One day my wife was showering and some water starting coming out of a light fixture underneath the shower. I opened it up and didn't see any leaking pipes, and determined it was around the gasket interface in the actual drain itself.
To address this, I have been using a layer of clear waterproof silicone on top of the black gasket part, and it has helped but after time the silicone degrades and comes off. Can I instead apply one or two coats of RedGard waterproof membrane on the gasket and surrounding areas? Does anyone see an issue with this? Or another recommendation?
