I went to use my PVC glue last night and when I opened it, the glue instead had
the consistency of jelly.
The can specifically says, "Do not use if jelly like." Does that really mean
this can of glue is trash? It's mostly full too! I only bought it like 4 months
ago. What causes this? A loose lid?
Anyway, if anyone can give me some tips on how to avoid this problem in the
future, I'd appreciate it... (or even better, how to salvage my mostly full can
Yep, it's gone...unless you happen to have a little tetrahydrofuran
and/or methylethyl ketone laying around to replenish the solvent and
"juice" it back up. Next time, cap it up tight, turn the container
up-side down for a few seconds, then turn it back upright and store on
the shelf. The upside-down treatment puts some of the glue directly
at the top of the cap, which will seal the minor air leaks through the
threads. The stuff will eventually go bad anyway, but this will give
you the maximum life.
PS - this also works to seal paint cans!
Sounds like a cool trick, but will that make it doubly hard to open the can?
Last time I tightened the can super tight, I needed channel locks to get it open.
I'm pretty sure the reason this went south so quickly was that I didn't tighten
Thanks for the advice,
I have never known this trick to make it terribly hard to get the can
open. I usually just grab it with a pair of channel locks anyway.
Because you are tipping the can after it's already sealed (and only
for a couple of seconds) you aren't really coating all the threads,
just forming a little seal at the very top. From the way it sounds,
you could back off a little on the initial tightening and let the
"trick" do the work. At a certain point, overtightening the can lid
just makes things worse...they aren't like pipe threads or anything
with a tight tollerance...just bits of stamped steel. Go too tight
and they just deform and let in even more air (or more precisely, let
your solvent out!)
All plastic pipe cement cans have a seal in the lid. In 15 years of
sometimes daily use, I've only had a problem of 'jelly' glue (once or
twice) when I didn't tighten the lid properly. When I do it properly, I
always have to use channel lock pliers to open the can. Same for the
cleaner. I never use them to tighten lids, just my hands. And I don't
mess up the inside and cap of the can, or the can threads, by tipping
the can upside down. Damn I hate a messy glue can! But I always set the
lid back on the can between dauber entries and actually tighten it if
I'm not going to use it again for a few minutes. That keeps my various
cans good for many months. When I buy a new can, I tighten the lid by
hand and some sit for a year or more before I use them, and I only do

Typical Home Moaners post. Thirteen year old thread. Would it work
as a solvent? Sure, I'd use it to get PVC cement off my tools or maybe my
fingers. Would I use it to thin out old jelly like cement and use it

Toss it, it's trash.
You can not keep that stuff very long, no matter how tight you make
the cap. Who knows how long it sat in the store too.....
I never buy more than I need. I too, learned the hard way.
Note: In a pinch, I did use jellied glue once and it worked. Depends
on how stiff it is..... I do not recommend this, but in my case I had
no choice, it was 2am and a weekend, and nowhere to buy more glue. It
was drainage too, so no pressure. It's still attached !!!!
That was my exact situation... I'm doing drainage... so for kicks I tried using
it on one fitting until I could get out to HD the next day, when I got home, I
tried my best to rip off the fitting and no go,.. so I probaby could've saved
money on a new can since I only had one more attachment to do, but oh well...
