Render Coming Off The Wall

Seen below is an example of a render repair project - in this case the render is directly coming off. Cases like this are very rare and the reasons for it can be various. Realistically the reason the render is failing at this point does not matter - but repairing so it does not fail again does.

Does Patching Work

Repairing Cement Render can be done economically by patching existing but issues can arise with variations of new render meeting old render. It is important to understand that this can be visible when painting and in shades of sunlight.

When to patch render and when to redo

In some cases when the render is coming off comfortably the best remedy is to remove it all in a largely affected subsection. Below is a photo of a wall with all the old render removed. Usually cement render should come off in such fashion, more commonly the issues will arise in the forms of cracking and drumminess.


In summary there are two main options when it comes to repairing cement render fixing areas of concern by patching or fixing these areas and then reskimming the wall so that the render looks uniform across the whole wall.
