Unlike traditional sand and cement finishes, K Rend and similar silicone-based systems are designed for long-term performance in the Welsh climate. These through-colour renders are water-repellent yet breathable, allowing moisture to escape from your walls while preventing new damp from entering. This is a critical step in reducing heat loss and solving issues related to cold wall treatment, helping you maintain a consistent internal temperature throughout the year.

We take the complexity out of property improvements by ensuring all our work strictly adheres to UK building regulations and PAS 2035 standards.
