Concrete can be made to read convincingly as timber — grain, edge detail and all. This technique comes from William B. Carlisle Design, who has built several wood-grain concrete countertops and shared the method. It combines casting against a mould, sand-blasting to raise the grain, and three acid stains brushed along it.
Note on results: every photo here is a real Direct Colors customer project. Acid stain is reactive and every countertop mix behaves differently, so test on an offcut or a hidden section before you commit — on a surface this small and this visible, it matters more than anywhere else.
Casting the top
1
Reinforce the cabinetry — a concrete countertop can weigh up to 900 lb
2
Build the form from melamine or resawn lumber, biscuited and glued, clamped until dry
3
Take a silicone mould cast off the lumber edges to capture the edge grain
4
Mix countertop mix in a 5-gallon pail — one gallon of water per 50 lb, added in quarters, blended at least 10 minutes with a hand mixer and birdcage paddle
5
Spray a thin layer over the whole mould first for full coverage — this is what prevents pinholes
6
Fill the rest of the mould and let it cure
7
Demould, then sand-blast the surface to bring the wood grain up

Staining the grain
This is where it becomes wood rather than textured concrete. Three colors, brushed along the grain rather than across it, lightest first.
8
Mist the surface with water before staining
9
Dilute the acid stains 2:1 with water — Malayan Buff, Cola and Coffee Brown for this look
