SMET NHL 3.5 binder was specially selected for the restoration of this old stone Irish cottage by GF Roofing. Old stone cottages are part of the character of the Irish landscape, and they need materials that suit how they were built. For this renovation of a stone cottage in Ireland, GF Roofing Ltd chose SMET NHL 3.5 as the binder for the lime mortar.
Our superior-quality pure Natural Hydraulic Lime binder SMET NHL 3.5, produces a superior-quality lime mortar for repointing and internal restoration. NHL binders’ selective hydraulic strength development makes them particularly suitable for producing lime mortars for masonry work, rendering, and plastering on historical buildings and monuments.
Historical restorations in Ireland are essential for maintaining the country’s architectural heritage and cultural identity. These projects require a delicate balance between preserving historical authenticity and incorporating modern sustainability practices. Through careful planning and execution, Ireland’s historic buildings can be conserved for future generations to appreciate and enjoy.
Traditional solid stone walls absorb moisture and release it again. Modern cement-heavy mortars are hard and dense, and they trap that moisture. Over time it can cause damp, spalling stone and failed joints. A natural hydraulic lime mortar is softer and more vapour permeable. It lets the wall breathe and move with the seasons, and it fails in the mortar joint rather than the stone, which is much easier to repair.
SMET NHL 3.5 is a pure natural hydraulic lime binder produced to EN 459-1. It gains strength steadily as it sets, which makes it a good fit for repointing, rendering and plastering on traditional masonry. On this project, GF Roofing Ltd used it for repointing the internal stonework to bring the cottage back into good condition.
The result is a cottage that is weathertight and sound but still looks like an old stone building, not a modernised one. It is a good example of what can be achieved when masonry work is done sympathetically.
Why choose NHL for old buildings?
- Breathable mortar that allows moisture exchange between the wall and its surroundings
- A sympathetic, repairable alternative to cement and gypsum-based products, which are less vapour permeable
- Well suited to conservation, restoration and ecological new-build projects
NHL binders, available directly from SMET and online or in-store via our distribution partner Haldane Fisher, are particularly suited for ecological new builds, conservation, restoration, and preservation works.
