Render finishes

Monocouche render

Monocouche render is a one-coat, through-coloured cement-based render applied 15–20mm thick, usually by spray, and scraped back to an even textured finish. It's widely used on new blockwork, extensions and sound masonry.

Where is monocouche used?

Monocouche is best on new or sound blockwork and brickwork with consistent suction — extensions, new builds and garden walls. It's applied thicker than thin-coat renders and scraped once firm to reveal the texture.

Typical build-up

Thickness: 15–20mm
Finish: Scraped texture, through-coloured
Substrate: Blockwork or sound masonry
Application: Spray or hand
Over insulation: Not used

Can monocouche go over insulation?

No — insulation systems use a mesh-reinforced base coat and a thin-coat finish instead. If you want insulation as well as a new finish, see insulated render.

Why does monocouche sometimes look patchy?

Colour variation (often called shading) can appear if it's applied in poor weather, on walls with uneven suction, or in sections on different days. Working an elevation in one go in suitable conditions keeps the colour even.
