Can ecorend SF15 be spray applied?
Yes. ecorend SF15 can be applied by both spray and hand application, depending on site requirements and grain size. Spray application can significantly improve productivity on larger façades while maintaining a consistent finish.
Is ecorend SF15 BBA certified?
Yes. ecorend SF15 forms part of a BBA approved system (Certificate 18/5592) and complies with BS EN 15824:2017, ensuring verified performance and suitability for UK construction standards.
What is the difference between silicone-acrylate render and acrylic render?
A silicone-acrylate render like ecorend SF15 Sil-Flex combines silicone technology with acrylic resins, delivering a highly flexible, anti-crack finish with enhanced water repellence and improved breathability compared to standard acrylic renders.
Traditional acrylic renders are durable and easy to apply, but are typically less breathable and offer lower long-term moisture management, which can impact façade performance over time.
This makes silicone-acrylate systems like SF15 a more advanced, balanced solution, providing greater flexibility, weather resistance, and long-lasting protection for modern façades.
How weather-resistant is ecorend SF15?
ecorend SF15 provides a weather-resistant protective layer with low water absorption (W3 classification). This helps protect façades from rain, wind, and environmental exposure while maintaining appearance over time.
What finishes can be achieved with ecorend SF15 Sil-Flex Thin Coat Render?
ecorend SF15 Sil-Flex Thin Coat Render delivers a consistent textured thin coat finish, typically achieved using a plastic float and producing a natural, modern façade aesthetic suitable for residential and commercial projects.
What is the difference between silicone-acrylate render and silicone render?
A silicone-acrylate render like ecorend SF15 Sil-Flex combines silicone technology with acrylic resins to create a highly flexible, anti-crack finish with excellent weather resistance.
While fully silicone renders focus on maximum breathability and self-cleaning properties, silicone-acrylate systems provide a balanced solution, offering durability, movement tolerance, and cost-effective performance.
This makes SF15 an ideal choice for reliable, long-lasting façade finishes on standard applications.
Does ecorend SF15 use recyclable packaging?
Yes. ecorend SF15 is supplied in fully recyclable packaging, supporting sustainability targets and reducing environmental impact on site.
