SF15 Sil Flex 25KG

The SF15 Sil-Flex 25kg is a high-performance silicone acrylate resin-based thin coat render designed for long-lasting protection, flexibility and durability on external masonry and External Wall Insulation (EWI) systems. Formulated with advanced silicone technology, SF15 provides excellent anti-crack performance, superior weather resistance, and a highly water-repellent yet breathable finish - making it ideal for UK external wall applications.

Available for same-day collection in Ecorend colours, making SF15 Sil-Flex one of the fastest supply silicone thin coat renders in the UK.

This ready-to-use thin coat render can be applied by hand or spray and typically achieves 8-10m� coverage per 25kg tub, depending on substrate and grain size. Its flexible formulation accommodates minor building movement while helping to prevent cracking and moisture ingress, ensuring a durable and attractive fa�ade finish.

🎨 In-Store Tinting Available - Ready Within Minutes
Choose from the full Ecorend colour range, tinted in-store for fast, same-day application. Tinting ensures perfect colour matching between your render and primer/basecoat while reducing project delays.

For best results, apply SF15 over a prepared substrate using SFP15 Sil‑Flex Primer 20kg , which can also be tinted in-store to match your render colour. The primer balances substrate suction, improves adhesion, and ensures a uniform, long-lasting finish.

This fast tinting service ensures colour accuracy and consistency while reducing lead times compared to factory-ordered finishes.
