Atlas Gemini RS Silicone Render White 25kg – Premium BBA Certified Finish

Product Overview

Professional-grade atlas gemini rs render white 25kg UK is an advanced, fibre-reinforced silicone finish engineered for elevations requiring the highest levels of structural durability and aesthetic precision. As a premium for professionals BBA certified UK system component, Gemini RS utilizes a unique 4K aggregate formula to deliver exceptional adhesion and rapid texturing. Designed specifically for the high-exposure environments of the UK, it features "Mirror Effect" technology to protect white pigments from UV degradation and "Biosec" encapsulated biocides for long-term resistance against biological growth. This 1.5mm grain render is the definitive choice for high-traffic commercial zones and luxury residential projects where impact resistance and self-cleaning performance are mandatory.

Key Benefits

• 3D-Flex Technology: The highly flexible, fibre-reinforced matrix compensates for extreme thermal stress and prevents micro-cracking during UK freeze-thaw cycles.
• Mirror Effect Protection: High light reflectance technology protects polymer resins and white pigments from destructive UV rays, ensuring long-term colour stability.
• Biosec Bio-Protection: Controlled-release "capsule" technology provides unmatched resistance to algae, mould, and lichen colonisation.
• Clean Technology: Advanced siloxane hydrophobisation creates an airtight surface structure that repels dirt and allows for natural self-cleaning during rain.
• 4K Aggregate Formula: A proprietary blend of four texturing aggregates ensures superior tool adhesion and reduces product waste on-site.
• High Mechanical Strength: Engineered for maximum impact resistance, making it ideal for schools, parking areas, and pedestrian gateways.

Application & Compatibility

• System Integration: Optimized for use within certified ETICS systems using graphite EPS boards and mineral wool slabs.
• Substrates: Compatible with all properly prepared mineral substrates including concrete, traditional cement-plasters, and fibre-cement boards.
• Mandatory Priming: Must be applied over a cured layer of Atlas Cerplast to ensure chemical bonding and regulate substrate suction.
• Project Scope: Specifically recommended for elevations exposed to high industrial pollution or heavy greenery.

Installation Notes

Substrates must be clean, structurally sound, and primed at least 24 hours prior to application. Atlas Gemini RS should be mixed thoroughly with a low-speed mechanical stirrer to achieve a consistent mass. To eliminate the risk of join lines (lap marks), maintain a "wet-edge" and complete entire elevations in a single continuous operation. During autumn or winter installations, the use of a professional setting accelerator is highly recommended to protect the fresh render from early rain. Avoid application during direct intense sunlight or high winds, which can lead to premature drying and surface tension.

Is This Product Right for Your Project?

• Choose this product if: You are seeking a premium, BBA-certified white finish with maximum resistance to impact and biological growth for a high-end facade.
• Consider alternatives if: You are working on a low-exposure, budget-sensitive domestic project where standard silicone renders may meet your requirements.

Frequently Asked Questions

How many tubs do I need for a 100m² elevation?

Assuming a standard 1.5mm application, 10 tubs of Gemini RS will cover 100m². We recommend ordering 11 tubs to allow for window reveals and site detailing.

Can this render be applied by machine?

Yes. The 1.5mm 4K aggregate structure is specifically optimized for professional rendering units, providing high speed and a uniform finish on large-scale elevations.

Does it require maintenance?

While the "Clean Technology" facilitates self-cleaning, we recommend a soft-wash hose down every 2-3 years to remove heavy atmospheric deposits and maintain the hydrophobic properties.
