Case Study: Silicone Render Replacement in Portishead
Our client in Portishead contacted us to carry out a full silicone render replacement after the existing render on their external walls became stained, cracked, and weathered. Over time, issues such as cement render crack, uneven appearance, and discolouration had affected the property.
The Challenge – Silicone Render Replacement for External Walls
They were looking for a thin coat render system that would deliver a smooth, decorative and protective finish, suitable for coastal areas, fully breathable, and completely water repellent. The client also wanted clarity around material costs, long-term benefits, and whether silicone render is expensive compared with other types such as acrylic render, lime render, or cement based systems like K Rend.
Our Approach – Thin Coat Silicone Render Systems
We began by fully protecting windows, edges, driveways, and neighbouring surfaces to ensure a tidy and safe working environment. The rendering process started with the full removal of the existing render, followed by careful preparation of the surface to suit difficult substrates such as brick and cement backgrounds.
A polymer modified base coat was applied, reinforced with a full mesh layer for enhanced performance, durability, and greater flexibility. This thin coat system is specifically designed for external walls, offering improved resistance to cracking and long-term protection.
The final layer was a Chalk White silicone render, a ready mixed product with a fine texture finish. This silicone silicate render provides a decorative finish that is fully breathable, water repellent, and suitable for properties in coastal areas or conservation areas. The system can be spray applied or machine applied, depending on substrate and thickness requirements, and offers an extensive range of colour options, including Pantone colours.
The Result – Decorative and Protective Finish
The transformation was immediate. The property now benefits from a smooth, uniform appearance that enhances kerb appeal while protecting the wall structure beneath.
- The silicone render system delivers a durable, flexible, and protective finish
- The coloured render resists staining and maintains appearance over time
- The thin coat render provides a top choice alternative to paint or acrylic systems
- The finished surface is smooth, breathable, and visually consistent
The client was delighted with the quality, attention to detail, and how the new render system has completely refreshed the property.
The client left a glowing five-star review on Google…
“Sam and his team are well deserved of a five star review. They were conscientious and hard working in somewhat extreme weather conditions and ensured that we were informed of progress as they completed the work. The neighbours also remarked on how courteous and polite they were. The house has been transformed by the quality of their work.”
