GE II Silicone vs. Thinset for outdoor application
My next project is going to be an outdoor shower, done with stained glass on Wedi. I've seen advice here that GE II is a great clear adhesive. My question is, do I need it? Since I'm gluing to Wedi, which is, of course, opaque, does it matter if I use a clear adhesive? The glass tessarae will not all be opaque, unless there's a reason they should. I planned on doing as much as I could with glass I already own, rather than going out to buy more. So some will be opaque, some not.
My plan has been to create the piece on mesh and then adhere it to the wedi with thinset later. If I decide to use GEII instead, would the best option be to glue directly to the Wedi?
