CB26_PUM_E_SP

CB26 Pumice is a textured Carbon Black GRC with a striking blue undertone. Its pumice finish keeps the natural air voids from casting, creating a porous, volcanic-looking surface. A light acid etch softens the face further, giving a dry, matte, mineral feel that is full of shadow and depth.

The mix pairs fine dolomite sand with white cement and an intense blue pigment balanced with black, producing a dark navy-black that reads differently with every change in light. With a Light Reflectance Value (LRV) of 10.99%, the finish emphasises its dramatic depth and textured character, creating a powerful interplay of light and shadow across the surface. An impregnating sealer penetrates the surface and the voids, protecting against dirt and moisture without filling in the texture.

Made as Glass Fibre Reinforced Concrete (GRC) at 12–18mm, CB26 Pumice is lightweight enough for feature walls, ceiling panels, column cladding, reception desks and statement furniture. Its texture brings an organic, architectural quality to retail and hospitality spaces. For a coordinated scheme, the same colour can be specified in a smoother finish for counters or floors.

The blue in CB26 can be made richer or more subdued, and the colour can be matched to RAL, Pantone or brand references. Pumice texture depth can also be specified. All panels are made to order in the UK, and the mix can be adapted to include recycled glass or reclaimed aggregates, adding a further sustainable layer to this distinctive textured finish.
