Microcement kitchen worktops: what to know before you commit
How microcement worktops actually perform around hot pans, red wine, lemon juice and oil — and the four specification details that decide longevity.

Microcement on a kitchen worktop is the most demanding application in the entire CimentArt range. It is also one of the most beautiful: a continuous, seamless run of stone-like surface that wraps the island, climbs the splashback and rolls up into a window reveal as one unbroken skin.
It is not, however, a material to specify casually. Here is what 20+ years of kitchen work has taught us about getting it right.
How it actually performs
- Heat: handles incidental contact (a kettle base, a warm dish). Always use a trivet for pans straight off the hob — same as you would on quartz or marble.
- Knives: the sealer is hard but cuttable. Always use a board.
- Red wine, coffee, turmeric: no staining when wiped within a few minutes; sealer is impermeable.
- Lemon juice, vinegar, descaler: the only real enemy — strong acids dull the sealer over time. Wipe spills promptly.
- Oil: sits on the surface, wipes off with warm soapy water.
The four specification details that matter
- Substrate. 22 mm WBP plywood, bonded and screwed to a rigid frame. Particleboard moves; microcement on moving substrate cracks.
- Mesh. Full fibreglass mesh in the base coat, lapped at every join. Non‑negotiable on worktops.
- Edge profile. Pencil-round or a soft bullnose — never a sharp 90°. Sharp edges chip on impact; rounded edges absorb it.
- Sealer. Two-component polyurethane food-safe sealer, four coats minimum, with a final week of cure before the kitchen goes into use.
Around the sink
Under-mounted sinks are entirely possible — the microcement wraps the cut-out and the sealer takes over from there. We always specify a 100% silicone bead at the sink-to-worktop join, refreshed every two to three years like any natural stone.
Cost
£350 – £500 per square metre supplied and installed in 2026, depending on edge detail, splashback wrap and substrate condition. Comparable with high-end quartz; cheaper than honed marble; not in the same conversation as laminate.
