Last January a reputable looking plasterer I found on Check-a-trade re-rendered the back of my terrace house. The old render was cut off, a scratch coat applied and then rendered over.
I’ve finally got around to painting the back of the house but I’ve noticed that parts of the render, especially around frames, pipes and other joins, crumbles away quite easily. Other areas appear much more firmer, yet even these erode slightly when I lean a ladder up against them - leaving small, but noticeable nicks in the wall.
I’m guessing the either the mix ratio was wrong, too much plasticiser was used or the render dried out too quickly. The weather last January was unusually mild but also quite wet where I’m based in East Sussex.
The plasterer in question, after seeing photos, has acknowledged the problem. He’s away on holiday and can come and have a look towards the end of the month.
My question is whether I should push for all of the top render to be taken off and to start again? Or can what's there be repaired/strengthened? I’m not sure how sturdy/resilient new render should be, but a recently rendered wall down the end of my road appears to be rock-hard in comparison.
Any advice would be greatly appreciated.
