Lime Render and Spray Cork in New Milton, Hampshire
From Exposed Brick to Frost-Finished Cork
If you own a brick property, you’ll know what a thankless job brick pointing can be. Repointing takes time, costs money, and never really feels like a permanent fix. For one homeowner in New Milton, Hampshire, it had become an ongoing frustration they simply didn’t want to deal with anymore. They also wanted something more from their home’s exterior: proper thermal insulation that would make a real difference to how warm and comfortable the property felt from the inside.
That's why we have been contacted. Over the course of two weeks, we applied a full exterior rendering system combining a breathable lime render base coat with CorkSol spray cork in the colour Frost (widely regarded as the most breathable rendering system on the market). The result? A beautifully finished, thermally improved home that will not need re-pointing ever again.
This case study walks you through exactly what was involved, from the initial challenge right through to the finished result, so you can understand whether a similar approach might be the right solution for your own property.
1. Lime Render and Spray Cork in New Milton Project Overview.
This was a detached single-storey bungalow in New Milton, Hampshire. Typical of many properties in the area, the building was constructed of red brick, which had served it well structurally but had begun to pose ongoing maintenance challenges for the homeowner.
At a glance, here’s what the project involved:
Location: New Milton, Hampshire
Property type: Detached bungalow (brick construction)
Duration: Two weeks
Base coat: Lime render (applied by Veramut Ltd)
Top coat: CorkSol SprayCork in Frost
System type: Breathable lime render base and spray cork system
Primary goals: Eliminate brick pointing maintenance and improve thermal insulation
2. The Challenge.
Like many brick bungalows across Hampshire and the surrounding area, this property had been showing its age. The mortar joints between the bricks were deteriorating, and the homeowner had already spent time and money on pointing repairs over the years. It was one of those jobs that keeps coming back. The frustration was completely understandable.
Brick pointing on a whole property is labour-intensive work, and even when it’s done well, it isn’t a permanent solution. Mortar will continue to erode over time, particularly on south- and west-facing elevations that are exposed to driving rain and temperature fluctuations. In Hampshire, where winters can be damp, and the wind off the south-west coast picks up, exterior wall maintenance like this can feel like a never-ending cycle.
On top of that, the homeowner had another concern: thermal performance. The brick walls, while solid, weren’t doing much to retain heat. The property felt cooler than it should in winter, and they wanted a solution that would genuinely improve the warmth inside (not just patch up the outside). So the brief was clear: find a rendering system that would permanently protect the walls, require minimal upkeep going forward, and actually make the home noticeably warmer.
3. The Solution: Lime Render and Spray Cork with CorkSol.
After assessing the property, we recommended a two-stage system that we felt was the ideal match for this particular build and the homeowner’s goals: a lime render base coat followed by CorkSol SprayCork as the finishing layer. Together, these two products form one of the most breathable, durable, and thermally effective exterior rendering systems available today.
Why Lime Render as the Base?
Lime render has been used in construction for centuries, and for good reason. It’s a naturally breathable material, which means moisture within the wall can escape rather than becoming trapped behind an impermeable coating. For a brick bungalow that has weathered for years, a breathable base is essential. Using a non-breathable system on a building like this risks trapping moisture within the wall structure, which can lead to problems such as spalling brick, rising damp, and internal moisture issues further down the line.
Lime render is also slightly flexible, which is important. Buildings move, not dramatically, but enough that a rigid render can develop hairline cracks over time. Lime accommodates natural movement far better than cement-based alternatives, making it a smarter long-term choice for older properties and solid-brick construction. Because we applied the lime render base ourselves, we could ensure the preparation was done correctly from the outset, giving the CorkSol top coat the best possible surface to bond to.
Why CorkSol SprayCork as the Finish?
CorkSol is widely considered the most breathable exterior wall coating on the market. It’s made from natural cork (a renewable, sustainable material) and is applied as a spray, giving an even, textured finish that looks distinctive and weathers beautifully. For this project, we used the colour Frost, a clean, light tone that immediately modernised the appearance of the bungalow and gave it a fresh, crisp look.
