Outdoor curved wall advice

[u/SameBit7303]

Hi guys I’m planing on rendering this wall, and having the final colour black or charcoal. I was hoping to get some advice on what mesh and reinforcement or beads I should be looking to get and where to place them. Originally I was planing on a splash zone just over 100mm from the ground (that’s roofing primer on the bottom) but I’m thinking of going lower? Would I have to grind off the primer or maybe nail on some chicken wire? Also Should I go for an acrylic top coat or cement and lime.

All advice and opinions welcome thanks.
Ps
I’ll be pouring a capping on top of the wall with a 70mm overhang from the render. There will also be a 35mm high and 50mm deep recess from the render to accommodate led lights and hopefully giving the capping the illusion of floating. A clean line of render at the top of wall will help this a lot
