Microcement with underfloor heating — Worthing specification
New-build clients in Worthing approaching microcement with underfloor heating do so on a two-year programme, not a two-month one. Our job is to slot cleanly between screed commissioning and second fix without extending the critical path. The Worthing catchment we work across covers BN11, BN12, BN13, BN14 — reached via the A27 South Coast Trunk Road, 22 min from brighton via the a27. Nearby coverage includes Goring-by-Sea (2 mi), Ferring (4 mi), Findon (4 mi). Site conditions matter here: coastal salt air on south-facing elevations. That shapes the primer and sealer specification below, not just the visible finish.
What to watch for on quote comparison
- ✕Firing the UFH before microcement cure — the finish crazes.
- ✕Missing substrate expansion joints — cracks telegraph through.
- ✕High-conductivity floor with a rug — creates a stress line at the rug edge.
- ✕Ambient-only cure — UFH schedules matter for both the screed and the microcement.
The spec sheet
Substrate and preparation
Microcement is one of the most UFH-compatible floor finishes on the market — 2 mm thickness gives fast thermal response and low resistance (0.02 m²K/W). But the screed must be commissioned to a slow heat-up schedule first, cracks resin-injected, and expansion joints honoured through the finish.
Detailing notes for your designer
A continuous microcement floor across a large open plan with UFH is the single most requested combination in modern-build interior design. Colour the microcement 1–2 shades darker than the joinery for the room to read as bright without going stark; sealer matt for domestic, satin for hospitality.
