What Is Concrete Floor Grinding? A Beginner’s Guide for Homeowners and Business Owners / by Scott Gaylor

If you're asking what is concrete floor grinding—you're not alone. Whether you're prepping your floor for epoxy, polishing your garage, or upgrading your commercial facility, concrete floor grinding Richmond Hill is where it all begins. It's the first step to achieving a smooth, strong, and long-lasting surface—done right, it changes everything.

Wondering how the pros do it? Let's walk you through the essentials.

What Exactly Is Concrete Floor Grinding?

Concrete floor grinding is a mechanical surface prep method that uses industrial machines with diamond-embedded discs to remove surface imperfections. The process smooths out irregularities, exposes fresh concrete, and ensures proper adhesion for coatings like epoxy or urethane.

There are two types of grinding:

●  Light Grinding: Best for minor surface prep, cleaning off adhesives, or opening pores for sealants.

●  Aggressive Grinding: Removes heavy coatings, evens out cracks, and creates a raw, highly textured surface for full epoxy systems.

Fun fact: According to ConcreteNetwork, over 80 percent of epoxy flooring failures occur due to improper surface prep—grinding prevents that.

Why Is It Crucial Before Epoxy Flooring?

If you're investing in epoxy, floor prep is non-negotiable. Grinding is the foundation that ensures the epoxy bonds deep into the surface, preventing peeling, bubbling, or cracking.

Here’s what grinding accomplishes:

● Removes dirt, oils, and contaminants

● Levels uneven surfaces

● Opens concrete pores for better absorption

● Creates a clean, textured base for coatings

Question to consider: Have you ever applied a floor coating and watched it peel within months?

That likely happened due to skipping this vital first step.

Tools and Techniques Used in Grinding

Professional-grade grinders come in various sizes, from handheld to large walk-behind machines. Each is fitted with diamond segments of different grit levels, usually ranging from:

●  6 to 20 grit for aggressive grinding

●  30 to 80 grit for general surface prep

●  100+ grit for polishing finishes

For commercial and industrial jobs, planetary grinders offer better control, while vacuum systems keep the space dust-free.
