What is the difference between PVC glue and PVC cement?
'PVC glue' is also referred to as PVC cement or solvent cement, the official term for the product. There are solvent cements for a wide range of pipe materials, including CPVC, but the substance will only create an effective bond when used on the matching material type.
Should you sand PVC before gluing?
In know that PVC should be chamfered and even lightly sanded before gluing for better insertion on the fitting (and probably some other reason).
Can you use too much PVC cement?
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.

Do you need primer with CPVC glue?
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. Apply the primer to the inside of the fitting socket and to the outiside of the pipe end.
Why do you need primer on PVC?
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. This is how primer helps your joint strength.
What color is a plumbing primer?

Why are primed joints weaker than unprimed joints?
The final reason why the primed joints could be weaker than the unprimed joints could be that because the cement contains most of the same ingredients as the primer does , the primer may not have added any real benefit to the joint strength. The primer may have actually made the joint weaker.
What is the second step of solvent welding?
The second step of the solvent welding process requires the use of a cement, which is composed partly of PVC (Oatey, 2012). This helps the two pieces of material in that it provides a surface on which the two materials can fuse. It also contains acetone, which softens the materials to ensure maximum joint strength.
What is PVC made of?
PVC, or polyvinyl chloride, is made up of mostly chlorine and carbon (Johnson, n.d.). CPVC, or chlorinated polyvinyl chloride, is similar to PVC material, but contains a higher amount of chlorine, allowing it to withstand a wider temperature range ("What's the difference between PVC and CPVC pipe", 2012).
What is the first step in welding?
The first step is pressing, and it is required to ensure contact between the two pieces being welded, maintain proper orientation of the pieces and to force intermolecular diffusion between the two pieces. The second step is getting the temperature of the material over its Tg by use of a cement.
Is PVC a crystalline material?
Both PVC and CPVC plastics are amorphous in composition. This means that they do not have a crystalline structure when they are in a solid state ("PVC's Physical Properties", n.d.).