From a thermal insulation perspective, cork is an excellent performer. According to CorkSol’s own independent testing (carried out to the ISO 9867 standard), SprayCork has been shown to reduce heat loss through a wall by over 30%. CorkSol also state that their product is up to eight times more insulating than traditional lime or sand render alone. For the homeowner in New Milton, that kind of performance translated into a genuinely warmer home, with less reliance on heating during the colder months. [1]
Beyond insulation, CorkSol also offers:
Natural breathability - moisture can still escape the wall, preventing damp and condensation issues
Crack resistance - the flexible nature of cork means it moves with the building rather than splitting
Mould resistance - the coating creates an environment where mould struggles to establish itself
Weather resistance - it forms a robust barrier against driving rain, wind, and the kind of damp Hampshire winters this property regularly faces
Low maintenance - the surface can be cleaned with a domestic water jet, so there’s no specialist upkeep required
Eco-friendly credentials - cork is a natural, renewable material with a low environmental impact
Spray cork over lime render is a particularly effective pairing because both materials work on the same principle: they let the wall breathe. You get the structural protection and adhesion of lime render as the foundation, and the insulating, weatherproof, and aesthetic qualities of CorkSol on top. It’s a system that genuinely addresses all of the homeowner’s concerns in one go.
4. The Renovation Process.
The project ran over two weeks from start to finish, with our team working methodically around the full exterior of the bungalow. Here’s how it came together:
Step 1: Surface Preparation
Before any render goes on, the surface has to be right. We cleaned down the exterior brickwork thoroughly to remove any dirt, biological growth, and loose material from the joints. Any areas of brick that were structurally compromised were assessed and treated accordingly. Good preparation is the single most important factor in determining how long a rendered finish will last, so this stage is never rushed.
Step 2: Lime Render Base Coat Application
With the surface prepared, we applied the lime render base coat across all elevations of the property. The lime render was worked evenly to create a consistent, well-keyed surface that would accept the CorkSol spray without any issues. Lime render needs time to cure properly before a top coat goes on, so this stage requires patience. Rushing it risks adhesion problems down the line, which is why two weeks was the right timeframe for this project rather than trying to compress everything into a few days.
Step 3: Application of CorkSol SprayCork in Frost
Once the lime render base had cured sufficiently, we moved on to the CorkSol application. SprayCork is applied using specialist spray equipment, which allows for an even, consistent coverage across the full exterior. The Frost colour was chosen by the homeowner for its light, contemporary feel. It complemented the dark grey window frames and roofline beautifully, giving the property a clean, modern look while keeping it sympathetic to the surrounding neighbourhood. The spray process also meant that even the harder-to-reach areas and awkward corners were covered consistently, without the risk of uneven application you can sometimes get with hand-applied finishes.
Step 4: Finishing Touches and Inspection
With the cork coating applied, we carried out a thorough inspection of all elevations to ensure the finish was consistent, the edges were neat, and everything was exactly as it should be. The black plinth detail at the base of the walls was applied to give the property that sharp, finished edge that separates a good result from a great one. The site was left clean and tidy, which is something we take seriously. When the work is done, the only thing the homeowner should be looking at is the transformation.
Lime Render and Spray Cork in New Milton Project. Summary.
This exterior rendering in the New Milton, Hampshire project is a really good example of what the right rendering system can do for a property. What started as a frustration with ongoing brick maintenance became an opportunity to genuinely upgrade the home; its appearance, its thermal performance, and its long-term resilience.
The combination of lime render and CorkSol spray cork is one we recommend with confidence for brick properties, particularly older builds where breathability matters. It’s a system that works with the building rather than against it, and the thermal insulation benefits are real and measurable.
Here’s a quick recap of what was achieved:
Brick pointing has been eliminated permanently, no more ongoing maintenance costs
Thermal insulation significantly improved throughout the exterior walls
A fully breathable system installed from base coat to top coat
A fresh, modern Frost-coloured finish that transformed the kerb appeal
Crack-resistant and mould-resistant coating that requires very little upkeep
Completed on time within the two-week project window
If your home is a brick property and you’re tired of the same maintenance cycle, or if you’re simply looking to improve how your home looks and feels, exterior rendering with lime render and spray cork is well worth considering. It’s not a quick fix; it’s a proper, long-lasting upgrade.
