I have a garage built with concrete blocks and the walls are surrounded on the outside by a layer of concrete rendering.
The problem is that large cracks have built up in the rendering over time, probably as there are no expansion joints anywhere.
I'm considering what might happen in the winter if water/ice gets into/behind these cracks and starts to make some of the rendering fall off.
I was going to paint over the cracks, however is there a better way than this that I can preserve the current state of the rendering?
(P.S.: I'll post some pictures if it helps)
