My Experience with GE Silicone 1 and GE Silicone 2: A Hands-On Test

Last year, I remodeled my bathroom, dealing with leaky shower tiles and drafty windows.

I grabbed GE Silicone 1 and GE Silicone 2 to see which performed better.

Both come in 10 oz tubes, easy to load into my caulk gun.

Silicone 1, with its acid-cure formula, had a strong vinegar smell that filled the room, but it adhered quickly to my glass shower door.

I smoothed it with a wet finger, and it sealed the edges without dripping.

After 24 hours, it was waterproof, and my shower stayed leak-free through daily use.

My wife liked how it held on ceramic tiles, but the smell lingered for days.

Silicone 2 was a different story—low odor, almost neutral, making indoor work pleasant.

I used it on the bathtub surround, and its neutral-cure formula bonded to the porous grout lines perfectly.

It was water-ready in 30 minutes, so I tested the shower soon after, no leaks.

My friend borrowed Silicone 2 for his kitchen sink, praising its mold resistance in humid spots.

At $5 for Silicone 1 and $7 for Silicone 2, the extra cost for Silicone 2 felt worth it for baths.

I tracked durability: Silicone 1 yellowed slightly on my exterior window trim after summer sun, while Silicone 2 stayed clear on indoor fixtures.

You’ll notice Silicone 1’s faster initial tack but slower full cure.

Both are 100% silicone, waterproof, but Silicone 2’s flexibility handled my expanding wood frames better.

My bathroom seals have held up for a year—no mold or cracking.

You should test small areas first to see adhesion.

I pushed them in various projects.

Silicone 1 sealed my metal garage door frame, sticking well to aluminum, but the vinegar fumes made me open windows.

Silicone 2 went on my porch railing, and its Class 35 flexibility prevented cracks from temperature swings.

My neighbor used Silicone 1 for his vinyl siding, happy with the price, but he complained about the cure time in rainy weather.

I analyzed adhesion on wood, glass, and tile—Silicone 2 won on porous surfaces like concrete, where Silicone 1’s acid etched slightly.

You’ll find Silicone 1 suits quick, non-porous jobs, while Silicone 2 excels in wet areas.

The cleanup was easy for both—mineral spirits wiped away excess.

My total spend was $12 for two tubes, covering 50 linear feet.

You can tackle home repairs confidently with these.
