How many times should the primer be applied to the fitting socket of a PVC solvent cement joint?

Apply a second application of primer to the fitting socket. Do not allow primer to run down the inside of the fitting or pipe. 12. With the proper size and type of applicator, while surfaces are still wet, immediately apply the appropriate Weld-On® cement.

Does PVC cement work without primer?

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.

How long should PVC cement set before turning on water?

After joining the pipes you must hold them together for 30 seconds until the plastic hardens or they can slip apart. It takes another 15 minutes for the joint to harden to a point at which it can withstand water pressure and two hours to fully cure.

What is the difference between PVC glue and PVC cement?

Q: What is the difference between PVC solvent cement and PVC glue? The solids contained in the solvent cement will then fill the gap between the pipe and fitting. Glue such as PVC glue, on the other hand, is only a bonding cement and will not work with an interference fit.

What is the difference between blue and clear PVC cement?

Medium Clear PVC Cement: Fast drying and suitable for potable water, pressure pipe, conduit and DWV applications. Hot Medium Blue Lava PVC Cement: Extremely fast setting and the preferred formula for emergency, repair and cut-in work for potable water, sewer and DWV applications.

How long does it take oatey PVC cement to dry?

Allow 15 minutes for good handling strength and 2 hours cure time at temperatures above 60 degrees Fahrenheit before pressure testing up to 180 psi. Longer cure times may be required at temperatures below 60 degrees Fahrenheit or with pipe above 3 inches. DO NOT TEST WITH AIR.
