My great stuff background is coming off on the sides! I can't fix it. I'm really worried it will fall off and kill my frogs and plants! It came off the right side very fast and soon following it's now coming off the left! It hasn't reached the very back wall yet, but it might be next. Here's pictures to show you what I mean. Will it fall off? Thanks! I'm just really worried that if it gets to the back i'll have to restart. I didn't put silicone on before I put the GS on. I put the GS on in 2 layers, letting it dry for an hour between spraying.
