Epoxy Garage & Shed Floors, Central Coast
You park on it, drop oil on it, walk sand and salt across it — and after a few decades of that, the average Central Coast garage floor is dusty, stained bare concrete. An epoxy coating changes that in a couple of days: a sealed, wipe-clean floor that handles cars, workbenches and wet swimmers traipsing in from the pool.
We arrange epoxy floors for garages, sheds and workshops Coast-wide, applied by appropriately licensed local coating contractors who prepare floors properly — which, on this coastline, is where most cheap epoxy jobs go wrong.

What an epoxy floor actually is
Epoxy is a two-pack resin that cures into a hard, chemical-resistant layer bonded to the concrete — far tougher than garage floor paint, which is why paint peels under hot tyres within a year or two and a properly installed epoxy system doesn’t.
A quality residential system typically looks like this:
- Diamond grinding of the whole slab to open the surface and remove laitance, old paint and contaminants. Acid etching alone is not enough on most older Coast slabs.
- Moisture assessment. Plenty of 1970s–90s garages on the Coast were poured without an effective vapour barrier, and humidity keeps ground moisture moving up through them. Where readings are high, a moisture-tolerant primer or vapour-barrier coat goes down first — skip it and the coating can blister off.
- Crack and spall repair with epoxy mortar, so defects don’t telegraph through the finish.
- Base coat in your chosen colour.
- Decorative flake broadcast (optional) — vinyl flakes scattered into the wet base coat for the speckled granite look most people picture. Flake also hides dust, tyre marks and minor slab imperfections far better than plain gloss colour.
- Clear topcoat, often polyurethane or polyaspartic rather than straight epoxy, because those chemistries resist the UV yellowing that hits epoxy near big north-facing door openings.
Anti-slip additive can be broadcast into the topcoat — sensible for garages that double as pool-towel drop zones, though as with any coating we describe grip as achievable, not guaranteed.
Who this service is for
- Home garages on 70s–90s brick homes from Woy Woy to Wyong, where the never-sealed original floor sheds dust onto everything stored in there.
- Sheds and workshops — the acreage and shed belt around Wyong, Ourimbah and Jilliby is steady work, because bare shed slabs are miserable to sweep and soak up every oil drip.
- Downsizers and renovators on the Peninsula turning the garage into a gym, hobby room or clean storage.
- Anyone selling — a coated garage floor is one of the cheaper presentation lifts a Coast property can get before photos are taken.
Epoxy suits interior, roofed concrete. For open outdoor slabs, look at driveway resurfacing instead; the concrete finishes guide sets the systems side by side.
Our process, start to finish
- Enquiry. Call (02) 0000 0000 or use the quote form. Tell us the suburb, roughly how many square metres (a single garage is usually about 18 m², a double around 36 m²), and what’s on the floor now — bare concrete, old paint, glue or previous coatings all change the prep.
- Inspection and moisture check. A licensed local contractor inspects the slab, checks for rising moisture, drummy patches and contaminants, and shows you flake blends and colour samples.
- Written quote. Itemised prep, system and colours. Everything on this page is guide pricing only; the quote after inspection is the real number.
- Clear-out and grind. You empty the garage (we’ll discuss options if that’s difficult), then the floor is diamond-ground with dust-extracted equipment, so grinding dust isn’t blown through your house or over the neighbour’s washing.
- Repairs and priming. Cracks and spalls filled, moisture-tolerant primer applied where readings call for it.
- Coating days. Base coat, flake broadcast if selected, then the clear topcoat. Coastal humidity affects cure windows, so contractors schedule coats around the weather rather than to a rigid clock.
- Handover. Plain-English cure times — typically light foot traffic within a day or so, vehicles after several days, product depending — plus care advice. Waste and grinding spoil leave with the contractor.
What affects the price
- Floor area — coating is priced largely per square metre, so a double garage doesn’t cost double a single once setup is spread across it.
- Slab condition — old paint, glue or badly oil-soaked concrete needs extra grinding and treatment.
- Moisture — slabs needing a vapour-barrier primer cost more than dry ones.
- System choice — plain solid colour sits at the lower end; full flake with a polyaspartic topcoat sits higher.
- Edges and extras — steps, plinths and coved skirting all add labour.
Indicative price guide
Indicative guide ranges only, based on typical Australian rates of roughly $35–$120 per square metre — every job is confirmed after inspection and a formal written quote.
| Project | Indicative range (guide only) |
|---|---|
| Single garage (~18 m²), solid colour | $900 – $1,800 |
| Single garage (~18 m²), full flake system | $1,400 – $2,500 |
| Double garage (~36 m²), full flake system | $2,300 – $4,300 |
| Large shed or workshop (50 m²+) | from ~$45/m², quoted per job |

What’s included — and what can add cost
Included as standard:
- Diamond grinding with dust extraction
- Standard crack and minor spall repair
- Primer, base coat and clear topcoat as quoted
- Flake broadcast where selected, with your choice from standard blends
- Removal of grinding spoil and coating waste from site
Itemised separately when needed:
- Vapour-barrier priming for high-moisture slabs
- Stripping thick paint, mastic or carpet glue
- Major repairs to broken or sunken slab sections
- Coved skirting, feature borders or two-tone zoning
- Anti-slip additive in the topcoat
Nothing gets added mid-job without being flagged first — surprises found under old coverings are priced before work continues.
Related services and where we work
If the slab is sound but you’d rather a natural concrete look than a coating, concrete grinding and sealing is the lighter-touch option. For the driveway outside the garage door, see driveway resurfacing. We arrange epoxy floors across the whole Coast — from shed country around Wyong to Peninsula renovators in Woy Woy and the family garages of Erina.
Epoxy garage floor FAQs
Will hot tyres pull the coating off?
Hot tyre pickup is a failure of cheap paint and poor prep, not of properly installed epoxy. Diamond grinding and a compatible topcoat are what prevent it — which is exactly why we don’t arrange etch-and-roll paint jobs.
My garage slab is from the 1980s. Is it too old for epoxy?
Age isn’t the issue; moisture and soundness are. Many older Coast slabs coat beautifully once ground, and if moisture readings are high the fix is usually a vapour-tolerant primer rather than a knock-back.
How long before I can park the car inside?
Typically several days after the final coat, with light foot traffic sooner. Exact times depend on the product and on humidity, so you get specific timings at handover rather than a one-size-fits-all figure.
Flake or solid colour — which should I pick?
Flake for most home garages: it hides dust, drips and blemishes and doesn’t show tyre marks the way gloss solid colours can. Solid colour suits workshops where you want to spot dropped fasteners instantly.
Why not just use a DIY epoxy kit?
DIY kits usually rely on acid etching and thin, water-based resins — on an old, contaminated or damp Coast slab that combination commonly peels within a couple of years. Mechanical grinding and commercial-grade resins are most of what you’re paying a professional for.
Is a licence required for this work?
NSW licensing requirements for residential building work depend on the value and type of job — check current thresholds with NSW Fair Trading. Either way, every job we arrange is completed by appropriately licensed local contracting partners, and you’re welcome to verify a licence before work starts.
