Looking to take on a PVC/CPVC project? PVC “glue” isn’t really glue at all, but solvent cement. The cement creates a chemical reaction that actually softens the rigid PVC material and allows it to fuse to another piece of softened PVC. Before purchasing your cement, do a little research. You need a product that is specially formulated for PVC. Don’t try to use that old epoxy you have in the garage. A few well-known cement companies are IPS (WELD-ON) and Oatey.
Generally speaking, a little PVC solvent cement goes a long way. If you are simply replacing the sink trap in your bathroom for instance, one quart of cement will be way more than enough. If your project is a little bigger though, you may be wondering how much cement you will need to complete the job. We’ve created a chart to help you calculate the approximate amount you should budget for.
Before you begin, you’ll need to know the size pipe you are using and about how many joints you plan on creating. Use the chart below to find your pipe size – then look over to see how many joints can be cemented using one quart. Keep in mind these numbers are approximate, and should only be used as a rough estimate.
Average Number of Joints per Quart of PVC/CPVC Solvent Cement
|Pipe Diameter||½”||¾”||1”||1 ½”||2”||3”||4”||6”||8”||10”||12”||15”|
|# of Joints||300||200||125||90||60||40||30||10||5||2-3||1-2||3/4|
*One joint means one socket. Chart is a general reference only. All numbers are approximate and will vary based on conditions.
Will your job require large diameter pipe? If so, you’ll probably want to look into bulk ordering your cement. Cement suppliers offer quart sized containers for small to medium sized jobs, but they often have gallon sizes available and will give you a price break for ordering in bulk.
Wondering how much primer you will need? Typically a job will require about half as much primer as it does cement. If your job takes 4 quarts of cement, for instance, you will need about 2 quarts of primer. Be sure you check the use date on your products before beginning a job. Typical shelf life is about 2-3 years for most PVC cements. If your old can of cement has been sitting in the garage for longer than that – throw it out! No sense in compromising a job over a quart of cement.
