Why Prep Grinds Matter More Than You Think

When it comes to polished concrete, everyone loves to admire the sleek, glossy finish. But here’s the secret no one talks about: the magic doesn’t start with polishing. It starts with prep grinding. Without a proper grind, your concrete floor is like a house built on quicksand—doomed from the start.

At NZ Grinders, we’ve seen it all in Hamilton—from floors covered in stubborn adhesives to concrete that looks like it survived an earthquake. That’s why we emphasize prep grinding. It’s the foundation of any successful concrete finish, and trust us, skipping this step is not an option.

What Exactly Is a Prep Grind?

A prep grind is the process of removing coatings, glue, or imperfections from a concrete surface before applying a finish like polished concrete, epoxy, or an overlay like vinyl tiles or engineered flooring. Think of it as exfoliation but for floors. We use industrial grinders fitted with diamond tooling to create a smooth, clean surface that ensures whatever comes next will adhere properly and last longer.

What Happens If You Skip a Prep Grind?

• Your new flooring may delaminate or peel off faster than you can say “should’ve called NZ Grinders.”
• The surface might remain uneven or rough, making the final finish look unprofessional.
• Adhesion issues can cause cracks, bubbles, or lifting in coatings like epoxy or sealants.
• Any dirt, glue, or contaminants left behind will compromise durability.

In short, cutting corners on prep grinding is a recipe for disaster. And we’re not in the business of disasters—we’re in the business of making Hamilton’s floors look and perform their best.

Why Hamilton Businesses Rely on Prep Grinds

Hamilton is home to a variety of commercial and industrial spaces, from retail stores and cafés to warehouses and offices. Each of these spaces has different flooring needs, but they all have one thing in common: a strong foundation is key.

For example, we recently tackled a project in a Hamilton warehouse where an old epoxy coating was failing. The floor was uneven, cracking, and peeling in places. After a thorough prep grind, we gave it a fresh polished concrete finish. The result? A stronger, smoother, and more durable floor that’s now built to last.

How NZ Grinders Gets Prep Grinds Right

At NZ Grinders, we don’t just grind and hope for the best—we take a strategic approach. Here’s what makes our process stand out:

1. Surface Assessment

Before we fire up our grinders, we evaluate the condition of your concrete. We look for existing coatings, damage, or contaminants that could impact the final finish.

2. The Right Equipment for the Job

We use top-of-the-line Husqvarna and HTC grinders equipped with the perfect diamond tooling for your surface. Whether your concrete needs a light touch-up or aggressive removal, we have the gear to get it done efficiently.

3. Dust-Free Grinding

Concrete grinding can get messy, but we use industrial vacuums to keep dust to a minimum. That means less cleanup and a safer environment for everyone involved.

4. Customized Solutions

Not all concrete is created equal. Some floors need deep grinding, while others require just a surface scratch. We tailor our approach based on your floor’s needs and your desired outcome.
