Turning Tired Concrete into a Work of Art
You’ve got a concrete slab sitting under layers of paint, glue, or carpet. It’s dull, forgotten, and—let’s be honest—ugly. But what if we told you that old concrete can shine again? That those cracks and stains can vanish, leaving behind a floor so beautiful it could star in a showroom?
At NZ Grinders, we specialize in turning “meh” into “magnificent.” We transform existing concrete floors into polished masterpieces that not only look incredible but perform flawlessly for decades.
Why Refurbishing Beats Replacing
You might think ripping out flooring and starting fresh is the logical choice—but polishing what’s already there is smarter, faster, and often cheaper. Here’s why:
- Lower costs per square metre than full replacement.
- Less waste, since we’re enhancing the concrete you already have.
- Minimal downtime, keeping your home or business running smoothly.
- Structural integrity stays intact—no new slab required.
Refurbishing old concrete is one of the most cost-effective ways to upgrade your space without the mess and stress of starting over.
The Step-by-Step Transformation
1. Assessment & Preparation
First, we inspect the slab for cracks, coatings, and surface hardness. Damaged areas are repaired or levelled to create a perfect base.
2. Grinding & Honing
Next, we grind the surface using progressive diamond pads—this removes imperfections and reveals the natural beauty of the concrete beneath. You can choose the level of stone exposure – mostly with existing floors this will be full stone.
3. Polishing & Densifying
We apply a densifier that strengthens the surface and then polish it to the sheen you choose, from matte to mirror gloss.
4. Sealing & Finishing
Finally, we seal the floor to lock in shine and durability. The result? A hard-wearing surface that’s easy to clean and designed to impress.
