Traditional Lime Plastering in Hammerwich

The Damage Caused by Waterproofing

Living in a traditional rural property in Hammerwich offers immense charm, but it often comes with the frustration of persistent dampness and cold internal walls. In almost every pre-1919 property, this damp is not a failure of the original architecture, but the direct result of mid-20th-century renovations. During this period, the construction industry embraced fast-setting, impermeable materials like cement render and modern gypsum plaster. While excellent for modern homes, these materials are devastating to solid masonry. When a historic solid wall is smothered in rigid, waterproof gypsum or cement, its natural ability to breathe is suffocated. Ground water and everyday household condensation hit this impermeable barrier and become permanently trapped within the core of the wall. This leads to the rapid decay of historic lime mortar, the rotting of structural timbers, and the growth of toxic black mould indoors. Longnor Heritage arrests this cycle of decay by expertly stripping away these harmful layers, allowing the historic masonry to breathe and safely evaporate the trapped moisture.

The Craftsmanship of Haired Lime Putty

Working with traditional lime putty is a time-honoured craft that requires patience, skill, and a deep understanding of historical building physics. Our master plasterers tailor the lime mix specifically to the needs of your Hammerwich property. For internal restorations, particularly over traditional wattle and daub or riven oak laths, we utilize a historically accurate three-coat system. The initial scratch coat is heavily infused with natural horsehair. This provides vital flexibility, ensuring the plaster can move in harmony with ancient timber frames or shifting masonry without cracking—a feat that rigid modern gypsum cannot achieve. Once the scratch coat has fully carbonated by absorbing carbon dioxide from the air, we apply the float coat. This layer levels the wall while intentionally maintaining the charming, uneven character typical of historic properties. The final skim coat provides a visually soft, elegant finish that perfectly complements period interiors while restoring the vital capillary action of the walls.
