Microcement Floors: The Complete UK Homeowner's Guide

Microcement has exploded in popularity among UK homeowners seeking that coveted polished concrete aesthetic. But what exactly is it, how much does it cost, and is it right for your home?

What Is Microcement?

Microcement is a thin polymer-modified cement coating that can be applied over most existing surfaces. It creates the appearance of polished concrete but at just 2–3mm thickness — making it ideal for renovations where floor height is critical.

Unlike poured concrete, microcement is:

• Applied by hand — giving each floor a unique, artisan character
• Waterproof when sealed — perfect for bathrooms and wet rooms
• Compatible with underfloor heating — no thermal mass issues
• Incredibly versatile — floors, walls, worktops, and even showers

Microcement vs Polished Concrete

How Much Does Microcement Cost?

For a typical UK home installation:

• Floors: £90–£140 per m²
• Walls: £80–£120 per m²
• Wet rooms (floors + walls): £100–£160 per m²

A 20m² bathroom complete with microcement floors and walls typically costs £3,000–£5,500 including preparation and sealing.

The Installation Process

Day 1: Preparation

We assess and prepare your existing surface. This may include priming, levelling, and applying a fibreglass mesh to prevent cracking.

Day 2–3: Application

Two coats of microcement are applied by hand using specialist tools. Each coat is allowed to set before the next. The technique and pressure used create the subtle variations that give microcement its character.

Day 4: Sealing

Two coats of polyurethane sealer protect the surface and provide water resistance. We offer matt, satin, and gloss finishes.

Day 5: Ready

Light foot traffic after 24 hours. Full use after 7 days.

3. Wipe spills promptly
4. Re-seal every 5–8 years for continued protection

Frequently Asked Questions

Does microcement crack?

Hairline micro-cracks can appear and are generally considered part of the material's character. Proper preparation with fibreglass mesh minimises structural cracking.

Can I install microcement myself?

We strongly advise against DIY installation. Microcement application requires considerable skill and experience to achieve a smooth, even finish.

Is microcement suitable for underfloor heating?

Absolutely. The thin profile and cement composition make it an excellent conductor of heat from underfloor systems.
