Most sealants should stay dry for ít nhất 24 giờ after application. For areas with heavy water exposure, waiting 48 giờ an toàn hơn.
Đối với keo silicone, a common rule is:
| Situation | Recommended wait time |
|---|---|
| Light moisture or humidity | Usually okay after skin forms, about 30 minutes–2 hours |
| Rain exposure | At least 4–24 hours, depending on the product |
| Shower, sink, or constant water contact | 24–48 hours |
| Full cure | 24–72 giờ |
The safest answer is: wait until the sealant has fully cured before letting it get wet. Even if the surface feels dry, the inside of the bead may still be curing.
Sealant can get wet sooner only if the product is labeled rain-ready, wet-surface compatible, hoặc fast-curing. Always check the manufacturer’s label, because curing time varies by sealant type, bead thickness, temperature, humidity, and ventilation.
