I have a small 1-inch long, half-inch wide white plastic 'tab' that fell
off which holds a cover down.
It's all under water (a few thousand gallons would have to be removed to
expose it to air).
It's plastic on plastic.
Any suggestions for a good glue that works underwater?
Is there such a thing?
What type of plastic? If it is styrene, there are many good solvent based
adhesives that could work. It it is any type of polyethylene material, there
is no adhesive that will work.
There are thousands of potential blends of plastic. Need more info.
What did they tell you at the pool store?
(It was years ago, details now forgotten, but when I showed
the pool store expert various parts disassembled from a
filter, he told me two items were broken, i.e. ought to
comprise a single unit: and recommended an appropriate
adhesive: which worked.)
epoxy works underwater.
but getting a clean surface to bond to might be a problem.
gotta rough it up,too.maybe dril some holes for extra bonding surface.
Can you unscrew or remove the broken part and glue it above water?

Well, the 'cannister' is a good foot below the base of the skimmer so I'd
be pumping out thousands of gallons of water (maybe even a foot and a

Yes, I could pump the water out (disabling the pool until I put 'back'
thousands of gallons); but I was hoping for an underwater glue.
My pool store would send you home with a stick of 2 part epoxy paste,
made for the purpose. It is also what the appliance repair store
sells. The trick is getting it to bond. You really need to work it in
to both surfaces well to expel the water. I fixed a skimmer once and
it did work. Be sure you wipe the parts down well to get any surface
oil scum off before you start. Scuffing it up with some 150 grit wet
dry paper can help too. You usually just get one shot at this so
preparation is everything.
I had never heard of http://www.thistothat.com before so thanks for the
Unfortunately, they don't have anything whatsoever on their site that
says it will work under water.
Their glue calculator, for example, to glue "plastic" to "plastic",
simply comes up with:
"If you are gluing PVC plumbing pipes, we recommend: PVC Adhesive
If you are gluing something else and your joint needs to be flexible use:
Otherwise, use: LePage's 5 Minute Epoxy or LePage's Regular Minute Epoxy"
devcon has a 2 part putty epoxy. available at home depot. i use it to attach
corals to rocks in my salt water tanks. it cures underwater just fine, but
it has to have some sort of mechanical lock, so you have to rough up the 2
That 'might' work.
It says 'waterproof' but nowhere does it mention that it can cure under
