Garage floor coatings are one of the fastest-growing home improvement requests across Port Stephens — particularly in the newer estate areas of Medowie, Raymond Terrace and Salamander Bay where double garages are standard. The appeal is straightforward: a raw concrete garage floor is dusty, hard to clean, shows every oil stain, and looks industrial in a house that’s otherwise well-finished. A quality floor coating transforms it in a single day.
We install epoxy and polyaspartic floor coatings across Port Stephens. For coastal locations — which is most of Port Stephens — we strongly recommend polyaspartic over standard epoxy. Here’s why.
Epoxy vs Polyaspartic: The Coastal Difference
Both epoxy and polyaspartic are excellent garage floor coatings. Both are hardwearing, chemical resistant and easy to clean. But for Port Stephens’s coastal environment, there’s a meaningful difference.
UV stability — Standard epoxy turns yellow under UV exposure. In a garage with a window, a skylight, or even a door that’s regularly open, UV enters and the epoxy will eventually amber and discolour. In a coastal location where UV intensity is high year-round, this yellowing is more pronounced and happens faster. Polyaspartic is inherently UV-stable — it doesn’t yellow, even under continuous UV exposure.
Cure time — Polyaspartic cures dramatically faster than epoxy. A polyaspartic floor is done in one day: application in the morning, walk-on by afternoon, vehicle-ready within 24 hours. Standard epoxy requires a two-day process and longer before vehicle traffic is recommended.
Temperature flexibility — Polyaspartic can be applied in a broader temperature range than epoxy. This matters in Port Stephens’s coastal conditions where workshop-style garages can get warm in summer and cool in winter.
Performance at equivalent cost — The price difference between polyaspartic and standard epoxy has narrowed significantly. For coastal Port Stephens homes, polyaspartic is our default recommendation.

Garage Floor Coating Systems We Offer
Solid Colour Polyaspartic
A single-colour, high-gloss or satin finish. Clean, professional look. Available in a wide range of colours — from light greys and whites through to mid-tones. The most popular choice for residential garages.
Decorative Flake (Chip) System
Coloured vinyl flake is broadcast into the base coat before it cures, creating a speckled, textured finish. The flake provides additional slip resistance and effectively hides any minor surface imperfections. Very popular in residential garages — the speckled finish looks clean and hides dirt between cleans. Available in a range of colour blends.
Metallic Epoxy
A high-visual-impact finish that creates a fluid, marbled appearance using metallic pigments. More expensive and more specialised than standard systems — suited to showcase garages, home gyms or workshop spaces where the floor is a feature rather than a background.
The Installation Process
Garage floor coatings live or die by surface preparation. A beautifully applied coating on unprepared concrete will fail within a year or two. Preparation is where the time goes, and it’s what you’re paying for when you choose a professional over a hardware-store DIY kit.
Step 1: Surface preparation The concrete floor is diamond-ground to open the pores and remove any contamination. Oil spots are treated with specialist degreaser and, if necessary, an oil-specific primer. Any cracks or divots are filled. The floor is vacuumed and blown clean.
Step 2: Primer coat A penetrating primer is applied that chemically bonds to the concrete. This is the foundation of the system — nothing should sit between the concrete and the primer.
Step 3: Base coat The main coating layer. For polyaspartic, this goes on after the primer. Flake is broadcast at this stage for decorative systems.
Step 4: Top coat / sealer The final protective coat — hardwearing, chemical-resistant, UV-stable. This is the surface you’ll be walking and driving on.
Timing: A polyaspartic floor is typically done in 4–6 hours of application time. Add preparation and you’re looking at a full day’s work. Walk-on in 3–4 hours of completion, vehicle-ready in 24 hours.
Coastal Considerations for Garage Floors
Most Port Stephens garages are attached to residential homes and don’t have direct salt air exposure. But in beachfront and harbour-front properties — particularly in Shoal Bay, Corlette, Nelson Bay and Fingal Bay — garages can have significant salt air ingress, particularly if the roller door is frequently open in an onshore breeze.
For coastal-exposed garages, we apply the UV-stable and salt-resistant formulations rather than standard interior-grade products. The application process and visual result is identical, but the coating’s resistance to the coastal environment is significantly better.
Cost Guide for Garage Floor Coatings
| Garage Size | Approximate Area | Price Range |
|---|---|---|
| Single garage | 20–30m² | $2,400–$4,000 |
| Double garage | 35–55m² | $3,500–$6,500 |
| Triple garage | 60m²+ | $5,500–$9,000+ |
What affects price:
- Size of the floor area
- Condition of the concrete — oil-contaminated floors need more prep work
- System chosen — solid colour vs decorative flake vs metallic
- Any crack repair needed
Common Garage Floor Situations in Port Stephens
Raw concrete that’s never been coated — The ideal starting point. Clean, uncontaminated concrete prepares easily and produces the best coating results. Raw concrete garages are common in newer Medowie and Raymond Terrace estate homes.
Oil-stained concrete from years of vehicle use — Very common across Port Stephens, particularly in older properties. Oil must be treated before any coating will bond. Multiple degreasing passes and an oil-specific primer are required. Severely contaminated concrete may need diamond grinding through the contaminated layer.
Failed previous DIY coating — We see this regularly. Homeowners apply a hardware-store epoxy paint, it looks good for six months, then starts peeling. The old coating needs to come off entirely before a professional-grade system is applied. This adds prep time but the result will last decades rather than months.
Garage with workshop use — Heavy vehicle use, chemicals, and tool impacts require a harder-wearing system. We recommend a thicker application and can discuss specific requirements.
Frequently Asked Questions
Can I put cars back in the garage the same day as the coating? With polyaspartic, typically 24 hours is sufficient. We confirm the specific timing based on conditions — temperature and humidity affect cure rate. Don’t try to rush it — the additional hardness that comes with full cure makes a meaningful difference to how the floor performs under tyre movement.
My garage floor has oil spots from 20 years of parking. Can it still be coated? Yes, but it needs proper treatment. Oil contamination is the most common cause of garage floor coating failure. We use a specific degreaser protocol and oil-tolerant primer that allows the system to bond correctly over contaminated concrete. Severe oil damage may require grinding back to clean material.
Will the floor be slippery? Solid colour polyaspartic in a satin finish has natural non-slip character. Decorative flake systems are even better — the flake creates texture and grip. In a wet garage during rain or car wash, any smooth coating can feel slippery — anti-slip aggregate can be added to the top coat if grip is a priority for you.
Is epoxy or polyaspartic better for a Port Stephens garage? For coastal Port Stephens, polyaspartic. It won’t yellow under UV (important if your garage gets any natural light), it cures faster, and performance is equivalent or better at a similar price point. For a completely enclosed dark garage, standard epoxy is an acceptable option.
How long does a garage floor coating last? Quality polyaspartic systems last 15–25 years with appropriate care. The main causes of premature failure are inadequate surface preparation (which we don’t cut corners on) and DIY products that aren’t rated for vehicle traffic.
Can you do the garage floor and driveway in the same week? Yes — and we can often schedule them in adjacent days to minimise disruption. Contact us with details of both surfaces.
