Usually PVC jobs require about half the amount of primer as they do cement. In short, primer is your friend. It may not be completely necessary on all jobs, but we recommend you take all the precautions available to ensure your joints are leak-free and as strong as possible.
What happens if I don’t use primer on PVC?
PVC primer maximizes the strength and longevity of the joint connection. A joint will still weld together without the primer, but the connection will not be as strong as the primer allows the cement itself to penetrate deeper into the material.
Does PVC conduit need primer?
PVC Conduit Doesn’t Need Primer
Some PVC pipes require primer, but you don’t need to use primer when gluing conduit and fittings. Home centers usually sell the appropriate glue/cement near the the PVC conduit and fittings. Measure as carefully as you can so you can avoid dry-fitting your connections.
Does PVC need to be primed before painting?
Does PVC trim require a primer? A primer is only needed if you want the paint manufacturer’s warranty. Excellent adhesion can be achieved by properly cleaning the board before applying a topcoat of paint to PVC trim.
Do I need primer for CPVC?
Primer is needed to prepare the bonding area for the addition of cement and subsequent assembly. Use a proper applicator, such as a dauber, swab or paintbrush, approximately half the size of the pipe diameter.
How do you seal PVC conduit?

- STEP 5: Apply spray paint.
- STEP 6: Apply second coat.
- STEP 7: Let dry for 24 hours.
Can PVC be connected to CPVC?
There is no special “CPVC to PVC glue,” so chemically joining CPVC and PVC requires solvent cement and primer that are strong enough to fully bond CPVC pipe. To connect PVC to a CPVC fitting (or vice versa) follow these steps: Brush CPVC primer on the outside of the pipe and inside of the fitting about 2 inches deep.
What happens if I use PVC glue on CPVC?
When working with CPVC piping, use multipurpose PVC/CPVC glue or a CPVC glue; glue made specifically for PVC will not hold properly on CPVC and could lead to leaks or breakage. CPVC pipes can withstand hot water temperatures up to 180 degrees F. Cut the CPVC pipe to size with a fine tooth saw.
How do I fix a leaky CPVC joint?
Each joint should be clean and dry, use a hair dryer if needed. Coat the whole of the pipe surface with PVC cement, then coat the inside of the joint with a thin layer of cement. Quickly push the joint onto the pipe and give it a quarter turn. Leave it for 5 minutes before touching it again.

How long should PVC glue dry before turning on water?
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.
Does ABS pipe need primer?
Primer: Primer is used to clean and soften the surface of the plastic to ensure a good solvent weld. It’s used with both PVC and CPVC, but is not required with ABS.
Why do you need PVC primer?
The purpose of primer is to begin the chemical reaction that softens PVC and to provide an even prepped surface for the solvent cement. As you may know, PVC joints are not glued together exactly, but fused through a chemical change. The softer the outer layer of your PVC, the better it will cement in your joint.
Does conduit need to be sealed?
In the 2014 NEC, conduits or raceways through which moisture may contact live parts must be sealed or plugged at either or both ends.Condensation and moisture from an underground raceway can just as easily enter an enclosure whether conductors are installed in the raceway or not.
