When it comes to external wall insulation and render systems, the performance of the basecoat is critical.
It forms the backbone of the façade, providing strength, stability, and long-term durability to the entire system.
Fassa Bortolo’s MS 20.2 is a high-performance mineral basecoat mortar designed to deliver exactly that – reliability, versatility, and peace of mind on site.
MS 20.2 is a cement-based, polymer-modified basecoat developed for use within Fassa Bortolo’s fully tested FassaRend and EWI systems. Engineered for excellent adhesion and flexibility, it provides a robust substrate for reinforcement mesh and subsequent finishes, ensuring the façade performs as intended throughout its service life. Its carefully balanced formulation allows it to accommodate minor movements in the substrate, helping to reduce the risk of cracking and surface defects.
One of the key advantages of MS 20.2 is its adaptability across a wide range of substrates. Suitable for use on masonry, concrete, and insulation boards, it supports consistency across projects, simplifying specification and installation. When combined with Fassanet reinforcement mesh, MS 20.2 creates a strong, impact-resistant layer that enhances the overall durability of the façade system, particularly important in exposed or high-traffic environments.
From an applicator’s perspective, MS 20.2 offers excellent workability and ease of application. Its smooth consistency allows for efficient on-site handling, enabling installers to achieve uniform coverage and reliable embedment of reinforcement mesh. This not only improves finish quality but also supports productivity on site, helping projects stay on schedule without compromising performance.
MS 20.2 also plays a vital role in the long-term performance of rendered façades. By forming a stable, breathable base layer, it supports moisture management within the system while maintaining mechanical strength. This balance is essential in protecting the building fabric, improving resilience against weather exposure, and extending the lifespan of the external finish.
As part of the wider FassaRend system, MS 20.2 benefits from Fassa Bortolo’s extensive testing, technical expertise and system-led approach. Specifiers and contractors can be confident they are selecting a component that integrates seamlessly with compatible primers, finishes and reinforcement solutions.
Reliable, versatile, and performance-driven, FassaRend MS 20.2 is a basecoat that delivers strength where it matters most – making it a deserving Product of the Week for projects that demand long-term façade performance.
