If there’s one suburb in Ballarat that’s kept us busy this past quarter, it’s Sebastopol. The combination of older homes with original concrete garages, owners doing genuine renovations rather than just cosmetic updates, and a real shift toward people using their garages as proper workspaces has meant the phone keeps ringing. We finished a job there two weekends ago that was a great example of how a Ballarat garage gets turned around — and a good reminder of why the cold-climate detail matters so much in our part of the world. Here’s how it came together, from first quote to final handover.
The Sebastopol brief
The clients had bought a 1970s brick veneer on a generous block in Sebastopol about eighteen months back. The garage was a freestanding double, original slab, untouched concrete, and they’d been using it as a combination of vehicle storage, woodworking shop, and overflow for the kids’ bikes and sports gear. The owner is a hobbyist woodworker who’d recently invested in a decent dust extractor and a proper bench, and he was tired of fighting the dust that rose off the porous concrete every time he turned a tool on. His partner wanted the space to look like something other than a building site when the roller door was up. Both of them wanted a floor that wouldn’t crack apart in winter when the slab moves.
The slab inspection
I always start with a proper assessment, and Sebastopol’s older slabs are no exception. We moisture-tested the concrete in three places — front, middle and back of the bay — and got readings in the moderate range, consistent with a slab that’s been sitting on Ballarat clay soil for fifty years without a vapour barrier underneath. There were two long hairline cracks running parallel to the front roller door track, a small chunk of edge spalling near the side door, and a deep oil stain in the right-hand parking spot from what looked like a couple of decades of slow-leaking sumps. None of this was unusual, but each issue had to be addressed before the new floor went down.
Why the prep is the whole job
I cannot say this enough to clients: the prep is the job. We diamond-ground the entire slab to a CSP3 profile to expose fresh concrete, chased and filled the cracks with flexible polyurea, ground out the spalled edge and rebuilt it with a structural epoxy patch, and used a citrus-based oil eliminator on the stained area before re-grinding it twice to remove any residual contamination. By the end of day one, the slab looked rough, dusty and unimpressive — and that’s exactly the point. A perfectly prepped slab is the only foundation that will hold an epoxy floor for fifteen-plus years through Ballarat winters. We covered the importance of this in detail in our piece on Ballarat garage floor preparation.
The cold-climate question
Anyone who’s lived through a Ballarat winter knows the temperature can swing by twenty-five degrees inside a single 24-hour cycle. That movement matters for an epoxy install — slab temperature has to stay within product spec for proper cure, and the cured floor has to handle ongoing thermal expansion and contraction. We scheduled this job for an autumn window where overnight temperatures were sitting in the high single digits but the slab itself was still holding warmth from the previous week of sun. We used a cold-tolerant epoxy primer that cures reliably down to about 5°C ambient, and we ran a dehumidifier in the closed garage overnight to keep humidity in the right band for the topcoat. Skipping these steps is the single most common reason cold-climate epoxy jobs fail. For more on why epoxy actually performs well in our climate when installed correctly, see our piece on epoxy flooring in Ballarat’s cold climate.
The flake choice
The clients had been agonising over flake colour for a fortnight before we started. We brought five physical samples to the second site visit and laid them on the slab in the actual garage lighting. They walked around them at three different times of day. The decision in the end came down to a mid-grey base with a black, white and silver-grey flake blend — which would mask sawdust, the inevitable woodworking spills, the occasional dropped tool, and still read as deliberate when the cars were in. Our piece on choosing colours and finishes for your Ballarat epoxy floor covers the way we walk clients through this decision in more detail.
The install itself
Day two was primer and base coat. The primer goes on first thing in the morning so it can soak into the freshly ground slab and chemically bond. Once it’s tacky (about two hours in our autumn conditions), we rolled the pigmented base coat. Two of us broadcast the flake by hand into the wet base — you stand at the wall and toss handfuls of flake straight up so it rains down evenly across about a metre of floor at a time, then move to the next position. Day three, we scraped and vacuumed the excess flake (about 30% of what gets broadcast comes back off), then rolled two coats of high-build polyaspartic topcoat. By the end of day four the floor was walkable, and the clients moved their cars back in on day five.
The handover and the woodworker’s reaction
I always enjoy the moment a client first sees the finished floor. The Sebastopol owner just stood at the open roller door for a good thirty seconds without saying anything, then walked the floor in his socks (which I quietly noted as approval). His partner was already pacing out where the new tool chest would go. We gave them a printed maintenance guide — pH-neutral cleaner, soft mop, no aggressive chlorine or acid cleaners, and a recommendation to put felt pads under the woodworking benches to protect the topcoat from drag marks.
What I’d say to other Sebastopol, Wendouree and Buninyong owners
If you’ve got a Ballarat garage that’s been sitting on dusty, stained, hairline-cracked concrete for the last few decades, the right time to deal with it is on a planned schedule, not after a section of slab finally fails. We work across all of Ballarat and the surrounding region, from Sebastopol and Wendouree to Buninyong, Mount Clear and out toward Delacombe. Every job is its own thing, but the principles stay the same: proper assessment, real prep, cold-climate-appropriate products, and a finish that you choose with the actual lighting and use of the space in mind. If your garage is on the list of “things to do this year,” we’d love to come and walk through it with you.
One last note on commercial work
While we do plenty of residential garages, we also do a lot of commercial epoxy across the Ballarat region — workshops, food prep spaces, showrooms, medical and veterinary clinics. The principles overlap with residential, but the products and the approach are different. If you’re looking at a commercial space, our piece on commercial epoxy flooring in Ballarat is a better starting point than this residential walk-through.
