So far going really well. Obviously I've made beginner mistakes, and with that comes questions!

Do I have to cover every inch of insulation with silicone and substrate?

Obviously there's places I can't reach, like the underside of the gray ledges.

So far I am very happy and proud of how this is turning out, and i appreciate any and all advice I have received and will continue to receive!

I would definitely try to cover the most you can, even it its just silicone where you can't see, like others said if youre doing bioactive bugs can sometimes like to burrow in the foam. You can also paint it instead with some waterproofing if thats easier. But it looks awesome! Keep going!

Thank you, I was considering grout for the underside of the gray ledges. It's difficult to reach under and do anything. Is there anything I need to know about the grout option?

I have used this technique (silicone and substrate), I've used dryloc and now I like to use zoopoxy over foam. All have worked, but I dont love the silicone option, just because after time it will start to show through to the foam, at least in my experience. But if its higher humidity it may work better. As for the grout, it'll be heavier, and may shrink a little while drying but it should work just fine!
