How do you seal a fiberglass shower seam with a large gap?

Question

My shower has a huge seam (3/4" wide, 1" deep) between the side panel and the bottom shower pan that I need to seal. What is the best way to seal it?

Answer 1

silicone caulk, but you will have to do it in stages.  If you fill it all in at once, it won't dry properly.  Fill in some, let it dry and repeat until it's filled in.  I had large gaps in my kitchen between my stone backsplash and my less than straight walls and it took about a week to get it all filled in correctly.

Be careful that you start with it completely dry and that each "layer" is completely dry before starting the next.
