Everything you need to know about EWI-090 Monocouche Scratch Render

Derived from the French and meaning ‘single layer,’ Monocouche Render is a modern, single-layer render that offers a low-maintenance, weather-resistant, aesthetic stone-like finish. 

The EWI Pro Monocouche Render is available in six colours; Bright white, Cotton white, Latte, Cashew, Pebble, and Portobello. The render is suitable for use on many surfaces such as concrete, clay, block and brick substrates. Ideal for use on both commercial and residential projects.  

The material base comprises of premium quality Portland cement, hydrated lime, polymers and modifying admixtures. Delivering enhanced adhesive properties, ensuring a flexible and crack-resistant finish. EWI-090 is a low-maintenance product providing a long-lasting decorative finish. 


Before applying the EWI Pro Monocouche Render, you should ensure that all surfaces are clean, dry and free from any materials that may impair application. Make sure to prime the substrate, if in doubt we recommend using the EWI-310 Universal Primer.  

The EWI-090 is a 25kg dry mixture that should be combined with approximately 4.5-5 litres of clean, potable water. Mix thoroughly for around 2 minutes, leave to stand and then remix to ensure the consistency is uniform. 


The EWI Pro Monocouche Render can be applied either manually or by machine.  

 Once all preparation is completed to a high standard, apply the render to the primed surface in two passes to a total depth of 17mm. Then, scratch back to roughly 15mm – Ensure to avoid rendering below the DPC or within 150mm of ground level as this can let moisture inside the rendered wall.  

 Apply the first pass with either a stainless steel trowel or, alternatively, apply with a spray pump. Embed a layer of Orange Fibreglass Mesh into the first pass to help strengthen the install. Then, apply the second pass to a thickness of 9mm. Then scratch back to achieve the decorative finish.  

 Drying times can vary depending on weather conditions. We always recommend rendering in conditions between 5-25°C.
