Lime pointing allows the building to breath. It also draws moisture away from the stones.

Problems occur when attempts are made to seal the building with modern materials.

Stones move, by microscopic amounts, from season to season. These movements send stresses across the wall causing hairline cracks in cement pointing and cement render. These cracks act like little pumps, drawing in water. If it can’t escape, the water will build-up over time.
It will find its way to the base of the building and damp patches will appear on the interior. Further water build-up will saturate the lime mortar within the wall, causing the stones to compress down and, in-turn, cause more stresses up the wall. If the water freezes, the stones will crack and break apart. Whole sections of wall could be pushed out. If the building is rendered with cement this will also crack and fall out.
