What it the best epoxy to fill the pool light conduit? I will be removing my light and I want to permanently seal the conduit. I plan on putting and expandable rubber plug in it first to use it as a backing and then seal it with an epoxy.
The water level is right in the middle of the conduit right now, so I have a choice to let it drop below and do the work dry or wet.
It seems that I could use pool epoxy (putty like resin and hardener) and marine epoxy (gel in 2 syringes) . Even though both can be applied underwater, I imagine the first would be easier.
Also, does anyone know what the typical inside diameter of the pool light conduit is?
