ecorend proudly introduces the BBA Approved SR365 Ultimate Silicone Thin Coat Render. Engineered with meticulous precision, SR365 redefines industry standards for hybrid silicone render systems. Tailored to meet the exacting demands of our customers, this through coloured, all-year thin coat render is designed to excel in any environment.

Advanced Silicone Render Formulation

SR365 incorporates cutting-edge silicone polymers, setting a new benchmark for exterior rendering. This advanced two component, dispersion based formulation delivers a superior finish that seamlessly combines aesthetic appeal with unmatched resilience against the elements.

All Year Application – Render in Temperatures as Low as -5°C

The versatility of SR365 is evident in its suitability for year-round application. Whether faced with the rigours of winter or the challenges of summer, SR365 maintains consistent workability and curing times, offering contractors unrivalled flexibility in project scheduling.

Easy to apply even in temperatures from +25°C down to -5°C, and in humidity of up to 99%, it offers applicators a unique ability to continue projects throughout the seasons.

Rainproof Hydrophobic Barrier

SR365’s silicone-rich composition provides a hydrophobic shield, rendering it inherently water-resistant. It is rainproof in just 2 hours at temperatures above +5°C and is rated W3 (Low) on water absorption. This property ensures effective moisture management, safeguarding the underlying substrate from potential damage due to dampness and water ingress.

Enhanced Vapour Permeability

While offering robust protection, SR365 remains breathable and flexible, allowing moisture vapour to escape. This breathability is crucial in preventing issues such as trapped moisture and condensation, which can lead to cracking and structural degradation over time.

Substrate Versatility

SR365 Ultimate Silicone Thin Coat Render is specifically engineered for exceptional adhesion across a broad spectrum of substrates. From traditional masonry and robust concrete to an assortment of commonly used construction materials, SR365 stands as a versatile rendering solution suitable for an extensive range of architectural projects. Its seamless application ensures a consistent, high-quality finish, regardless of the underlying surface.

This adaptability not only simplifies material selection but also instils confidence in contractors and specifiers, knowing that SR365 can reliably enhance the performance of various building types and structures. Whether for residential, commercial, or industrial applications, SR365 is an ideal choice for achieving a flawless, long-lasting exterior finish.

Low VOC Content

With an impressively low VOC (Volatile Organic Compounds) content ranging from 0.3 to 7.99%, this render minimises its environmental impact. This commitment to reducing VOC emissions not only benefits the environment and creates a cleaner, more breathable atmosphere within and around the structure, but also ensures a safer and healthier space for occupants and workers alike.

SR365 Ultimate Silicone Thin Coat Render represents a significant advancement in silicone render systems, offering enduring quality regardless of the season.  For detailed technical specifications, please refer to the SR365 Technical Data Sheet.

SR365 stands apart due to its two-component hybrid silicone formulation, delivering enhanced durability, flexibility, and performance in challenging conditions. Key differentiators include:

  • All-year application from -5°C to +25°C, even in humidity up to 99%
  • Rainproof in just 2 hours (above +5°C), minimising weather delays
  • Highly vapour permeable, helping prevent trapped moisture and condensation
  • Low VOC formulation, supporting healthier environments
  • UK manufactured using premium quality materials, ensuring strict quality control
  • Sustainability-led production, with 100% recyclable packaging and over 90% of raw materials locally sourced, reducing environmental impact and transport emissions

This combination delivers a reliable, contractor-friendly system designed for real on-site conditions – not just lab performance.

Yes, SR365 is part of a BBA approved system (Certificate 18/5592), providing confidence in its tested performance and suitability for UK construction projects.

Unlike traditional silicone renders, one of the key advantages of SR365 is its ability to be applied in temperatures as low as -5°C and humidity up to 99%, making it ideal for winter working conditions and reducing downtime on site. It is also rain resistant in just 2 hours at temperatures above +5°C.

SR365 is highly vapour permeable (V2 classification), allowing moisture vapour to escape while preventing water ingress. This balance helps reduce the risk of trapped moisture and condensation build-up.

SR365 provides superior durability due to its hybrid silicone technology, offering:

  • Flexibility to accommodate movement, reducing chances of any cracking
  • Water resistance (W3 classification) to protect against driving rain
  • Strong adhesion and long-term façade protection

A silicone thin coat render with all-weather capability, such as SR365, is one of the most efficient options. Its ability to be applied in low temperatures, high humidity, and unpredictable weather makes ecorend SR365 ideal for UK site conditions all year round.

SR365 is specifically engineered for contractor efficiency, offering:

  • Extended working windows across varying temperatures, allowing you to apply render in the winter months
  • Fast rain resistance to minimise delays
  • Consistent workability and predictable setting times

This allows contractors to maintain programme schedules year-round.

Yes, SR365 can be applied using suitable conveyor spray equipment, although it is typically finished by hand using a plastic float to achieve the final texture. Gravity-fed or battery-operated spray systems are not recommended for optimal performance. For further advice on suitable spray equipment, please contact our technical department.

ecorend SR365 Ultimate Silicone Thin Coat Render delivers a uniform, textured thin coat finish. It is applied and finished using a plastic float to create a consistent, contemporary scraped appearance suitable for both residential and commercial façades.

The through-coloured formulation ensures a consistent colour across the entire surface, eliminating the need for painting and reduces long-term maintenance.
