System No. 1148
Polymer Enhanced Cementitious Render
This system combines a high-quality, ready-to-use cementitious render with a clear, solvent-based silicone water repellent for durable, decorative surface finishing. The cementitious layer repairs and levels uneven areas, achieving a hard, smooth finish with strong adhesion and water resistance — and can be applied up to 2 cm thick in one layer without cracking. It is ideal for creating decorative or colored finishes, including antique-style effects. The protective silicone treatment deeply penetrates the substrate to repel rain, CO₂, and dust while maintaining breathability and the natural appearance. Together, the system extends surface life and reduces maintenance needs under harsh conditions. Suitable surfaces include concrete, cement plaster, blockwork, fair-faced concrete, brickwork, lime sandstone, and natural stone.
