Proper preparation is the single most important factor in a successful epoxy floor installation. The contractors in our Sydney network consistently emphasise that preparation accounts for roughly 70% of the total project time — and it is what separates a floor that lasts 15+ years from one that peels within months.
Moisture Testing
Sydney's coastal humidity and occasional groundwater issues mean moisture testing is essential before any epoxy application. Professional contractors use calcium chloride or relative humidity tests to ensure the slab is suitable.
Diamond Grinding
The most effective preparation method is diamond grinding, which profiles the concrete surface to create a mechanical bond for the epoxy. The contractors we connect you with use commercial-grade grinders that deliver consistent results.
Crack and Joint Repair
Existing cracks, spalling and control joints need to be addressed before coating. Professional contractors fill cracks with epoxy filler and can install joint sealants to prevent future cracking.
What You Can Do Before the Contractor Arrives
Clear the garage of all items, remove any existing paint or sealer (or let the contractor handle this), and ensure good ventilation. The contractors in our network will handle the rest.
