Acrylic & Sylicone Render

GET IN TOUCH

The HECK range of products, (formerly recognised under the Colfirmit Rajasil brand name), have an unrivalled track record in Europe and are becoming increasingly popular in the UK due to their superb quality, ease of application and superior colour range.

The flexible anti-crack formulation and ultra-violet resistant pigments of a silicone or acrylic render allow for large areas to be seamlessly rendered with perfect colour consistency.

In addition to being an excellent finishing coat for external wall insulation systems, Wetherby Silicone Renders are suitable for application onto thin coat or thick coat render-only systems.

The unrivalled versatility of WBS silicone and acrylic renders allows the products to be specified with confidence to transform virtually any substrate, giving dull and tired looking structures a new lease of life.
