Eco Rend K11 Key Coat Primer 25kg bag

Eco Rend K11 Key Coat Primer – 25kg Bag

Eco Rend K11 Key Coat Primer is a high-performance, polymer-modified primer specially designed to enhance the adhesion between substrates and render systems. Ideal for use in both internal and external applications, this versatile base coat is a vital first step in achieving a strong and durable render finish.

Product Features/Specifications:

This ready-mix primer comes in a 25kg bag and features a fibre-reinforced formulation for maximum bonding performance. Its light grey finish provides an optimal key for subsequent render coats, particularly when applied over smooth or low-porosity surfaces such as concrete or dense blockwork.

Detailed Product Benefits:

Eco Rend K11 Key Coat Primer improves substrate bonding, minimising the risk of render failure and ensuring a long-lasting finish. It regulates suction across the surface, providing a uniform base for further coatings. The product is reinforced with synthetic fibres and polymer additives that enhance flexibility and crack resistance, ensuring superior durability in varying environmental conditions. It also helps prevent de-bonding or delamination of renders applied on difficult substrates.

Applications and Versatility:

Perfect for use on a wide range of surfaces including concrete, blockwork, brick, and previously painted renders, Eco Rend K11 Key Coat Primer is particularly suitable for high-performance rendering systems. It is commonly used as a preparatory coat before applying Eco Rend K Mono or other monocouche and silicone-based renders. Whether on new builds or refurbishment projects, this primer supports excellent finish quality and application efficiency.
