Flawless garage floor coatings start with something you don’t see: the preparation of the concrete below it. Skipping or cutting corners in this step is one of the most common reasons coatings fail over time. If the surface isn’t prepped properly, even the strongest coating can lift, peel, or crack in high-traffic areas.
What Is a Concrete Surface Profile?
For a coating to grip the concrete, the surface must have texture. This texture is measured by the Concrete Surface Profile (CSP), a rating system developed by the International Concrete Repair Institute. Smooth floors have a CSP of 1, while extremely rough ones rate as high as 10.
For residential garages, the best results come when the floor is prepared to a CSP of about 3 or 4. This is just rough enough for the concrete coating system to bond but not so rough that it affects the finish.
The Best Way to Prepare Concrete
Different methods can change the texture of a floor, but not all of them provide the right result. Acid etching or water jetting don’t create enough grip for a garage floor coating, while heavy-duty options like sandblasting go too far.
Professional grinding equipment, however, hits the sweet spot. Contractors in Toledo use grinders to achieve the right CSP, and propane-powered grinders make the process faster and more consistent than electric alternatives. These machines can cover larger areas quickly and don’t have the limitations of cords or electrical outlets, making them ideal for both garages and larger spaces.
Why Hire a Pro?
Proper preparation requires the right tools and knowledge. DIY kits or shortcuts can’t replicate the results of professional-grade equipment. Choosing an experienced contractor means you get both—the right surface profile and a garage floor coating that holds up year after year.
Final Word
Before installing your garage floor coating, always ask about the preparation process. In Toledo, we take this step seriously, because it’s what ensures your floor looks sharp and performs well long after installation day.
