Epoxy Garage Floor Guide — Prep, Grind, Coat (Gold Coast and Brisbane)
Why Epoxy Garage Floors Are Popular in SEQ
Gold Coast and Brisbane climate makes garages one of the most used spaces in Australian homes. A quality epoxy floor transforms a bare concrete slab into a durable, easy-clean surface.
New estates in Coomera, Pimpama, Upper Coomera, and Pacific Pines have hundreds of homeowners applying epoxy garage floors every month.
The Number One Reason Epoxy Fails
Inadequate surface preparation.
Epoxy applied to unprepared concrete bonds to the weak surface laitance, not the concrete itself. Professional concrete grinding creates the surface profile needed for proper adhesion.
Step-by-Step Preparation
1. Clear and clean the garage
Remove everything. Sweep thoroughly. Look for oil stains — treat with degreaser before grinding.
2. Check moisture levels
Use a moisture meter. If above 75% RH, use a moisture-tolerant epoxy primer.
3. First grind pass
Use 30-50 grit disc. Work in overlapping rows removing surface laitance and contamination.
4. Second grind pass
Switch to 50-80 grit. Make a second pass at 90 degrees to the first.
5. Edge work
Use a hand-held angle grinder for edges 150-200mm from walls.
6. Clean thoroughly
Vacuum all dust. Wipe with clean dry cloth.
7. Final moisture check
Wait 24 hours, retest moisture. Apply primer when dry.
