So, we look at our process Here at MH Restoration, when we look at lime pointing. unlike traditional pointing which is still highly used with Sand and cement, time scale of the two are really different and what you can do in one day, in terms of M2.
when we give our clients the quote we also include time frames. now time frames when looking for the best outcomes you have to choose wisely on your service provider.
so, Taking your time when doing lime pointing is crucial for several reasons, as it involves a meticulous process that directly impacts the longevity, appearance, and structural integrity of the masonry. Here are some key reasons why patience and attention to detail are important:
1. Proper Bonding with Stone or Brick
Lime mortar (as opposed to modern cement-based mortar) is more flexible and breathable, which is particularly important for historic or older buildings. If you rush the pointing process, you might not achieve the right bond between the mortar and the stone or brick. Properly mixing and applying lime mortar allows it to adhere to the surface correctly, ensuring that the pointing not only fills the joints but also strengthens the overall structure.
2. Avoiding Cracking or Shrinking
Lime mortar needs to cure slowly, and rushing the application or working too quickly can cause it to shrink, crack, or dry unevenly. This is especially true in warmer weather where the mortar might dry too quickly if not applied at the correct pace. Taking your time ensures the mortar sets and hardens properly without compromising its strength and flexibility.
3. Achieving the Right Finish
Lime pointing often involves creating a smooth, uniform finish that blends well with the surrounding masonry. Rushing the process can result in an uneven finish, visible gaps, or mortar that doesn't match the aesthetic of the original structure. By working carefully, you can create a seamless, professional appearance that enhances the overall look of the building and preserves its historic character. Homes espcecially can often be to rushed.
4. Preventing Mortar Overfill or Uneven Joints
When pointing, it's important to avoid overfilling the joints or leaving them too shallow. Rushing through the work may lead to inconsistencies in the depth of the mortar, which can affect both the appearance and durability of the masonry. Properly filling and shaping the joints ensures a neat, even appearance and better long-term stability.
5. Allowing for Proper Curing
Unlike cement mortar, lime mortar requires slow curing, which means you need to allow it to set and hydrate gradually over time. This process is delicate and can be easily disturbed if you work too quickly or don't give the mortar enough time to settle and harden properly. A rushed job can lead to problems with bonding and overall durability.
6. Maintaining Breathability
One of the key benefits of lime mortar is its ability to allow moisture to evaporate through the masonry. If you don't take your time to apply lime pointing correctly, you risk sealing the masonry too tightly or preventing proper airflow. This can lead to trapped moisture inside the walls, which may cause damage like mold or decay in the long term.
7. Preserving the Historic Integrity
For historic buildings or conservation projects, it's essential to follow traditional techniques and take your time to ensure the pointing matches the original work in terms of material, color, and finish. Rushing the pointing process on a historic building can alter the building's character and reduce its value, so patience is key to preserving its authenticity.
8. Enhancing Durability and Weather Resistance
When done properly, lime pointing can last for many years, its been proven in Historic Builds, providing weather resistance and helping to protect the masonry from the elements. If the pointing is done too quickly or incorrectly, it could wear down prematurely, leading to costly repairs down the line. Taking the time to ensure every detail is correct will result in a more durable, long-lasting finish.
In short, lime pointing is a craft that requires patience and expertise to ensure the right balance of aesthetics, functionality, and durability. Taking your time allows the lime mortar to bond correctly, cure slowly, and provide the best possible results for your Brick or masonry project.
