Traditional Lime Plastering in Swindon

The Failure of Modern Plasters in Historic Homes

Many property owners in Swindon face a relentless battle with dampness, peeling interior decorations, and a cold internal atmosphere. Often, the blame is incorrectly placed on the age of the building or the proximity to the canal. In reality, the true cause is almost always the legacy of modern renovations. Historic buildings were constructed to act dynamically with their environment; their solid masonry walls naturally absorb moisture and evaporate it harmlessly. However, when 20th-century tradesmen applied rigid, waterproof gypsum plaster to the internal walls or Portland cement to the exterior, they completely sealed the building. This impermeable barrier traps ground moisture and daily household condensation within the core of the wall. Over time, this trapped water destroys the historic lime mortar, rots embedded timbers, and creates severe interior dampness. At Longnor Heritage, we rescue historic properties by carefully hacking off these suffocating modern materials, exposing the original masonry, and allowing the building to finally dry out.

Reinstating Traditional Breathability

To permanently cure damp and restore the structural health of a period property, we must return to the traditional materials it was designed to work with. Our master craftsmen are specialists in the application of genuine lime plaster, a highly porous material that acts as a natural poultice, actively drawing moisture out of the walls. We do not use modern chemical quick-sets; instead, we rely on the slow, natural process of carbonation. We employ a historically accurate three-coat system, beginning with a robust scratch coat that is heavily reinforced with natural animal hair. This essential addition provides immense tensile strength, allowing the plaster to flex seamlessly with the seasonal movements of the historic structure. Following a meticulous curing period, the float coat is applied to level the surface, deliberately preserving the organic, uneven charm that defines true heritage interiors. Finally, a skim coat of pure lime putty is applied, creating an elegant, smooth finish perfectly suited for breathable mineral paints.
