Why Polish Concrete?
Polishing concrete enhances its aesthetic appeal, increases durability, and makes it easier to clean. Unlike tiles or carpet, polished concrete does not trap dust or allergens, making it a healthier flooring choice. It also reflects light, helping to brighten indoor spaces. At Skyco Group, we deliver both residential and commercial polished concrete solutions tailored to Melbourne properties.
What You’ll Need
Polishing concrete requires specialised tools and materials. Here’s a basic list:
- Concrete grinder (available for hire at Kennards Hire)
- Diamond abrasives (various grits)
- Concrete densifier
- Polishing pads (resin-based with diamond grit)
- Concrete sealer from trusted brands like Dulux Australia or CSR
- Protective gear (gloves, goggles, and ear protection as per Safe Work Australia guidelines)
Step-by-Step Guide to Polishing Concrete
Step 1: Preparation
Thoroughly clean the surface to remove dirt, grease, or paint. For guidance, read our full guide on how to clean concrete in Melbourne. Preparation is critical to ensure the polish adheres correctly.
Step 2: Grinding
Attach a low-grit (30–40) diamond abrasive to your grinder. Move evenly across the surface to remove imperfections and level the slab. Gradually increase grit levels (80, 150, 400) as you progress. Think of it like sanding timber—starting coarse and moving finer until smooth.
Step 3: Densification
Apply a liquid concrete densifier to harden the surface. The densifier penetrates the pores and chemically reacts with free lime to create a denser, stronger slab. This step ensures long-lasting durability, especially for high-traffic Melbourne homes and businesses.
Step 4: Final Polishing
Switch to higher grit pads (800, 1500, 3000) for the final polish. Each pass increases smoothness and shine. Patience is key—this process transforms dull grey concrete into a glossy, mirror-like finish.
Step 5: Sealing
Finish by applying a high-quality sealer. Sealers protect against spills, stains, and scratches, while enhancing colour depth. Choose water-based sealers for eco-friendly projects or solvent-based options for maximum gloss. Products from Dulux and CSR are popular in Melbourne projects.
Polishing Techniques and Best Practices
Polishing concrete is part science, part craftsmanship. Move the grinder consistently across the surface to avoid streaks or uneven spots. Apply densifier evenly and allow full drying time. Use overlapping passes when polishing to achieve consistent shine. Always follow safety practices recommended by WorkSafe Victoria.
Maintenance of Polished Concrete
Once polished, maintenance is simple:
- Sweep or vacuum regularly to remove dirt and grit.
- Use a pH-neutral cleaner for mopping—avoid harsh chemicals.
- Re-buff with a high-grit pad if dull spots appear.
- Reseal every 2–3 years to protect against wear.
With proper care, polished concrete floors in Melbourne can last decades while retaining their shine.
