Thanks for your reply don, i did want to clarify a few things though. I let the great stuff sit in my garage for 6 days before adding silicone and let the silicone sit for 3 days(opened the garage a bit) I did use a small amout of acrylic paint to touch up some spots that i missed and i have a feeling that is where the smell came from. I thougt the brand was VOC free but i will double check the can. I will most likely get some more silicone and silicone over the places i used the paint.
As for the bricks i need something for them to adhere to one another and then attach the bricks to the glass with silicone.
I do not want to trash my first background because i spent a lot of time on it. Its possible that i can still use it in my bearded dragon cage. Is there a safe brown colored silicone i can use?
Thanks for your help
