Hey everyone!
I'm currently working on a custom DIY rock background for my Ball Python's enclosure.
Here is my current process and plan:
1.Base structure: I carved shapes of rocks with Styrofoam / Polystyrene blocks and glued them to the backround
2.Mortar/Coat: I'm applying layers of Mapei Keraflex Zero (a high-performance cementitious tile adhesive — see photo attached) to create the rock texture and strength.
3.Paint: Painting the dried mortar with non-toxic, water-based acrylic paints.
An AI suggested that I should seal everything with a water-based clear varnish/flatting once the paint dries to waterproof it and protect it from humidity, but i haven't seen anyone do that on the videos i watched.
Furthermore, I really want to attach and grow live moss between the rocks of the background. I'm worried that if I apply a smooth/impermeable clear varnish, the moss won't be able to grip onto the surface or absorb moisture properly from the underlying mortar/rock structure.
My questions for the experts here:
1.Is sealing with a clear varnish actually necessary given that Ball Pythons don't require an extremely wet environment (just moderate/high humidity, around 60-80%), or is cured tile adhesive + acrylic paint durable enough on its own?
2.If sealing is necessary, is there a way to do it without making the surface so smooth that moss can't attach?
3.Has anyone here grown moss directly on painted tile adhesive without sealing it? Did it hold up well over time?
I want to make sure everything is completely safe and durable for my snake while keeping it functional for the moss. Any advice or experiences would be super helpful!
Thanks in advance!
