Also known as through colour render or scratch render, Monocouche render is an excellent rendering system that can be applied to most masonry substrates*. It is both breathable and water resistant and requires little in the way of maintenance as it is a coloured render, coming in up 30 different colour varieties depending on the render manufacturer.
Monocouche render is a mineral based through coloured cement or lime based render that would require both a primer and alkaline resistant mesh incorporating into the system with it.
