Concrete Overlay for Factory Floor Restoration: The Complete Guide

Q: Do we need to shut down production for this?

No, work is planned around your operating schedule, without the extended shutdown a full slab replacement would require.

Q: Is Screed Plus suitable for very uneven floors?

Screed Plus is positioned within Floorzy's EverShield range as the surface-repair system for levelling and repairing uneven factory floors.

Q: How thick is the overlay, and will it change floor levels significantly?

EverShield overlay systems are typically applied in the 2 to 5mm range, thin enough to avoid major clearance issues in most facilities.

Q: Does it help with the dust problem specifically, or just cracks and levelling?

Both. EverShield overlay systems are designed to permanently seal the concrete surface, addressing dusting alongside levelling and crack repair.

Every factory floor eventually gets to this point: dusting under every forklift pass, spiderweb cracks running across walkways, low spots where water pools after washdown, and a surface that just looks tired no matter how often it’s swept. The instinctive next step feels like it has to be a full floor replacement — break it out, repour, wait weeks for it to cure. In most cases, that’s not actually necessary. A concrete overlay can restore the surface without any of that, and this guide walks through exactly how.

Is It Time to Restore Your Factory Floor?

Before deciding between repair and replacement, it helps to be honest about what’s actually happening on the floor. These are the signs that a factory floor has moved from “needs cleaning” to “needs restoring”:

✓Visible dusting — a fine grey powder that reappears no matter how often the floor is swept or mopped

✓Surface cracks, especially spreading or connecting across high-traffic lanes

✓Uneven or low areas where water, oil, or cleaning fluid pools instead of draining

✓Pitting, spalling, or chipped patches from years of forklift and machinery traffic

✓A porous, absorbent surface that stains easily and is difficult to keep visibly clean

✓Previous patch repairs that have already failed or started lifting

If two or more of these sound familiar, the floor has likely reached the point where routine maintenance won’t fix it — but that still doesn’t necessarily mean the slab itself needs to be broken out and replaced.

What Is a Concrete Overlay, and Why Does It Work?

A concrete overlay is a thin, high-strength layer — typically in the 2–5mm range for industrial systems — applied directly on top of an existing concrete slab. Rather than demolishing the damaged surface and starting from the sub-base up, an overlay bonds to the existing slab, fills and levels out the damage, and creates a new wearing surface on top of it.

This works because, in the overwhelming majority of factory floor problems, the structural slab underneath is still sound — it’s the top few millimetres of surface that have failed: cracked, dusted, pitted, or worn uneven. Replacing the entire slab to fix a surface-level problem is expensive and slow. An overlay system fixes the actual layer that failed, bonded permanently to the structure that’s still doing its job.

The mistake we see most often: facilities assume a cracked, dusting floor automatically means the slab has structurally failed and needs full replacement. In most cases the base slab is fine — it’s the wearing surface that’s gone, and that’s a very different, much less disruptive repair.

Introducing Screed Plus — EverShield® by Floorzy

Screed Plus is Floorzy’s surface-repair overlay system, part of the EverShield® family — Floorzy’s line of overlay systems built to permanently seal, strengthen, and transform dusty, cracked concrete floors without demolition. Within that family, Screed Plus is specifically positioned as the surface-repair option: designed to level and repair uneven factory floors, and it’s Floorzy’s most economical system for this type of restoration.

What Screed Plus is built to fix

Uneven factory floors — levels out low spots, dips, and inconsistent surfaces that affect forklift movement and drainage.
Surface cracking — bridges and repairs cracked areas as part of the overlay application, rather than leaving them to spread further.
Dusting concrete — permanently seals the porous, dust-generating surface that untreated or worn concrete produces under traffic.
Worn or damaged wearing layers — restores a durable, even surface without touching the structural slab underneath.

How the Restoration Process Works

Assessment

Floorzy reviews the floor’s condition, damage extent, and site access to confirm the overlay is the right fit before any work starts.

Surface Preparation

The existing slab is cleaned and mechanically prepared so the overlay bonds properly across the full area.

Overlay Application

Screed Plus is applied across the floor, levelling low areas and repairing cracked or damaged sections as it goes.

