FAQ: How long should you wait after gluing PVC?

DO allow enough cure time. After holding the pipe in place for 30 seconds, give it at least 20 minutes before handling it further so the cement can set properly. Refer to the product’s instructions for how long the glue needs to cure before you can use it for your project, usually within 24 hours.

How long should PVC glue dry before turning on water?

Do you let PVC primer dry before cement?

2 Answers. No – PVC Primer does not need to ‘dry’ before use – in fact, it needs to be wet to do it’s job and not impede the cement – remember, plumbers in a hurry use this daily and aren’t sitting around waiting for the primer to dry before grabbing the cement.

Can you use too much glue on PVC?

Using too much solvent cement can cause the PVC to dissolve to the point of weakening the joint, lessening the integrity of its waterproof capabilities. However, if you use too little solvent cement, the pieces may not be fully welded together, which may lead to leaks or other problems down the road.
