Why Skipping This Step Can Cost You in the Long Run
When it comes to concrete coatings, the end result is only as good as the surface it’s applied to. Whether you’re installing epoxy in your garage or upgrading a commercial floor with a polyaspartic system, professional surface preparation is the most important step in achieving a durable, long-lasting finish.
At Select Flooring Systems, we’ve seen the difference that quality prep makes firsthand. If you’re planning a project in Dayton or the surrounding Miami Valley area, here’s why surface prep shouldn’t be skipped or rushed, and what goes into getting it right.
Why Surface Prep Matters
Proper surface preparation ensures that the coating bonds directly to the concrete slab. If the floor isn’t prepped correctly, even the highest-quality coating can delaminate, bubble, or peel prematurely.
Top reasons to prioritize professional prep:
- Maximizes adhesion for long-term performance
- Removes contaminants that interfere with bonding
- Helps identify and repair surface damage
- Creates a clean, consistent profile for even coating application
If you’ve ever seen a peeling or flaking garage floor, the root cause is usually poor prep, not poor product.

Step-by-Step: What Professional Surface Prep Involves
Here’s a closer look at what our team includes in the concrete surface prep process before applying any floor coating system:
1. Mechanical Grinding or Shot Blasting
We use commercial-grade grinders or shot-blasting machines to profile the concrete surface. This removes any existing coatings, sealers, or adhesives while giving the new system something to grip. This is critical for long-term adhesion.
2. Thorough Cleaning
After grinding, we vacuum the floor using industrial HEPA equipment to remove all dust and debris. Even small particles left behind can weaken the bond and cause failure.
3. Moisture Testing
Concrete is naturally porous, and hidden moisture can cause bubbling or peeling under a coating. We perform moisture testing to confirm that the slab meets manufacturer guidelines. If excess vapor is present, we may recommend using a moisture mitigation barrier.
4. Crack and Joint Repair
Cracks, pits, and damaged areas are repaired using specialized fillers. This prevents those imperfections from telegraphing through the final coating and ensures a smooth, even surface.
5. Edge Work and Detail Areas
Our team carefully grinds and prepares corners, transitions, and tight areas using handheld tools. These areas are often overlooked in DIY installs but are essential for a uniform finish.
DIY vs. Professional Surface Prep
While DIY kits are tempting, most skip critical prep steps. Many rely on acid etching or light sanding, which often fails to properly open the concrete surface.
Professional surface prep includes:
- Correct surface profiling for adhesion
- Moisture evaluation
- Structural assessment and repair
- Use of commercial-grade tools
Cutting corners during prep can lead to expensive repairs or premature failure. To see how coatings can perform when properly installed, explore how epoxy holds up in high-traffic areas.
Long-Term Benefits of Proper Prep
Investing in surface prep pays off with a coating system that looks better, lasts longer, and requires less maintenance.
Benefits include:
- Superior adhesion and fewer failures
- Uniform texture and gloss
- Greater resistance to wear, impact, and moisture
- Improved safety and aesthetics
Whether you’re coating a residential garage or upgrading a commercial showroom, a well-prepared surface is key to getting results that last.
