding job.

Functional caulk with long shelf life
It’s just caulk — straightforward. The expiration date was more than a year out.
