I have a cottage with a natural stone wall in an arid climate that sees rain only in the winter.
The wall is really nice to look at:
The stones were collected from the area, and attached to the wall with cement. However, it appears that when the cement dried, it shrunk, and left many small holes in between the stones.
Apparently as a consequence, there is water damage on that wall inside:
It appears that the wall isn't completely watertight, and rainwater is coming through.
I bought the house only recently, so I do not know whether this is the damage from one winter, or from ten.
Still, something needs to be done because this corner is the only one that can house the wardrobe.
The only way to fix this that I can see right now is to plaster the wall. However, the thought breaks my heart because I'd of course be destroying its beauty.
Is there a way to water-proof a natural stone wall while preserving its look?
