PVC cement

Unread postAuthor: YEAHADD16 » Mon Aug 24, 2009 10:24 am

This has happened to me two too many times,

I buy cement, use it, then i store it in a decent temperature place (55-60 degrees F give or take) an then after about 3-4 weeks later, it turns to a semi solid glob, unusable. I make sure it tighten the cap as well.

Is there anyway to prevent this from happening that i am forgetting, and/or is there a way to fix it if it happens again

You have to tighten the cap with pliers or else you just won't get a good seal. I had this happen to me once and learned from my mistake. Most importantly don't use gelled glue as it creates a lot of bubbles when applying it the PVC. This may weaken the pipe considerably. I'm Not aware of any safe way to revive the glue. I have heard of people using primer/cleaner to thin the cement but I don't recommend doing so. Good luck.

Most likely problem is that you aren't closing the cap as tightly as you think you are. The acetone, THF, and MEK solvents will evaporate pretty quick if there is any air leakage around the cap. If you get a blob of glue on the neck of the can that blob will make it hard to get the can to actually seal when it is closed. (I suspect manufacturers purposely make the cans hard to reseal so you'll have to buy glue more often. :roll: )

Wipe off the threads and top of the can, and inside threads and gasket of the lid, before closing the can back up.

If you are using small cans of glue (and cleaner/primer) you can fit both into a large zip-lock bag. If the bag is closed tightly that'll keep the glue from drying out even if the can lid isn't perfectly sealed.

This isnt related to the toopic but I've always wondered whats the difference over the green pvc glue labeled heavy duty cement and the traditional black pvc cement by black I'm talking about the color on the can. From what Ive noticed the green type is much more , gooey , it flows less easily, it has more vesocsity, ive heard that the more viscosity the longer it takes for the glue to dry/harden, in the other side the black one is a little smoother and less "thick"... so is does the green one provide anymore "strength" or "seal" :?:

if ur an aussie green glue is usually for pressure rated pipe and fittings

blue glue is for non pressure rated applications

if the glue is semi gluggy try putting some primer in there and mixing it around

"Heavy Duty" cements contain more PVC resin and less solvent. They are designed for large diameter pipe and fittings, where the cement must have better gap filling properties. Regular PVC cement is ideal for common spudgun pipe sizes.

ummmm .yes they may contain more resin and less solvent,but no there not used for larger diameter pipe,if ur using a fitting that is that lose,its probly not approvend.
the whole point of pvc cement is to weld/melt the inner/outter layer of plastic and fuse the two toghether,if there was such a gap no cementing would take place.

It happened to me one time but it was because i had left without the cap on for like 4 days. Its kinda like nap$@m when bu@#t. Edited for flammable reasons. Use Oatey brand cement for best results.

You don't seem to understand the design of PVC fittings. All fittings are tapered for an interference fit at the bottom, yes. However, larger diameter fittings have a larger gap near the top, and a more viscous cement is required to fill in said gap. Heavy Duty cements are designed for larger diameter fittings.

Also, please learn how to spell.

Its amazing how much people don't use spellcheck isn't it? More on the pvc cement i've never seen green pvc cement. Maybe its because I don't use at all.
