PVC glue (also known as PVC cement) typically takes about 15 to 30 minutes to set enough for handling, and around 2 hours to reach sufficient strength for standard water pressure use. However, for full curing and maximum bond strength, especially under higher pressure or industrial conditions, it is recommended to allow up to 24 hours before subjecting the joint to stress or pressure
Factors Affecting Drying Time
- Temperature: Warmer temperatures speed up drying; ideal application temperature is between 40°F and 110°F. Cooler temperatures slow the process
- Humidity: High humidity slows drying by retaining moisture; low humidity promotes faster drying
- Pipe Size and Pressure: Larger pipes and higher operating pressures require longer setting times. For example, a 2" pipe at 2 bar pressure needs about 2 hours setting time
- Type of PVC Cement: Some fast-setting products can dry in under 30 minutes, while regular types take longer
Practical Guidelines
- Wait at least 15-30 minutes before handling the joint lightly.
- For normal residential plumbing, 2 hours is usually sufficient before turning on water.
- For high-pressure or heavy-duty applications, wait 24 hours for full cure.
- Avoid applying pressure or stress on the joint during the curing period to prevent leaks or joint failure
In summary, while you can handle the glued joint within half an hour, allowing 2 hours before use is standard, and 24 hours is best for full strength and durability.
