Ceresit CT 74 Silicone Render White 1.5mm – Self-Cleaning Facade Finish
Product Overview
Professional-grade ceresit ct74 silicone render white 1.5mm UK is a high-performance, stone-textured decorative finish engineered for both External Thermal Insulation Composite Systems (ETICS) and traditional masonry. Formulated with advanced silicone resins, this self-cleaning render for UK weather UK delivers exceptional hydrophobic properties, ensuring that elevations remain resistant to dirt accumulation and driving rain. Designed for long-term facade protection, CT 74 combines high vapour permeability with structural elasticity, making it the definitive choice for breathable wall systems. The integrated BioProtect formula provides a robust shield against fungal, algal, and mould colonisation, maintaining a pristine brilliant white finish in even the most damp UK environments.
Key Benefits
- Exceptional Self-Cleaning: High resistance to dirt ensures the facade remains clean through natural rainwater rinsing.
- Superior Breathability: High vapour permeability allows moisture to escape, preventing dampness within the building fabric.
- BioProtect Technology: Specialized formula actively guards against the growth of algae, fungi, and mould.
- Impact & Crack Resistance: Enhanced elasticity compensates for thermal stress and mechanical impact across varying climate conditions.
- UV & Colour Stability: Advanced pigments ensure the brilliant white tone remains vibrant without yellowing over time.
- Fast-Track Application: Optimized for both manual application and professional machine spraying for large-scale site efficiency.

Application & Compatibility
- System Integration: Primarily recommended for use within Ceresit ETICS systems using graphite EPS or mineral wool.
- Substrate Versatility: Compatible with even, properly prepared surfaces including concrete, traditional plaster, gypsum, and chipboard.
- Required Priming: Must be applied over a cured layer of Ceresit CT 16 quartz primer to ensure chemical bonding and suction control.
- Note: Do not apply on horizontal surfaces or areas with permanent moisture exposure (e.g., ground-level splash zones without proper plinth protection).
Installation Notes
Substrates must be structural sound, dry, and primed at least 24 hours prior to rendering. Ceresit CT 74 must be mixed thoroughly with a low-speed stirrer to reach a uniform consistency. To prevent visible join lines (lap marks), elevations should be completed in a single "wet-on-wet" operation, requiring sufficient site labour to maintain the edge. Avoid application during direct intense sunlight, high winds, or when rain is forecast within the first 24 hours. In UK winter conditions (+5°C to 0°C), always consult our technical team regarding the use of setting accelerators.
Is This Product Right for Your Project?
- Choose this product if: You require a premium, low-maintenance finish for a coastal or high-pollution urban area where self-cleaning and breathability are critical requirements.
- Consider alternatives if: You are working on a plinth or house base; in these high-impact areas, we recommend using a specialized mosaic render for better mechanical protection.
Frequently Asked Questions
What is the coverage for a single tub?
One 25kg tub covers approximately 9.5 to 10 square metres for a 1.5mm grain. We recommend adding 5% extra for site waste and detailing work around windows and reveals.
Does this render need painting?
No. Ceresit CT 74 is a through-coloured render. The white pigment is integrated throughout the mass, so it will not peel or flake like masonry paint.
Is CT 74 breathable?
Yes, it is classified as V1 (High) vapour permeability. This ensures that moisture from within the walls can escape, which is essential for the long-term health of UK properties.
