We specialise in lime pointing for traditional masonry using high-quality lime mortar, based on either lime putty or natural hydraulic lime (NHL). Our lime mortars offer significant advantages over cement-based alternatives, ensuring your masonry not only looks great but also remains protected for years to come.
Lime mortars are softer and more porous than cement mixes, allowing moisture to evaporate more easily from the joints. This helps reduce moisture levels in the walls, minimising the risk of soluble salts accumulating on the stone surface, and preventing the damage (or ‘spalling’) that often occurs with more rigid cement mortars.
Our skilled team ensures the best possible results by carefully managing the drying and suction process, which is essential for any lime-based work. We take the time and care needed to ensure your property’s masonry is preserved in top condition.
Our Comprehensive Lime Pointing Process
Preparation
We start by thoroughly preparing the masonry. Any defective pointing is raked out to a depth equal to twice the joint width (but no less than 20 mm), ensuring the joint profile is square. Our team uses precise tools, like plugging chisels, to avoid damaging the stone or brickwork.
Damping
Before applying the mortar, we dampen the joints after brushing out any loose material. This prevents smearing on the stone or brick surface and ensures maximum compaction and minimal shrinkage of the mortar.
High-Quality Premixed Lime Mortar
We offer high-grade premixed lime mortars for your convenience. These are ready for immediate use, eliminating the need for extended preparation. For traditional lime putty mortars, we recommend pre-mixing them for a few weeks, but with our service, you can count on using a perfectly prepared mix.
For exposed or damp conditions, we can also enhance the mortar with pozzolan to increase compressive strength and frost resistance, tailored to the specific needs of your property.
Pointing and Finishing
We begin at the top of the wall, carefully applying the mortar using specialised tools to avoid shrinkage. Whether you prefer a flush or recessed finish, our team delivers results that are both structurally sound and aesthetically pleasing.
Once the mortar is “green hard” (firm but still workable), we brush the joints to expose the coloured aggregate, giving the pointing a natural, attractive finish.
Protection and Aftercare
Lime pointing requires protection from the elements during the curing process. We use hessian cloth to shield the fresh work from sun, rain, wind, or frost if work is carried out in colder months.
We also provide tailored advice for specific conditions, such as exposed elevations or chimney stacks, to ensure your masonry remains protected in all weather conditions. If needed, we can treat the mortar with linseed oil to improve water repellency or apply vapour-permeable water repellents for additional protection.
Expert Guidance and Support
We are committed to delivering top-quality service while ensuring the best possible care for your property. Our team can advise you on all aspects of lime pointing, from selecting the appropriate materials to ensuring the work is carried out to the highest standards. We also offer detailed guidance on specialised areas, such as window and door frames.
Our services come with a promise of quality, and we ensure every project meets the unique needs of the building and its environment.
