When you slide the joint together, the two surfaces blend together. The process is properly called "solvent welding". Partial set time rating: Fast - approximately 45 seconds. Complete cure time is 24 hours. The glue itself is not very strong. But, it's not the glue that really holds the pipe joints. The " glue " is really a solvent for the plastic pipe. It chemically "melts" the plastic and the plastic hardens back again.
What to expect: unopened, a can of ABS cement could expect a shelf life of at least a year, if not exposed to extreme high temps. Once opened, 3 months is probably going to be it. If you're plumbing in a new drain or vent and have to join two different kinds of plastic pipe , black ABS and white PVC , don't assume that you can simply glue them together.
Check with your local plumbing inspector. Ideal for conditions where moisture is present. Can cure underwater. This well help to soften the PVC glue. Saturate a cotton ball with acetone nail polish remover. Rub the cotton ball on the glue on your hands. Rinse your hands well under warm water. It may be used outdoors if the pipe contains pigments to shield against ultraviolet radiation, or jurisdictions may require the pipe to be painted with water-based latex paint for outdoor use.
It is the viscosity of the glue that pushs them apart, which is why the instructions tell you to push it in and hold it for a few seconds until the adhesion takes place. I have no problem reusing any fitting, just put primer and glue on them and slide the pipe in.
The fitting can be re-used if cleaned properly. What is the shelf life of the cement and primers? If you apply the PVC cement to the PVC pipe, it softens the plastic, and when you press together the two pieces, they fuse into a single piece. The plastic hardens when the solvent evaporates. If you are joining PVC pipes, you must apply PVC primer to the surfaces of the areas that you will be joining of the pipe and fitting, if the cement you are using requires it.
Many if not most manufacturers recommend primer before glueing, but there are all in one product that eliminates that need. Apply a large amount of cement to both parts and quickly join the pipes before the solvent evaporates. You will only have about a 15 to second window to create this bond , perhaps a little longer in a cooler environment.
After you joining the pipes you need to hold them together for at least 30 seconds so the cement can harden. It will take another 15 minutes for the joint to set to the point that it can withstand water pressure and another two hours to cure fully.
Rain or Shine is a medium bodied blue cement for use on PVC pipe. It is rated for very fast setting, and it is a hot cement formulated for wet conditions and quick and rapid pressurization. This cement is best recommended for pools, irrigation, and pressure pipes. No primer is needed. It should be stirred and used as is. It should not be thinned and should be discarded if found to be stringy.
Use within three years of the date stamped on the can. It sets very fast and can be used without primer. After that, you will immediately insert the pipe into the fitting.
Twist the pipe a quarter of the way around as you push it into the fitting. This will allow the glue to spread, offering a tighter fit. Hold the pipe and fitting together firmly for at least 30 seconds; any less and the pipe could pop back out. 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.
