A 100% silicone kitchen-and-bath sealant that is permanently flexible and fully waterproof, with strong mold resistance for showers, tubs, and sinks. It is water-ready in about 30 minutes. Trade-offs: it cannot be painted, gives off a strong vinegar-like odor while curing, and tools less easily than latex caulk, cleaning up only with solvent.
Pros
- 100% waterproof and permanently flexible, making it ideal for showers, tubs, and sinks
- Strong mold and mildew resistance for a long service life in wet areas
- Ready for water exposure in about 30 minutes, so a shower can be used the same day
Cons
- Cannot be painted, so the caulk color you choose is the color you keep
- Strong vinegar-like acetoxy odor while curing that needs good ventilation
- Harder to tool and smooth than latex caulk, and mistakes clean up only with solvent

Frequently Asked Questions
- Can GE Advanced Silicone 2 be painted?
- No. It is 100% silicone and paint will not adhere to it, so the colour you buy is the colour you keep. Match the caulk to the tile, tub or trim before applying. If the joint has to be painted, use a paintable latex or siliconized-acrylic caulk instead.
- How soon can the shower be used after caulking?
- It is water-ready in about 30 minutes and reaches full cure in roughly 24 hours, so a shower recaulked in the morning can normally be used the same day. Wait for full cure before heavy scrubbing.
- How do I clean up silicone caulk?
- With mineral spirits, not water. That is the main handling difference from latex caulk: it is harder to tool smooth and mistakes will not wipe away with a damp finger or rag, so mask the joint if you are not confident.
- Silicone or latex caulk for a bathroom?
- Silicone wins on waterproofing, flexibility and mould resistance, which is why it belongs in showers, tubs and sinks. Latex wins on being paintable and much easier to tool. For a wet joint that stays its own colour choose silicone; for a joint you plan to paint choose latex.
