Durable Silicone Rendering for a Coastal Farmhouse Extension – Swanage, Dorset
At Measure Twice, we understand that homes in coastal locations face unique challenges. Salt-laden air, high winds, and fluctuating moisture levels can quickly wear down traditional materials. That’s why for this farmhouse extension in Swanage, Dorset, we selected a rendering system designed with durability in mind.
Our client needed a clean, long-lasting finish for their new extension—one that could handle the harsh coastal environment without constant upkeep. As a trusted building company in Dorset, our priority was delivering a solution that was both practical and visually appealing.
We opted for a silicone render system applied over cement board—a combination known for:
High breathability
Excellent weather resistance
UV stability and colour retention
Low maintenance
Silicone render provides a sleek, modern appearance, while its flexible nature makes it less prone to cracking, even with the natural movement of buildings in changing coastal conditions.
🛠️ The Process
Prepared and fixed cement board substrate to the new extension.
Applied a full silicone render system, including base coat, mesh, primer, and topcoat.
Finished with clean edges, ensuring the extension seamlessly blended with the existing farmhouse structure.
The final result is a sharp, weather-ready exterior that’s perfectly suited for the local environment, and built to last—both functionally and aesthetically.
