Lime plaster has been used throughout traditional British buildings for centuries. Unlike many modern plaster systems, lime is particularly suited to older solid-wall properties because it allows moisture to move through the building fabric and evaporate naturally.
At Nordic Damp Proofing, we provide specialist lime plastering services for period, heritage and traditionally constructed properties, including walls affected by damp, failed modern plaster and previous inappropriate repairs.
Whether we’re restoring an individual wall following damp treatment or undertaking more extensive work within an older property, we assess the existing construction before specifying the plaster system.
The aim is simple: use materials that work with the building rather than against it.
Lime plastering involves applying a lime-based plaster system to internal walls and ceilings, particularly within traditionally constructed buildings.
Many older properties were built with solid brick or stone walls and originally finished using lime plaster. These walls manage moisture differently from modern cavity-wall construction.
Lime plaster is relatively vapour-permeable, allowing moisture within the wall to evaporate through the surface rather than becoming unnecessarily trapped behind a dense finish.
It is also more flexible than many hard modern materials, making it well suited to historic buildings that experience small amounts of natural movement.
When correctly specified and applied, lime plaster provides an attractive traditional finish while remaining compatible with the underlying building fabric.
Before plastering begins, we assess the wall construction, existing finishes and overall condition of the substrate.
Where damp has been present, we also consider moisture levels and the underlying cause. Applying new lime plaster before addressing an active source of moisture is unlikely to provide a lasting solution.
Loose, damaged, salt-contaminated or inappropriate plaster can be carefully removed where necessary to expose the underlying brickwork or stone.
This gives us an opportunity to assess the masonry itself and properly prepare the surface before the new lime system is applied.
Successful lime plastering depends heavily on preparation.
We clean and prepare the underlying masonry, address loose material and ensure the surface provides the appropriate background for the new plaster system.
Where masonry repairs or repointing are required, these can be addressed before plastering proceeds.
Different buildings require different specifications.
We select an appropriate lime plaster system according to factors such as the wall construction, masonry condition, moisture levels, location and required finish.
Rather than applying the same specification to every property, the plaster build-up is considered as part of the overall building.
Lime plaster is generally built up gradually rather than treated like a modern single-coat finishing product.
Depending on the specification, multiple coats may be applied to create the required depth and finish while allowing appropriate curing between stages.
Particular attention is given to corners, junctions, openings and transitions between different materials.
Once the final coat has been applied, the surface is finished according to the required appearance.
We also provide advice regarding drying, ventilation and subsequent decoration.
Lime needs to cure correctly, so homeowners should avoid attempting to accelerate the process unnecessarily with excessive heat.
We remove unsuitable or failed wall finishes where required, prepare the underlying masonry and install a lime plaster system appropriate for the property’s construction.
Lime plastering can be undertaken as an individual restoration service or form part of wider works involving damp treatment, masonry repairs, lime mortar repointing or heritage restoration.
Our approach is based on the condition of the actual building rather than assuming that every old wall requires the same treatment.
Traditional buildings need to be able to manage moisture.
Older solid walls were commonly constructed using permeable materials such as brick, stone and lime. These materials can absorb moisture and subsequently release it as conditions change.
Historic England explains that traditional permeable construction allows moisture to be absorbed and later evaporate from surfaces. Introducing impermeable materials can alter this behaviour and increase the risk of moisture accumulation.
This is one reason why material compatibility matters when repairing older buildings.
Lime plaster can help retain the vapour-permeable characteristics of a traditional wall while providing a durable internal finish.
The process starts by assessing the wall and establishing why the existing plaster has failed.
If there is an active moisture problem, we investigate this first. That could include penetrating damp, defective external pointing, high ground levels, plumbing leaks, condensation or another source.
Once the wall is suitable for restoration, failed finishes are removed where necessary and the masonry is prepared.
The appropriate lime plaster system is then applied in stages, with sufficient curing between coats, before the surface receives its final finish.

One of the most important times to consider the type of plaster being used is after a damp problem has been identified.
Moisture can carry soluble salts through masonry and into existing plaster. As moisture evaporates, these salts can remain within the wall finish and continue attracting moisture from the surrounding air.
Simply skimming over heavily contaminated or deteriorated plaster can therefore result in staining or deterioration returning.
Before replastering, we assess:
This allows the plaster specification to form part of the wider solution rather than becoming another cosmetic repair.
The correct choice depends on the building.
Gypsum plaster is widely used in modern construction and can provide an excellent smooth finish in appropriate circumstances.
However, it does not behave in exactly the same way as traditional lime plaster.
Lime is generally more vapour-permeable and flexible, which can make it particularly suitable for traditional solid masonry walls.
This doesn’t mean every old property must have every piece of gypsum removed. Existing materials should be assessed according to their condition and whether they are actually contributing to a problem.
Where we’re restoring a traditional wall, our priority is compatibility with the existing building fabric rather than automatically applying a modern plaster specification.
You may often hear older properties described as needing to “breathe.”
The term can be misleading because walls do not literally breathe.
What matters is the ability of the building fabric to manage moisture.
Traditional lime-based materials can allow water vapour to move through the wall and moisture to evaporate from surfaces. This can help prevent excessive moisture becoming trapped within the masonry.
For this reason, lime plaster often forms part of a wider moisture-management strategy for older properties alongside appropriate pointing, external maintenance, drainage, heating and ventilation.
Older properties have often undergone several generations of renovation.
It isn’t unusual to uncover traditional stone or brick walls that have subsequently been covered with cement render, gypsum plaster or other modern finishes.
These materials aren’t automatically responsible for damp simply because they’re modern.
However, where an impermeable finish is restricting evaporation or has become damaged through moisture and salt contamination, removing it may form part of the restoration process.
We assess the existing materials and determine whether they can remain or whether replacement with a more compatible lime system would benefit the building.
Lime plaster is particularly associated with historic and listed buildings, where retaining original materials and character is important.
Repairs to listed buildings should be approached carefully.
Existing historic plaster should generally be retained wherever practical rather than unnecessarily removed simply to create a perfectly uniform modern surface.
Where replacement is necessary, the new work should be sympathetic to the original materials, texture and appearance.
Depending on the building and extent of the proposed work, Listed Building Consent may also be required. This should be established with the relevant local planning authority or conservation officer before applicable alterations begin.
If you have an older property with crumbling plaster, recurring damp patches, salt contamination, damaged wall finishes or inappropriate previous repairs, book a survey with Nordic Damp Proofing.
At Nordic Damp Proofing, we’re pleased to offer damp, mould, and timber surveys to homeowners and landlords. In some cases, fees may apply for more detailed reports — but don’t worry, our team will always let you know beforehand.
Submitting this form doesn’t commit you to a survey. One of our friendly team members will contact you within 24 hours to discuss your enquiry and confirm whether a survey is needed. Once booked, we can usually arrange a visit within 24 hours of confirmation.
