About Monocouche Scratch Render

Our EWI-090 Monocouche Scratch render is a decorative render that can be hand applied or applied by spray machine. The monocouche render comes as a dry mix, so it requires mixing with water (5.5 litres) prior to application.

Our monocouche render should have a minimum life expectancy of 10 years when applied correctly – not only does it enhance the look of the property, it also provides a long lasting weatherproof barrier. Once installed, our monocouche scratch render is virtually maintenance free.

The render is available in 18 incredible colours and the product is suitable for both new-build and refurbishment projects.

Applying EWI-090 Monocouche Scratch Render

Normally the monocouche render is applied in two passes, the first pass should be 9-10mm and a fibreglass mesh is normally embedded within this first layer of the render, to provide additional strength and flexibility. The second pass of monocouche scratch render is then applied on top of the first layer. The thickness of the second pass should be 8mm, taking the total thickness of the render coat to 18mm.

To ensure you get the full benefits of the polymer modified properties of the render, ensure the first layer is not completely dry before applying the second layer of render, so chemical bonds can form between the first and second pass.

Once the monocouche render has gone off, a render scratch float is used to create the desired texture – this involves scratching back the surface of the render by 2mm, giving a final thickness of 16mm.

Application Conditions

  • If the original substrate does not have a suitable mechanical key to render onto, an artificial key must first be created.
  • Should not be applied in rain or humid conditions, or if wet weather is expected before the render has set.
  • Should not be applied in cold weather if any of the materials – or the substrate- are frozen, or if there is any risk of frost damage within the first 24 hours.
  • Should not be applied in temperatures above 30°C.
  • Will reach optimal strength after 28 days.
  • For professional use only.

Coverage Rates

1 x 25kg bag of the Monocouche render will cover approximately 1m2 (when taking the render coat to a total thickness of 18mm before scratching back).

  1. Rated 5 out of 5

    Used K-rend previously, but this scratch render sprays on great, good trade discount and arrived the next day.

  2. Rated 4 out of 5

    This scratch render product is a good product on the spray machine. Had a small job I priced in north-west London, which I decided to use the EWI Pro scratch render. Went on fine with two passes. Only reservation was that the next day, the delivery came in the afternoon when I was expecting it earlier, so my guys were sitting idle.

  3. Rated 5 out of 5

    Good value Monocouche render. Went into store and got pickup price, so much better than price advertised. We use K-rend, Weberpral-m and Monorex all the time and this stuff is easily on a par with it.
