Quick fix suggestions for external rendering coming away from wall

[LarryN]

Am selling house and have a problem with the rendering coming away from the wall in a position that is really obvious to anyone coming through the front gate to view the house. I can't afford to get someone in to re-do it, especially as we're moving out. I've attached pictures of the issue. Anyone got any good suggestions on how to in effect "glue" the existing render back onto the wall via the hole in the render so that I can then patch the hole?

I'm aware that it should be taken off and that once it's come away it usually can't be bonded back, but I'm really just looking for a very short-term cosmetic fix.

Thanks in advance.

You’re not going to be able to falsify that. Any attempt to do it will still be easy pickings for the surveyor to flag and likely to end up worse and looking like you’re trying to hide it. I’d just be honest from day one, let them have that and say it’s priced accordingly for a repair, which you can say is hundreds not thousands….

Thanks. Looking at it, if we were to get someone in to do it how much of the rendering would need to come off do you think. Can you just take off the patches where it has come away and re-render just those parts? I've never had it done, so have no idea.

Really hard to say tbh. If it was me (deliberately trying to cosmetic bodge) I’d gently take as much off as I could, leaving any bits I could get away with, then SBR it and patch it, but I do sand&cement rendering/know how to.

Risk with yours is without touching it no one knows how much is/isn’t sound.

Fwiw, looks like due to yours not being properly detailed at the top, water has just got behind it over time and blown it. Pretty sure once you start taking that top section off, a lot would come off before you hit anything sound. I’d just be up front and make it the buyers problem if you can’t part with a good few hundred to get it redone.

Wouldn’t harm to get a couple of quotes anyway though from decent local plasterers. At least then you know

Thanks. Well it was obviously the estate agents job to look at the house and what work needs doing and price accordingly. It was just whether there was any cosmetic fix to not put people off as the first thing they spot coming through the gate. As you say the surveyor would spot that the whole lot probably needs re-doing, but at least we'd be further down the line rather than someone looking and going "not interested".
