Pool light Conduit Putty

[red-beard]

I replaced one of my lights over the weekend (see other thread on why only one light).

In the niche, as we fished the cables through the conduit, it looks like my builder "sealed" the conduit with a putty. Seemed like a sticky clay. I expect it is to prevent water from going in and out of the conduit. But it was not a true sealant (like silicone caulk) but again more like a sticky clay. The stuff has been in there for 13 years.

Any idea what this stuff is? On another site, it was suggested to seal the conduit with underwater epoxy. One end of my pool also had clear silicone.

Thoughts? suggestions?

From The Many Uses of Pool Putty for Pool Repairs | InTheSwim Pool Blog

Pool Light Leaks: The conduit, or pipe that connects from the pool light niche and the light junction box can become cracked from movement or freezing, and can become a source of leaks in an inground pool. Many pool guys will use pool putty to make a conical seal around the light cord – at the point where it enters the conduit. Again, this is a convenient method, used when one doesn’t have a Light Cord Stopper handy, or would prefer not to rip up the concrete deck to replace the broken conduit (uggh). Leave the pool light undisturbed for 24 hours before reinstalling the light into the niche, to allow the putty to set up. Using pool putty on a leaking pool light is preferable to using silicone, which can be difficult to remove when replacing the pool light.

If I use epoxy, I don't think I'll ever be able to replace the pool light, if it is needed.

I think a pool epoxy putty like this is removable unlike the hard epoxy you are thinking of...

I ordered 2 of the stoppers and will put some caulk on them. I expect that was the "goop" I found. Maybe it dissolved.
