EWI-090 Monocouche Render

The EWI-090 Monocouche Render is a high-performance cement-based, through-coloured scratch render. This decorative render has been designed with water-repellence, breathability, and durability in mind. The EWI-090 is used on both larger commercial or residential projects, and suitable for concrete, clay, block, and brick substrates.

Monocouche Scratch Render is a thick coat render that is applied in two passes. The material base is comprised of premium quality Portland cement, hydrated lime, polymers and modifying admixtures. This delivers enhanced adhesive properties, ensuring a flexible and crack-resistant finish is achieved.

The EWI-090 is a low maintenance product that achieves a natural stone-like appearance for a long-lasting decorative finish.


All surfaces should be clean, dry and free from material that may impair application. Prime the substrate before application. We recommend the EWI-310 Universal Primer.

The EWI-090 Monocouche Render is a dry mixture, mix with clean, potable water to activate the ingredients. Pour the 25kg dry mix bag into approx. 4.5-5 litres of water. Mix thoroughly for 2 minutes, leave to stand, and then re-mix.

Monocouche Render Application

Apply render to the primed surface in two passes to a total depth of 17mm and scratched back to 15mm. Avoid rendering below the DPC or within 150mm of ground level.

Apply the first pass with a stainless steel trowel or spray pump. Embed fibreglass mesh in the first pass. Then, apply the second pass to a thickness of 9mm. Drying time varies depending on weather conditions.

    Used K1 in the past, but this product seems comparable and is cheaper. Quick delivery too.
