Final Thoughts

Rendering your house is more than just a cosmetic upgrade—it's a long-term investment in your property's durability and energy performance. While traditional renders like cement and lime still have their place, modern options like silicone and monocouche are taking centre stage for their low-maintenance and weather-resistant properties.

Tip: Always choose a renderer familiar with the material you select. The best render applied poorly won’t perform well.
