I`m currently building a concrete block pond .
I`ll be rendering the internal walls next , prior to painting .
Just wondered if its possible to use 1 coat of render as long as the walls are flat , or does it have to be 2 coats .
Also , what is the minimum thickness required ?
Any advice would be a great help
