Primer

PVC and CPVC primer is an important step in creating a strong and lasting joint. Many building codes require use of primer wherever you are using PVC or CPVC solvent cement. The primer, as the name implies, gets the pipe and fitting material ready to be joined together. It is applied right before cement to clean and soften the material so it can create an optimum weld. Most primers are suitable for both PVC and CPVC materials. They usually come in either a clear or purple color. Purple primers are commonly used where local code requires proof of primer application on joints.

To really be effective, a primer needs to be wet while the cement is applied. That means you should prepare your pipe ahead of time and work quickly once the primer is applied. PVC and CPVC primer and cement are unique in that they chemically soften the rigid pipe material so it can bond together. Primers are useful for removing grime and getting the PVC or CPVC ready for joining.

PVC/CPVC primers are usually a fairly viscous liquid and should be applied using a brush. Our primers include in-cap brushes that make application easy. Big jobs may require additional or larger brushes. Many plumbers and contractors choose to use purple primer beyond where the pipe and fittings will meet. This leaves a visual they can point to if code requires validation of primer use on all joints.
