Applying monocouche scratch render onto concrete, clay, block, and brick substrate is relatively straightforward. However, you will require a specific set of materials to ensure it is completed correctly.
1. Priming the Substrate
One of the most effective ways to ensure your monocouche render system lasts is to prime the substrate properly. 
2. Applying the Monocouche Render and embedding the Mesh
When applying the render onto the primed substrate, you should apply it in two passes. Firstly, to a total depth of 10mm, avoid rendering monocouche below the DPC or within 150mm of ground level.
We apply the first pass with a spray pump Embeding a fibreglass mesh in the  pass, then we use a serrated edge  to create a mechanical key.
3 Following the mesh application, apply the second pass of monocouche render to a thickness of 8mm. Typically this is applied the next day. Once the monocouche render has nearly dried, it should be scratched back 2mm to give the final finish and a thickness of 6mm. Drying time varies depending on weather conditions. The total thickness of the finished monocouche render is approximately 16mm (10mm first pass and 6mm on the second pass).
