With kind advices from this forum, I replaced my shower drain stall and pipe. Finally, I applied silicon caulking bottom of Oatey stall and the boundary of it and my shower floor. I believe my floor is fiberglass (it's not tile). After two days, I did leak test and fount leaking from between the floor and the stall. I checked the silicon that I applied. I could rip it off. It was cured but did not adhere on the floor. I cleaned the surface before I applied. Even I tested on other spot to check if it stick on it. But it does not stick on it even it is cured. Did I misunderstood on using the silicon on this project?
Thanks for your help.
