Hi all

I see a lot of these small garden walls nowadays are rendered - at least I think they are.

Are they not at risk of spalding?

Ha - must’ve either made up a word or have it totally arseways.

When you have flat horizontal rendered surfaces - no capping. And water, cold, freeze, expand and contracts busts all the render off.

How does this not seem to happen on garden walls. My neighbour pointed the issue out to me ( I thought that was the word he said) I see it everywhere now.

Spalling—sometimes incorrectly called "spaulding" or "spalding"—is the result of water entering brick, concrete, or natural stone. It forces the surface to peel, pop out, or flake off. It's also known as flaking, especially in limestone.

Every painted wall is another future weekend ruined.

Ah - thank you. I wasn’t far off at all.

I presume it also applies to render on a flat block wall.

And I presume that all these modern looking garden walls will eventually spall and look awful.


And my final presumption is that they should be capped to prevent this from happening.

Is there anyway that you can render only without it spalling?

I reckon the only way to reduce the "cracking" effect is to
Plaster the walls without using the preformed angle beads and edges as these create a a hair line point for water to get in behind the plaster.
Best practice would be to render using reveal laths.

Very interesting. Now you say it, those walls that I spot in the locale which have spalled all have that beading.
