Why lath and plaster
Lath and plaster is a traditional construction technique used before the widespread adoption of drywall. Thin strips of wood (laths) are nailed horizontally to wall studs or ceiling joists and spaced slightly apart to allow plaster to squeeze between them, creating a strong mechanical bond.
Lime plaster is then applied in several layers over the lath and squeezed through the gaps hardening to form a rigid, durable surface.
Installing and repairing lath and plaster requires specialised skills, which our expert craftspeople have perfected over a number of years, to achieve stunning results.

Lath and Plaster Benefits
Breathability and Moisture Management
Similar to lime wash, traditional lime plaster is breathable, allowing moisture to move through the walls and preventing the build-up of dampness. This is especially important for older buildings that may not have modern damp-proofing.
Authenticity and Historical Accuracy
For historical buildings, maintaining the original construction methods is essential for preserving the property’s authenticity and historical integrity. If lath and plaster is true to the building’s original construction, maintaining that historical value is important, and often required under planning requirements.
Durability and Repairability
Properly maintained lath and plaster walls are highly durable and can last for centuries. They are also more easily repaired in small sections compared to drywall, which might require replacing whole panels.
Aesthetic Appeal
Lath and plaster offers a unique, rich texture that contributes to the character and aesthetic of older properties. The finish is often more nuanced and visually interesting than the flat surfaces of drywall.
Fire Resistance
The plaster layers provide a good level of fire resistance compared to drywall, which can be crucial in older buildings that may not have other modern fireproofing measures.
