Its innovative formulation combines the robustness of cement with advanced polymers, resulting in a base coat that adapts seamlessly to the unique characteristics of different surfaces. This flexibility ensures a reliable and durable bond, crucial for achieving a flawless rendering finish.

Unrivalled Adhesion

One of FX4’s key strengths lies in its superior adhesion properties. This product establishes a robust bond between the substrate and the subsequent render coat, providing a foundation for a long-lasting and visually appealing finish. The exceptional adhesion ensures that the render remains securely affixed, even in challenging conditions.

FX4 boasts W2 weatherproofing capabilities, offering a formidable shield against the elements. This ensures that your surfaces remain protected from rain, wind, and temperature fluctuations, maintaining their structural integrity and aesthetic appeal over time.

Breathability for Longevity

Our one coat base provides high breathability, which allows the substrate to release moisture, an essential feature for preserving the structural integrity of the underlying surface. This quality not only guards against potential moisture-related issues but also contributes to the long-term durability of the finish.

Efficient Application Methods

With the utilisation of cutting-edge trowel technology, and ready-to-use formula, FX4 can be applied effortlessly by hand or spray and can be brush-keyed finished as required. This user-friendly aspect streamlines the application process, allowing for precise and efficient coverage. Whether applied manually or with a spray system, FX4 ensures a consistent and professional result.

Ideal for Advanced Systems

FX4 is particularly well-suited for use in External Wall Insulation (EWI) systems and render carrier board systems. Its flexibility and exceptional adhesion make it a crucial component for these advanced rendering systems, ensuring a high-quality and enduring finish.

The unparalleled flexibility, adhesion, weatherproofing performance, and ease of application of our one coat base ensures it is a great choice if you’re looking for an excellent base product.
