This exterior rendering system is designed to provide durable, weather-resistant, and aesthetically pleasing finishes on cement board substrates. The system starts with Unimix SF, a single-component cement-acrylic leveling compound that offers excellent adhesion, smooth application, and easy sanding for a flawless, shrink-free surface. A fiberglass mesh is then embedded to enhance flexibility and prevent cracking, followed by a second coat of Unimix SF to fully secure the mesh. The surface is built up with two coats of Unimix Render, a cementitious mixture for repairing and smoothing concrete and masonry surfaces, providing a solid and smooth finish suitable for painting or wallpaper, with the option to create a traditional textured look. Finally, NANOSIL Pro, a colorless, silicone-based water repellent, is applied to deeply penetrate the surface, protect against water ingress and alkalinity, and maintain the natural appearance of the substrate.
