I was doing some caulking work on the bathtub edge. I did it the same way I used to. This time round, something funny happened. Parts of it started coming off during a shower. It was a bit sticky and feels like it was melting. The stuff hardens after it dried up.
I had it left there for over 40 hours before I took the shower. The water may be hotter than usual but that is the same water temperature I have used in the past. Does anyone know why?
