Monocouche Render

Updated: Jan 12, 2023

What is Monocouche Scratch Render?

Monocouche render is a decorative, through-coloured render. As opposed to the thin coat renders which have different grain sizes and come ready to apply, the monocouche render is a thick coat render normally applied to a finish thickness of 15mm and comes as a dry mix – so it requires mixing with water before application. Monocouche can be applied either by hand or by machine application.

Most monocouche renders are breathable, therefore allowing water vapour to escape through the render.

What is the difference between Thin coat & Monocouche?

The main difference between Thin coat and Monocouche is there appearance,

monocouche is a pitted, sandstone type of texture, whereas thin coat has more of a synthetic look.

Cost can also be a difference as a typical monocouche application is very fast due to only being one coat. The application of the Thin coat systems are usually a three stage process, Stage 1: Preparing the substrate with a base coat render, this has to fully cure before the next stage can take place.

Stage 2: Apply a priming coat and let dry for 24 hours.

Stage 3: Apply the Thin coat render.

Typical cost of Monocouche rendering

Most rendering companies would usually price rendering on a square metre rate, you can expect to pay £60 upwards per m2, supply and installation, depending on how many square metres your project is.

The square metre price doesn't take into consideration any additional preparation work, i.e. Removal of old render, Base coats before new render can be applied, scaffolding costs, waste disposal etc.
