Transform old floors with durable concrete overlays in Perth. CoastCrete installs polished concrete overlays for Perth homes and businesses — a fraction of the cost of full slab replacement, finished in days.
Concrete overlays deliver the style and strength of a new polished concrete floor without removing your existing surface. A fraction of the cost of full concrete replacement, and far quicker to install.
A fraction of the cost of full concrete replacement. Skip the demolition + sub-base + reinforcement + 28-day cure. The overlay finish reads as a brand-new floor at lower material and labour cost.
Overlays can be applied and finished within days, minimising disruption to your home or business. There's no heavy demolition, waste, or dust — just a sleek new finish.
Choose from a wide range of colours, finishes, and textures to match your interior or exterior design. From natural concrete tones to decorative polished surfaces, the look is yours to spec.
Once cured, the overlay is polished and sealed to create a smooth, elegant, and durable finish that looks identical to a full-depth concrete slab.
A concrete overlay (sometimes called a polished concrete overlay or micro-topping) is a thin, high-strength cement-based coating applied over an existing surface. Once cured, it's polished and sealed to create a smooth, elegant, and hard-wearing finish that looks identical to a full-depth concrete slab. These overlays are typically just 3–10mm thick, making them the perfect option when height or budget constraints make new slabs impractical.
Our concrete overlays in Perth are ideal for both residential and commercial applications. Living rooms and kitchens — create a sleek, modern look. Bathrooms and laundries — smooth and moisture-resistant. Retail and hospitality venues — durable, professional finish. Outdoor areas and patios — slip-resistant surface options. Offices and showrooms — premium polished presentation.
Surface Preparation — we inspect, clean, and repair your existing surface to ensure strong adhesion. Overlay Application — a high-strength, polymer-modified cement mix is applied evenly across the floor. Polishing and Sealing — once cured, the surface is ground, polished, and sealed to your desired gloss level. Final Detailing — we apply a protective coating for long-term durability and stain resistance.
