Hello, I built my oun background to inside my tank for my Red-Eye Treefrog. I carved it out of floral foam and used grout to make it hard. Yea that was a lot of fun... After the grout was cured for 48 hours I spray painted it and now I need to seal it so that it would be safe for my treefogs. The background is going inside the terrarium due to the fact I have mad potters that are in it. Does anyone have any suggestions for sealing it other that using clear calking or Aqurium Selant? Thank You.
