Looking for some advice please for peeling paint on render

[B6653]

Looking for some advice please. This is the wall outside our house it was built and rendered about 20 years ago. It was left as brown render for a few years then we had the brain wave to freshen it up by painting it, we are now stuck in a never ending cycle of doom where we rub it down and repaint it only for the paint to bubble and eventually flake off, it's driving us mad. We had a professional opinion (brickie/builder) who said we should knock it down completely and start again unfortunately I'd have to sell a kidney to be able to afford what he quoted! We have been told that the wall is built using concrete blocks and this is why the paint bubbles and peels but the actual wall and render under the paint is sound and hasn't bubbled, peeled or cracked. Would it be possible to render over the existing render with a coloured render I know there are various ones or would we need to take off the old render and redo it all? Are there any types of colored render you'd recommend for this situation? Or alternatively another way around it? Thank you

That's because you didn't prime it, did you?

Thanks for your help. We were advised to prime it with a watered down PVA mix this doesn't seem to have made any difference. What would you recommend as a primer?

Sell other kidney
Hack off then new render

Looks pretty cracked to me. Garden walls have no protection from the weather, is over cladding it an option for you? Something you could do yourself?

Primer, is what I recommend. Primer. PVA indeed. Why the FCUK would you....oh never mind.

I use EB mix in Primer but it might be too late now youve gone and waterproofed the render. You'll have to read uo on how it handles none porous surfaces.

You have constant moisture.

It's coming from everywhere/all sides in a poorly designed and executed wall.

PVA is no good outdoors, sap told you that.



Depending on budget,


Both are throw money at a s**t wall,

1, scrape ALL existing paint, prime, fill and prep and finish in a proper mineral paint £££


2, Hack and render with a quality system. And THAT is another chat. ££££

One of those rare occasions when Steve talks some sense.
