Your kitchen floor has thirty seconds to stop a slip before someone hits the deck hard. A commercial kitchen in Melbourne runs at full pace, and the floor takes a beating that a garage floor will never see. We've installed hundreds of epoxy surfaces across the city, and the difference between a garage floor that lasts and a commercial kitchen floor that actually protects your staff comes down to three things: surface preparation, slip resistance, and food-safe chemistry. Most flooring crews cut corners on prep because nobody sees it. We do the opposite.
Why Commercial Kitchen Floors Demand Different Treatment
A garage floor gets parked on. A commercial kitchen floor gets cooked on, spilled on, hosed down, and walked across by people carrying hot pans and wet feet. The stakes are higher. Your liability exposure is higher. Your staff safety is not negotiable.
We've worked in kitchens across Brighton, Toorak, South Yarra, and the inner suburbs where restaurants take their reputation seriously. The difference between a floor that holds up for five years and one that fails in eighteen months is rarely about the epoxy resin itself. It's about what's underneath. A garage floor lives indoors, stays relatively dry, and doesn't face constant thermal shock. Commercial kitchen floors endure temperature swings from the walk-in fridge to the hot line. They face acids from citrus and vinegar, fats that make surfaces slippery, and moisture that never stops.
The surface underneath has to be bulletproof. That's why we use diamond grinding, not acid etching.
Why Diamond Grinding Wins Over Acid Etching
Acid etching is fast and cheap. It's also the wrong choice for a commercial kitchen. Here's what happens. Acid etching eats away at the top layer of concrete and leaves a porous surface. That sounds good for adhesion, but in a kitchen, that porosity becomes a trap for bacteria, food particles, and moisture. You're creating the conditions for failure.
Diamond grinding removes the degraded surface layer mechanically. We cut into the concrete with precision, creating a texture that bonds the epoxy but doesn't trap contaminants. The floor stays cleaner. The epoxy bonds stronger. The surface lasts longer.
Our crew does the grinding in-house. We don't subcontract it to someone else. That means we control every variable. We know exactly how much material we've removed, how clean the floor is, and what the surface profile looks like. We measure it. Most crews guess.
For a kitchen in the Mornington Peninsula or Bayside suburbs, that difference matters more than you'd think. The salt air affects concrete differently. The seasonal humidity swing is wider. A properly ground floor handles those conditions because the epoxy bond is right from the start.
Food Safety Standards and Slip Resistance Ratings
Food-safe epoxy doesn't mean the resin is edible. It means the surface meets Australian food safety standards for materials that contact commercial food preparation areas. We specify systems that comply with AS 3744 standards and can handle regular sanitising with chlorine-based cleaners without breaking down. That matters because your kitchen doesn't stop being sanitised just because you laid a new floor.
Slip resistance is measured in Australia using the Ramp Test, which produces a Rating of Slip Resistance (RASR). Commercial kitchens need a minimum RASR of 36 on wet surfaces. Most standard epoxy coatings sit at 25 to 30. That's not enough. We use broadcast flake and textured systems that push 40 to 45 RASR. The flakes create a texture that breaks the surface tension of spilled liquids and gives footwear grip even when wet.
Here's the thing most installers don't tell you: slip resistance degrades over time. A floor that starts at 45 RASR will drop to 38 or 40 after two years of foot traffic and cleaning. The finish wears smooth. We factor that into our specification. We build in margin. A floor we install will still meet food safety requirements after three years of hard use.
Why Preparation Wins the Game
We spend three to four times longer on surface preparation than most crews do. For a commercial kitchen, we grind to a profile of 1.5 to 2.0 mil. We blow off all dust with air compressors. We check moisture with a calcium carbide test. We don't spray epoxy until we're certain the concrete can accept it. If there's rising damp, we treat it. If there are cracks, we seal them. If there's old adhesive or paint, we grind it out.
That prep work costs more. It takes more time. It gets billed to the job. Most owners wince at the line item. Then they get a floor that doesn't fail after two years, and suddenly it makes sense.
A seven-year warranty on a commercial kitchen floor means we're willing to stand behind the outcome. We don't offer that warranty on sloppy work. That warranty is built on good preparation and the right system for the task.
