HourWall Urban Concrete Panel 24×48 ½" Circles — Onyx

Urban Concrete is an interior-only panel with an architectural poured-concrete face — cast in high-density polyurethane, chosen for feature walls in commercial retail and modern residential interiors. Available in 24×48 and 48×48 panels with a flat or circle-cast face and either ½" or 1" depth.

The Onyx colourway is a deep saturated near-black — architectural, moody, and unmistakably concrete.

Each panel covers 8 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: Onyx sample.

What sets it apart:

Poured-concrete face without the pour or the weight — a 48×48 panel is roughly 18 lb; real GFRC is 250+ lb per panel. Interior-only; that's the trade for panel-speed install.

Good to know:

Interior use only. Best for interior feature walls in commercial retail and modern residential rooms — the pattern is tight, so cuts land on a joint cleanly. Five-year interior warranty (Quality Stone runs twenty years exterior/interior; RealCast is ten).
