How Do You Remove Old Epoxy Flooring?
Professional removal is the right approach — not heat guns or chemical strippers from the hardware store. At Clear Cut Epoxy Flooring, we use four main methods depending on the floor:
- Diamond grinding — the standard method for most residential and light commercial floors; cuts back the coating and leaves a clean concrete surface ready for recoating
- Shot blasting — the go-to for large industrial and warehouse floors where grinding across open areas isn’t practical
- Scarifying — used on thick coatings, heavily lifted systems, or floors with multiple layers of old product built up over time
- Hand tooling — detail work around edges, columns, drains, and tight spots that larger machines can’t reach
The right method comes down to floor size, how thick the coating is, and what condition the concrete is in underneath. A proper site assessment tells us which approach — or combination of approaches — is right for your floor.
Why Peeling and Delaminating Epoxy Can’t Simply Be Recoated Over
It’s tempting to think a fresh coat on top will sort it out. It won’t.
When epoxy starts peeling or lifting, the bond between the coating and the concrete is already gone. A new coat on top doesn’t fix that — it just sits over a surface that’s already failing. Within months, sometimes weeks, it starts doing the same thing.
There’s also what’s hiding underneath. Oil, moisture, and concrete dust trapped beneath a failing floor don’t go away when you recoat. They work against the new product from day one.
The only real fix is stripping it back to bare concrete, finding out what went wrong, and dealing with it before anything new goes down.
The real risk of recoating over a failed system A new coat over a delaminating floor bonds to a surface that’s already letting go — not to the concrete. You end up paying twice.
Removal Methods Used for Hobart Floors
The right removal method depends on the type of floor, the condition of the coating, and how much area needs to be covered. Here’s what we use:
Diamond Grinding: The most common method for residential garages, home workshops, and light commercial spaces around Hobart. Grinding cuts the old coating back and leaves a clean, profiled concrete surface without damaging the slab underneath.
Shot Blasting: Better suited to large open floors — warehouses, industrial sheds, and factory spaces where grinding the entire area by hand would take far too long. Shot blasting covers ground quickly and leaves a consistent surface profile across the whole floor.
Scarifying: Used when the coating is thick, heavily built up, or has multiple old layers sitting on top of each other. Scarifying cuts deeper than grinding and handles situations where the standard approach won’t get the job done.
Hand Tooling: For the areas machines can’t reach — edges, drains, around columns, and tight corners. Hand tooling finishes off what the larger equipment starts, making sure no old coating is left behind in spots that matter.
Why Epoxy Floors Fail: What Removal Reveals
Removal isn’t just mechanical — it’s diagnostic. Stripping back the old coating shows exactly what went wrong the first time. Here’s what we commonly find:
Substrate Assessment: What We Look for After Removal
This is the step that separates a specialist from someone who just strips and recoats. Once the old coating is gone, we assess the slab before anything new goes down.
Slab Condition and Crack Assessment: We check the concrete for cracks, spalling, and any soft or weak spots that removal has exposed. Cracks that were hidden under the old coating need to be repaired and stabilised — otherwise they telegraph straight through a new install and the same problems come back.
Moisture and Vapour Testing: With the coating removed, we test the slab for moisture vapour transmission. In Hobart especially, where damp conditions are common through winter, this step matters. The results tell us whether the concrete needs additional treatment before a new system goes down.
Surface Profile and Contamination Check: We confirm the surface profile left by the removal process is suitable for the next product, and check for any remaining contamination — oil, adhesive residue, or laitance — that could affect how the new coating bonds. If something needs addressing, we deal with it at this stage.
Hobart Properties We Service for Epoxy Removal
We work across a wide range of properties in and around Hobart. Residential garages and home workshops make up a big part of what we do — floors that have been coated once, sometimes twice, and are now lifting or past the point of recoating. We also work through commercial workshops, trade premises, and light industrial sheds where a failing floor has become a safety concern or a compliance issue.
Hospitality premises are another area we cover regularly. Cafés, kitchens, and food preparation spaces need floors that meet health and safety standards — and that starts with proper removal and substrate preparation before any new product goes down.
We service properties across Glenorchy, Moonah, Clarence, Rosny Park, Rokeby, and Brighton, as well as the broader Hobart area. If you’re not sure whether we cover your location, just get in touch and we’ll confirm.
What Comes Next After Old Epoxy Is Removed
Once the old coating is gone and the slab has been assessed, you’ve got a clean slate to work with. What happens next depends on what the substrate assessment shows and what the space needs going forward.
For most Hobart properties, a new epoxy system is the logical next step — whether that’s a standard garage floor coating, a commercial-grade system for a workshop, or a food-safe product for a hospitality premises. In some cases a decorative concrete overlay makes more sense, or the customer decides to go with a different flooring product altogether.
We don’t push any particular direction. Once removal is done and the slab is assessed, we give you a straight read on the condition of the concrete and what it’s ready to take. The decision on what goes down next is yours to make with the right information in front of you.
Why Choose Clear Cut Epoxy Flooring for Removal Work in Hobart?
Most flooring contractors will strip a floor if you ask them to. What sets us apart is what happens before, during, and after the removal.
- Local Hobart knowledge — we work in Hobart conditions every day and know what damp slabs, cool winters, and older concrete do to coatings over time
- Correct method selection — we assess the floor first and choose the removal approach that suits the coating type, floor size, and substrate condition
- Substrate assessment included — removal and assessment go together; we don’t strip and walk away without knowing what the slab needs next
- Failure diagnosis — we identify what caused the original coating to fail so the same mistake isn’t repeated on the next install
Frequently Asked Questions
If the coating is peeling, lifting, or bubbling in multiple areas, it needs to come off. A recoat only works when the existing coating is still firmly bonded to the concrete across the whole floor. We can assess this on site and give you a straight answer.
It depends on the size of the floor and the condition of the coating. A standard residential garage typically takes a day. Larger commercial or industrial floors take longer. We give you a realistic timeframe before we start.
Not when it’s done correctly. Our equipment is set up to remove the coating without cutting into the slab. In some cases removal actually exposes damage that was already there — cracks or weak spots hidden under the old coating.
Yes. We work in garages, workshops, and commercial premises that are in use. We’ll talk through access requirements and any staging options before the job starts to minimise disruption.
The most common causes are poor surface preparation before the original install, moisture coming up through the slab, oil contamination in the concrete, or a product that wasn’t suited to the environment. Removal usually makes the cause clear.
Yes. We remove standard epoxy, thick build-up systems, multi-layer coatings, and failed decorative finishes. The removal method we use depends on what’s on the floor and what condition it’s in.
Not always. After removal we assess the slab for moisture, contamination, and surface condition. If everything checks out, recoating can follow quickly. If there are issues that need addressing first, we’ll tell you what they are and what needs to happen before a new product goes down.
