Hi Jeds & r896neo, Thanks for your comments. The shuttering used when pouring the concrete section of the wall resulted in a fairly rough, well keyed surface so I simply wet this down prior to applying the scratch coat. I think I am beginning to learn that detailing is the key to...

Hi Tony, Thanks for your reply. The render is on a concrete block wall, however, the bottom 1 meter of wall is solid concrete (a poured concrete footing that is adjacent to a patio). I have rendered the block wall and concrete wall down to the patio level. There is no dpc, this is...
