Plumber's putty does not have a specific drying time because it does not actually need to dry to create a seal. It remains soft and pliable after application, allowing you to use the fixture immediately or after a short wait—usually about 10 minutes in colder conditions—to ensure a watertight seal. Unlike silicone caulk, which requires hours to cure, plumber's putty creates an effective seal as soon as it's installed and squeezed into place. Over time, it will eventually harden but that process can take years and is not necessary for the seal to function. Also, plumber's putty is reusable and can be wiped away easily if there is excess during installation.
Key Points on Plumber's Putty Drying Time
- No actual drying time is needed for use.
- Use the fixture immediately or wait about 10 minutes in cold/humid conditions.
- Remains soft and pliable for a long time.
- Creates a watertight seal by being pressed and squeezed into place.
- Eventually hardens over many years but not required for sealing.
- Excess putty can be wiped away easily after installation.
This makes plumber's putty very convenient for plumbing projects such as installing faucets, drains, and strainers where an immediate seal is desired.
