K Rend

K Rend is a high-quality silicone render system that provides a durable, weatherproof, and aesthetically refined finish to exterior walls.

Its clean appearance, wide colour range, and durability make it one of the UK’s most trusted external rendering systems.

What is K-Render?

K Render is a polymer-modified render that is formulated to bond firmly to exterior walls. Here, it forms a weather-resistant and breathable layer. Manufacturers incorporate silicone technology to ensure the product creates a hydrophobic surface, allowing water vapour to escape, and thereby preventing moisture ingress.

The K Render system differs significantly from traditional sand and cement mixes and requires minimal maintenance. Its flexible finishes are available in a range of K Rend colours, including bright white and soft natural tones. All products are through-coloured, meaning the pigment runs through the entire mix, so the surface doesn’t necessarily require painting.

What is K Render used for?

K Rend is used on a variety of substrates to improve wall protection and aesthetics. It is ideal for:

• New builds and refurbishments that need a smooth, decorative façade.
• Masonry and blockwork surfaces that require breathable weather protection.
• Homes or commercial buildings where long-term colour and finish are desirable.

The system’s functional protection and decorative appeal make it suitable for an extensive variety of architectural styles.

Types of K-Rend

K Rend products come in a broad selection of mixes and finishes, each tailored for varying substrates and application methods.

The most popular include:

K-Rend base coat

• HP12 and HP14 base coats – Reliable preparatory layers that level walls and boost adhesion before the top coat. They ensure strong adhesion and smooth surface preparation.
• HPX base coat – Flexible polymer formulation designed for mixed or challenging substrates.

K-Rend finishing coat

• K1 spray render – Pre-mixed, machine-applied render for rapid installation. It produces a consistent surface texture.
• TC15 thin coat – A silicone-enhanced top coat offering superior water repellence. It gives sleek, contemporary aesthetics.

K Rend GP mortar

• GP render – General-purpose hand-applied render that is suitable for traditional masonry.

Each component integrates within the render system to ensure compatibility, robust adhesion, and a long-lasting exterior.

Benefits of K Render for external wall

K Rend provides these benefits for modern façade systems:

• Weather and crack resistance for lasting exterior protection.
