Lime Plastering
TRADITIONAL METHODS
What is Lime Plaster?
Lime plaster is a traditional mortar used to coat internal walls and ceilings, commonly found in older and heritage buildings.
Unlike modern gypsum plaster, lime plaster is breathable, allowing moisture to pass through walls naturally. This helps prevent damp, regulates humidity, and keeps buildings healthier while maintaining their original character.

The benefits
Why use Lime Plaster?
Because lime plaster is ‘breathable’ and permeable, it is hugely beneficial for old buildings, allowing moisture to escape and evaporate, helping to prevent damp. We often see these damp problems commonly caused by a re-plaster with a modern gypsum plaster, or a non-breathable coat of emulsion, sometimes even wallpaper.
Solid, traditional built walls have no cavity to prevent the transfer of moisture, like there is in new builds, which makes it essential to allow the building to breath. Lime plaster not only allows breathability, but due to its high pH, it helps prevent moulds, helps to tolerate movement, and also regulates humidity by actively managing moisture.
Lime plaster is less brittle and less prone to cracking than other plastering materials, and requires no expansion joints.
