Render patching

[Starbars123]

Hi all, I've got some really deep render patching, I'm talking about 4 inches deep in places,the areas are about 5m2 each, I need to tank the area first because of severe water damage and these patches are about 15 ft up.
how would you go about it and what mix would you use, cheers.
