Renders World provides the UK’s most advanced selection of professional silicone render systems, specifically engineered to withstand the demanding British climate. Our 2026 collection focuses on thin coat silicone render technology, offering a perfect balance between high-performance protection and aesthetic versatility. These hydrophobic render solutions are the industry standard for External Wall Insulation (EWI) and modern masonry projects, providing a flexible render finish that moves with the building to prevent cracking. With self cleaning render properties and high vapour permeability, these systems ensure a breathable, low-maintenance façade that remains algae-free for decades.
Key Benefits
Hydrophobic Protection: Water beads and rolls off the surface, significantly reducing dirt pick-up and staining.
Exceptional Flexibility: Polymer-modified structure prevents the surface cracking common in traditional sand and cement renders.
Vapour Permeability: A vapour permeable render that allows the building to breathe, preventing interstitial condensation.
Algae & Fungi Resistance: Advanced biocidal protection makes it the best render for UK weather in damp or shaded areas.
UV Stable Colours: Pre-coloured in over 1,000+ shades, eliminating the need for masonry paint and future maintenance.
EWI Systems: Optimized for use over Graphite EPS, Mineral Wool, and XPS insulation boards.
Substrates: Compatible with brickwork, blockwork, and rendering cement boards when used with a reinforced basecoat.
System Components: Must be applied over a dedicated exterior render primer to regulate suction and ensure adhesion.
System Integration: Works seamlessly with Atlas and Ceresit basecoats and fibreglass rendering mesh.
Limitations: Do not apply during frost, high winds, or direct intense sunlight.
Installation Highlights
Professional results require the application of a thin-coat layer matching the grain size of the selected render (e.g., 1.5mm). The substrate must be clean, dry, and primed with a colour-matched quartz primer to prevent the basecoat from showing through. For large elevations, ensure enough labor is present to maintain a "wet-edge," avoiding visible join lines. In winter conditions, we recommend using the Atlas Eskimo setting accelerator to manage drying times and protect the finish from early rain exposure.
Is This Product Right for Your Project?
Choose this product if: You require a premium, long-life finish (25+ years) that is crack-resistant and requires no future painting.
Consider alternatives if: You are working below the DPC (use mosaic renders UK for plinths) or on a restricted budget (consider acrylic render for less exposed areas).
Frequently Asked Questions
How many tubs do I need per square metre?
For a standard 1.5mm grain, the coverage is approximately 2.3kg – 2.5kg per m². A 25kg tub typically covers between 9m² and 10m² depending on substrate flatness.
Does it need to be painted?
No. These are "through-coloured" renders. The colour is integrated into the material, meaning it will not flake, peel, or require repainting like traditional masonry paint.
Can I apply silicone render in winter?
Yes, but you must monitor the silicone render application uk weather closely. Use a winter accelerator and ensure temperatures stay above 5°C during the initial 24-hour drying period.
