3D Background Question

[Gebus]

As the title says I'm doing a 3D Background for my 90Gallon. I'm using Polystyrene/styrofoam as the base for it.

I know all the steps, and how some people use Quikrete and some use DryLok. I'm here about a different product that gives the same look and texture. I have built two backgrounds for reptiles using Polyfila Tile Grout, I'm wondering if I am able to use the same stuff for this? It's fairly easy to spread and I'm familiar with it.

Any suggestions as to what to use and how to go about doing this to get a nice dark black effect and sealing it without causing any problems in the long run will be greatly appreciated.

Thanks for your time, Ben

I have seen tile grout used as a background cement on a YouTube video, but never made a background myself so wouldn't like to comment.

Good luck though and please post a pic.
