Epoxy is sold on appearance and bought for durability, but whether it lasts has almost nothing to do with the coating and almost everything to do with slab preparation. In Hamilton there are two extra hurdles: older garage slabs poured without a vapour barrier can push moisture up and lift the coating, and an unheated garage only spends part of the year warm enough to cure a coating properly. Ask about grinding and about slab temperature.
What drives your price
Surface preparation method
Diamond grinding or shot blasting the slab to open the concrete costs more than acid etching and is what actually makes the coating bond, so this line is the clearest signal of whether a quote is for a lasting floor or a cosmetic one.
Coating system
A single-coat DIY-grade epoxy, a full broadcast flake system with a clear topcoat, and a polyaspartic build are separate products with separate lifespans, and the harder systems resist hot tire pickup and chemicals far better.
Slab repair before coating
Cracks, spalled patches, pitted areas, and old oil contamination all have to be repaired or degreased first, and a slab with years of staining and freeze damage can carry more repair cost than coating cost.
Flake, colour, and topcoat options
Full flake broadcast uses more material than a light scatter, and an anti-slip additive or an extra clear coat both add material and a return visit, which is time as well as product.
What this means in Hamilton
Road salt is the load this floor actually carries
Hamilton winters put a lot of salt on the roads, and it arrives in the garage packed into wheel wells and dripping off the underside of the car all season. That brine sitting on bare concrete is what causes the pitting and surface scaling seen on so many local garage slabs, and it is the single best argument for coating a floor that is still in good condition rather than waiting until it is not.
Slab moisture from clay soil underneath
Garage slabs in older Hamilton properties were frequently poured directly on grade with no vapour barrier below, and with dense clay holding water under them they can transmit moisture upward for years without ever looking wet. Moisture arriving from beneath a coating is a leading cause of blistering and peeling, which is why a moisture test before quoting is a good sign in a contractor rather than a stalling tactic.
A seasonal application window in an unheated garage
Epoxy and polyaspartic products cure within a manufacturer-specified temperature range measured at the slab, not in the air, and an unheated Hamilton garage slab stays cold well into spring and gets cold early in fall. That effectively limits the good application window to the warmer months unless the installer heats the space, so booking in late autumn often means paying for temporary heat or waiting.

Common questions
When is the best time of year to epoxy a garage floor in Hamilton?
Late spring through early fall, because the products cure to a slab temperature rather than an air temperature and an unheated garage slab lags the outdoor temperature by weeks. Off-season work is possible but usually means paying to heat the space.
Is acid etching good enough instead of grinding?
Grinding or shot blasting gives a far more reliable bond, and most coating failures trace back to preparation rather than product. If a quote is notably cheap, check whether it includes mechanical preparation or just an etch and rinse.
Will epoxy stop my garage floor from pitting further?
A properly bonded coating keeps salt brine and water off the concrete, which is what causes the pitting in the first place. It will not repair existing damage on its own, so pitted areas need patching before the coating goes on.
How long before I can park on it?
Walking on it usually comes well before driving on it, and hot tires are the real test. Follow the specific product's cure schedule rather than a general rule, because parking too early is what causes tire marks lifting the finish.
