So I can't stand plain vivs so I wanted something with a decent look to it.
Built a basic 3x2h viv and fitted a nice large vent. Then blasted a load of expanding foam inside it.
Spread that around using spatula (stops it expanding too much and looks more rocky when cured) and on top of that pasted a thick layer of cement over the top.
2nd layer of cement also mixed in some brown acrylic paint to give it some life.
Few more sealing layers and will be done
Updates to follow.
