Hi,
My father in law has built me a new flowerbed (me being far too cack-handed for bricklaying), but it has been built with aerated blocks.
I intended to render the top and outward-facing walls of the bed in any case, however I am concerned that the extreme porousness (if that is a word) of the aerated blocks will lead to the render deteriorating very quickly.
Is there anything I need to be doing to the inward-facing wall to waterproof it before I chuck in the loam mix? If so what? Or are my fears misplaced?
thanks
