What Is a
Concrete Overlay?

Transform tired or uneven floors into seamless, high-performance surfaces with our concrete overlay systems. Designed for both refurbishment and new builds, these cement-based concrete overlays deliver the full look and strength of polished concrete — with greater control over colour consistency, finish level and speed of installation.

Leading materials formulated for smooth, durable and beautifully refined finishes. Whether you're creating a full aggregate exposure, a salt-and-pepper aesthetic, or a creamy polished finish, these overlays provide a consistent, architectural result across every project.

Perfect for commercial, retail, education, and residential spaces, our concrete overlay flooring combines performance and design freedom — offering a modern, low-maintenance and sustainable alternative to traditional floor coverings across the UK.

The Installation Process

01
Survey & Specification
We visit site to assess the existing substrate — checking for moisture, adhesion, levelness and contamination. We then specify the correct overlay system for your project.
02
Substrate Preparation
The existing floor is diamond-ground or shot-blasted to achieve the correct surface profile. Any cracks, voids or loose areas are repaired. A bonding primer is applied.
03
Overlay Application
The overlay material is mixed and applied in layers using trowels, squeegees or self-levelling spreaders. Build-up continues until the specified thickness is achieved.
04
Grinding & Flatting
Once cured, the surface is diamond-ground through a sequence of grits to achieve the specified flatness, aggregate exposure level and surface clarity.
05
Sealing & Finishing
A penetrating densifier is applied, followed by topcoat sealers to lock in the finish and provide stain, moisture and abrasion resistance. Final sheen matched to sample.
06
Handover & Aftercare
Full walkthrough with the client, aftercare and maintenance guide provided. The floor is ready for light use within 24 hours, full use within 72 hours.

FAQs

Yes, in most cases. Tiles must be firmly bonded to the substrate with no hollow areas, cracking or movement. We test adhesion using a hammer tap test and check moisture levels before confirming suitability. If a small number of tiles are loose, we can fix those prior to application. Heavily textured tiles may require additional fill coats.

Yes — concrete overlay systems are highly compatible with underfloor heating. The thin profile (3–10mm) actually performs better than tile for heat transfer. The UFH system must be commissioned and pressure-tested before we start. We run our own temperature and moisture checks as part of the pre-installation survey.

Most domestic projects (up to 60m²) take 3–5 days on site from preparation through to final seal. Self-levelling overlays that require polishing add a day or two. Larger commercial projects are programme-specific — we'll confirm the timeline in your written quotation.

Microcement is a specific type of thin concrete overlay (2–3mm) made from polymer-modified cement, applied in fine layers and sealed with a topcoat. It's particularly popular for walls, stairs and surfaces that need a very fine detail. Thicker overlay systems allow for polishing, aggregate exposure and a more traditional polished concrete aesthetic. We'll advise on the right product for your project at the survey stage.

Cracking in an overlay is almost always caused by movement in the substrate beneath it. This is why thorough substrate assessment is critical — we won't apply an overlay over a substrate that shows signs of active movement or structural instability. If the underlying slab or screed has movement joints, we reflect those through the overlay system. Hairline shrinkage cracks are a natural characteristic of cementitious systems and do not indicate failure.
