K Rend HP12 Base Coat is a high‑performance, polymer‑enhanced render designed to deliver exceptional adhesion, strength, and long‑term durability across a wide range of approved substrates. Its carefully balanced cement‑based formulation provides a dependable foundation for K Rend’s silicone thin‑coat and scraped‑texture finishes, ensuring that the final render system performs at its best in both residential and commercial environments.
Engineered for smooth, consistent application, HP12 offers excellent workability whether applied by hand or spray machine. Its enhanced flexibility helps reduce the risk of cracking, while its breathable structure supports healthy moisture movement through the building envelope—an essential factor in modern construction. Once applied, HP12 forms a robust, even surface that is easy to rule, straighten, and prepare for decorative top coats.
Ideal for new‑builds, refurbishments, and large‑scale façade projects, K Rend HP12 is trusted by professional applicators for its reliability, coverage efficiency, and compatibility with a wide range of finishes.