Cure & Handover

The overlay cures on-site, and the floor is handed back with a restored, level, dust-sealed surface — with work planned around your production schedule throughout.

Because the entire process happens on top of the existing slab rather than inside it, there’s no need to break up the floor, remove debris by the truckload, or wait through the extended cure times that a full-depth concrete pour requires.

Overlay vs. Full Replacement vs. DIY Patching

Factor	DIY / Spot Patching	Full Slab Replacement	Concrete Overlay (Screed Plus)
Addresses the root cause	No — patches fail again at the edges	Yes, but often unnecessary if the slab is sound	Yes — restores the full wearing surface
Downtime	Low, but repeated over time	High — demolition, pour, extended cure time	Minimal — planned around your schedule
Demolition required	No	Yes	No
Dust control	Untreated areas keep dusting	Yes, if finished correctly	Yes — dust-sealed surface
Cost	Low upfront, but recurring	Highest — full materials, labor, and disposal	Floorzy’s most economical system
Result consistency	Visible patchwork, uneven finish	Uniform, but a major undertaking	Uniform, level, permanently sealed surface

The clearest way to read this: DIY patching treats the symptom and fails again at the same spots. Full replacement solves the problem but at a cost and disruption that’s rarely justified when the slab itself is still structurally sound. An overlay is the option that actually matches the size of the real problem for most factory floors.

Why This Matters Beyond Appearance

Worker health and air quality. A dust-sealed floor keeps fine concrete dust out of the air your team breathes, which matters for both comfort and long-term respiratory health.
Machinery protection. Airborne concrete dust accelerates wear on machinery, sensitive equipment, and moving parts — sealing the source reduces that wear across the whole facility.
Safety. A level, even surface reduces trip hazards and makes forklift and pallet-truck movement more predictable and safer.
Operational continuity. Because the work happens without demolition, production doesn’t need to stop for the length of the project.

Field Example

Restoring a Dusting, Uneven Warehouse Floor

A common scenario for this kind of restoration: a warehouse floor that’s been in constant use for years, with visible dusting under forklift traffic, low spots where washdown water pools, and a scattering of surface cracks that keep spreading despite repeated spot patching. Full replacement would mean shutting down a section of the warehouse for weeks — a cost most facilities can’t absorb during an active operating schedule.

Applying an overlay system like Screed Plus follows the same process outlined above: assessing the floor, preparing the existing slab, applying the overlay to level and repair the surface, and allowing it to cure — all planned around the facility’s working hours rather than shutting the site down. The result is a dust-sealed, level floor restored without touching the structural slab underneath, and without the extended downtime a full pour would require.

This reflects a typical use case for concrete overlay restoration rather than a specific verified project. Actual scope, timeline, and outcome depend on the floor’s condition, size, and site access — a site assessment is the only reliable way to confirm suitability and cost for your own floor.

Frequently Asked Questions

Will a concrete overlay work if my floor already has cracks?

In most cases, yes. Overlay systems like Screed Plus are designed to bridge and repair surface cracking as part of the application, provided the underlying slab is still structurally sound. A site assessment confirms suitability for your specific floor.

How is this different from just patching the damaged spots?

Spot patching only treats the specific damaged area and often fails again at the edges where old and new material meet. An overlay restores the entire wearing surface as one continuous layer, which is far less likely to fail at isolated points.

Do we need to shut down production for this?

No, that’s the point of an overlay system — work is planned around your operating schedule, without the extended shutdown a full slab replacement would require.

Is Screed Plus suitable for very uneven floors?

Screed Plus is specifically positioned within Floorzy’s EverShield® range as the surface-repair system for levelling and repairing uneven factory floors, making it well suited to this exact problem.

How thick is the overlay, and will it change floor levels significantly?

EverShield® overlay systems are typically applied in the 2–5mm range, thin enough to avoid major clearance issues with doorways, equipment, or thresholds in most facilities, though this should be confirmed for your specific site during assessment.

Does it help with the dust problem specifically, or just cracks and levelling?

Both. EverShield® overlay systems are designed to permanently seal the concrete surface, addressing dusting alongside levelling and crack repair, rather than treating dust as a separate problem.
