Hello all,

I wanted to build a 3d styrofoam background for my aquarium. Examples can be seen here

But you know, singapore being singapore (I wish we can have a home depot here lol), ready mix cement for the consumer use is hard to find. I wanted to use screed though, but i am not sure if it is an okay replacement?

These are the ones I'm looking at
