Lime & Your Home

Breathe Again

A common misconception of the term ‘Vernacular Construction’ is that is only refers to listed and protected buildings and homes. However Vernacular refers to any building or home that was made via Solid Wall Construction, this type of construction is very common, particularly in Wales (34% of Building Stock).

Cottages, Churches and Farm Houses are the most commonly selected as an example of solid wall construction, however there is a larger proportion of terraced houses built this way. ALL of which require lime to be used either for Restoration, Renovation &/or Conservation.

Lime is a breathable material opposed to cement which isn’t; lime takes in moisture and simply ‘breathes’ it out again. This creates a continual cycle that keeps the building healthy, however once cement is rendered or pointed on top of it, that cycle of ‘breathing’ has instantly stopped. As soon as any moisture gets behind the cement (which is inevitable) it stays there.

The common problem(s) once cement has been either rendered or pointed or a ‘Modern’ Paint has been applied onto a Solid Wall Buildings;

– The trapped water washes out the lime mortar in-between the stone/brick; this will affect the structural integrity of the building.

– Cement is harder than most stone and brick, the water is channelled into the softer stone/brick which will delaminate, corrode and/or even fall out.

– Because the moisture can’t leave the wall, the wall stores a massive build up of water. This presents itself as DAMP.

– Cold, buildings tend to stay colder because of the excessive moisture in the walls.
