Carbon N18
Near-black with real pigment depth. Most Carbon N18 installs end up on wet-rooms and walk-in showers or single feature walls behind joinery. Works as a backdrop to brass, gilt frames and warm-toned timber. In the Microcement range, Carbon N18 reads as the wet-room dark we get asked for most, built on an undertone that doesn't pick a side and warm black pigment. Borrows its character from high-contrast modern interiors and re-reads them in a modern context.

The wet-room dark we get asked for most reads its best where the light is soft and consistent. Below are the rooms we've installed this shade in most often.

Carbon N18 uses the standard Microcement build. The technical specification is the same across colour — only the pigment changes.
Questions clients ask about this shade
Won't Carbon N18 make the room feel smaller?+
Deep shades like Carbon N18 actually blur a room's edges, making walls feel further away rather than closer. The trick is to wrap the colour onto skirting and trim so there are no high-contrast lines to remind the eye where the room ends.
Is Carbon N18 suitable for a shower or wet-room?+
Carbon N18 can be specified for wet-rooms with our standard microcement wet-zone build: primer, two base coats with reinforcing mesh, two finishing coats, then a tanking membrane and two coats of polyurethane sealer. The colour itself doesn't change suitability — finish and sealer do.
What does Carbon N18 pair with from your range?+
We most often pair Carbon N18 with the three closest shades in its family — see the pairings panel below. Beyond that, pairs with marble, antique brass and richly grained timbers.
