Sydney hardware stores sell epoxy kits for $200–$500. Professional epoxy installation costs more upfront. Here's the honest breakdown of what you actually get — and why most DIY epoxy fails within 2–3 years.
| Factor | DIY Epoxy Kit | Surface Master Professional |
|---|---|---|
| Surface preparation | Acid etch (unreliable) | Diamond planetary grinding to CSP 2–4 |
| Coating thickness | 2–3 mils total | 12–18 mils multi-layer system |
| Moisture testing | Rarely done | Moisture meter test before priming |
| Pot life management | User-controlled, often rushed | Controlled by trained operators |
| Topcoat | Usually included, thin | Polyaspartic or polyurethane clear |
| Lifespan | 1–5 years typical | 10–20 years with correct prep |
| Warranty | Product only | Full installation warranty |
| Total cost | Appears cheaper — often re-done | Upfront cost, no redo |
The most common reason is inadequate surface preparation. DIY kits typically use acid etching, which creates only a CSP 1 profile — insufficient for epoxy adhesion. Without diamond grinding to CSP 2–4, the epoxy has no mechanical bonding surface and delaminates within 1–5 years.
About concrete grindingNo. Acid etching creates a shallow surface profile (CSP 1) that is insufficient for epoxy flooring systems. Diamond grinding creates a CSP 2–4 profile with consistent mechanical bonding sites. All professional epoxy contractors use grinding as standard preparation.
About our grinding serviceYour floor is ready when: it has been diamond ground to CSP 2–4 profile; moisture content is within acceptable limits; all existing coatings have been removed; and any cracks or spalls have been repaired and cured. A professional contractor will confirm all of these at a site inspection.
Book a site inspectionEpoxy peeling is almost always caused by: insufficient surface preparation — not grinding to the correct CSP profile; moisture trapped in the slab; or incorrect primer. Hot tyre lift is prevented by using a polyaspartic or polyurethane topcoat.
Epoxy flooring cost guideDIY epoxy can work for very low-traffic utility areas where dust control is the goal rather than a durable coating. For any floor that will see regular vehicles, machinery, or heavy foot traffic, professional installation delivers better value over the life of the floor.
Our epoxy systemsRemoving failed DIY epoxy typically costs $20–$40/sqm for removal alone, then full preparation and coating on top. A redo project usually costs 2–3x what the original professional quote would have been.
