RealCast Slab Panel 24×48 Flat — Medium Grey
The Slab Panel is a large-format concrete field with a flat or circle-cast face — the poured-in-place architectural concrete read, sized for open walls. Cast in fiber-reinforced lightweight concrete, no wet trades.
The Medium Grey colourway sits a shade cooler than Natural — even, mid-tone concrete with almost no warm cast.
Each box covers 48 square feet. Screws to the substrate through the built-in nailing flange — no adhesive, no wet trades. Panels lock together with a shiplap edge; cuts trim clean with a fine-tooth wood blade.
By design, colour and character vary. If needed, you can order a sample here: Medium Grey sample.
What sets it apart:
Large-format cast concrete face at panel-veneer weight — a 48×48 slab is under 40 lb; the real thing is 250+ lb and needs lift equipment. Poured-in-place look, screw-and-flange install. One quiet spec point: RealCast is cast with CSA cement rather than the standard Portland used across the field. CSA cement is shrinkage-compensating — the panels come out flatter and hold dimensional stability through the cure, so what leaves the mould matches what sits on the pallet. CSA cement production also runs up to 60% lower embodied CO₂ than Portland cement production, per the mill data sheet on file.
Good to know:
Best over a level substrate, with two people on the hang for the 48×48 — a large-format slab shows out-of-plumb from across the room. Fiber-reinforced concrete; cut wet with a respirator on. Tested to ASTM E84 — Flame Spread 0, Smoke Developed 0 (Class A results); Intertek report on request. Standard lead time is 3–4 weeks — the panel is cast when the order is placed.
