    I'm in the midst of a new build (36 × 18 × 18) and I tried using a wood glue for my substrate on the backgound after applying the spray foam. The wood glue (and me) didn't do such a great job, and I have small white gaps all over the background.
    I have tried using brown silicone to fill these gaps but it will take hours. Has anyone every spray foamed over and reapplied the background or do you either wait til plants grow (to hide the mistakes) or cut out the previous foam amd restart?
    Thanks for your feedback!

    I have not, but I have used glue in a mix for covering foam. I used a mix of coconut fiber, sphagnum, tree fern leftovers, Titebond III, and water. It tended to hold well and was easy to adhere. The only thing is you are left with a very hard background that will not really absorb water.
