Description
Atlas Eskimo Setting Accelerator 0.25kg – Winter Rendering Additive
Product Overview
The atlas eskimo setting accelerator 0.25kg UK is a high-performance polymer additive engineered to eliminate site delays during the UK’s challenging winter months. This ready-to-use liquid enables the safe application of thin-coat renders when substrate and air temperatures are near freezing (above 0°C) and humidity levels exceed 80%. By accelerating the polymer cross-linking process during water evaporation, it delivers 3x faster early rain resistance and cuts setting times by half. A critical component for Part L 2025 compliant accelerator UK installations, this additive ensures that professional facade projects remain on schedule without compromising the final structural strength or aesthetic uniformity of the render finish.
Key Benefits
- Double Setting Speed: Reduces the critical curing window by 50%, allowing for faster project completion in damp conditions.
- Rapid Rain Shield: Provides rain resistance up to 3 times faster than untreated renders, preventing costly washouts.
- Low-Temperature Capability: Enables application at temperatures as low as 0°C, extending the rendering season through late autumn and winter.
- High Humidity Performance: Specifically designed to function in environments with humidity levels exceeding 80%.
- Structural Integrity: Initiates preliminary cross-linking without affecting the breathability, flexibility, or final hardness of the system.
- Pre-Mixed Convenience: Supplied in a precise 0.25kg dose for easy site integration with standard 25kg tubs.

Application & Compatibility
- Compatible Systems: Exclusively for use with ATLAS silicone, silicone-silicate, silicone hybrid, and SILKON BA thin-coat renders.
- Ideal Use-Case: Critical for winter accelerator for thin-coat renders UK applications where overnight frost or unexpected rain is a risk.
- Substrate Scope: Suitable for all EWI-grade basecoats including Atlas Hoter U and Ceresit ZU.
- Note: Not suitable for use with mineral renders, traditional monocouche, or thick-coat sand and cement systems.
Installation Notes
Atlas Eskimo must be added directly to the render tub immediately before application and mixed thoroughly using a low-speed mechanical stirrer to ensure even distribution. Do not alter the dosage; one 0.25kg bottle is calibrated for a single 25kg tub. It is essential to monitor the local 24-hour weather forecast; while the accelerator handles near-zero temperatures during application, the system requires a minimum of 18 hours of cure time above 0°C to achieve full stability. Protective measures (such as scaffolding netting) are still recommended in extreme coastal exposures.
Is This Product Right for Your Project?
- Choose this product if: You are rendering in the UK between October and March, or working in coastal areas with consistently high humidity and a high risk of sudden rain.
- Consider alternatives if: Temperatures are consistently above 15°C and humidity is below 60%; in these standard conditions, the render will cure naturally without additives.
Frequently Asked Questions
Does adding Eskimo change the colour of the render?
No. When used at the correct dosage of 0.25kg per 25kg tub, the additive is chemically neutral regarding pigment stability and will not cause discolouration or "patchiness" in the final finish.
Can I use two bottles to make it set even faster?
No. Increasing the dosage beyond the manufacturer’s specification can cause the render to become brittle or affect the workability (open time) on the wall. Stick to the 1:1 ratio.
Does this allow me to render in a frost?
The air and substrate must be above 0°C at the time of application. The accelerator protects the render after it is on the wall, allowing it to survive temperature drops only after the initial 18-hour curing period.
