The Ultimate Guide to Epoxy Flooring
If you're looking to sharpen your concrete floor, you know a thing or two about epoxy floor coatings. This coating combines an epoxy resin with a hardener to create a thermosetting polymer with exceptional strength and adhesion.
Epoxy is known for its toughness, making it a popular choice for garage floors and indoor concrete surfaces. It's resistant to tire marks, chemicals, stains, and general wear, making it an excellent choice. Another bonus is that you can use it to meet specific design requirements.
When it comes to epoxy flooring, durability and aesthetics go hand in hand—but only if the foundation is solid. Prepping the epoxy helps it bond to the concrete, which will prevent common issues like peeling, bubbling, and premature wear.
In this guide, we'll walk you through everything you need to know about epoxy flooring, with a special focus on why prep matters. By the way, if you're still on the fence about whether epoxy is right for you, take a look at our latest blog, Epoxy vs. Polyurea Floor Coatings.

What is Epoxy Flooring?
Epoxy flooring is a durable, high-performance surface coating that combines epoxy resin with a hardener. This chemical reaction forms a thermosetting polymer, resulting in a tough, long-lasting finish that bonds tightly to concrete surfaces.
Epoxy is known for its strength, adhesion, and resistance to chemicals. Because of this, it's a preferred choice for garages, basements, warehouses, and industrial spaces.
These floor coatings resist tire marks, stains, and abrasions, making them ideal for high-traffic areas. Thanks to their strong chemical bonds, correctly formulated epoxies provide long-lasting protection against spills, moisture, and daily wear.
Epoxy is an excellent choice for garages and other concrete surfaces in your home. Its strength and resistance to wear and tear also make it an excellent candidate for commercial properties, including:
Aircraft Hangars
Commercial Kitchens
Manufacturing Plants
Mechanical Equipment Rooms
Pharmaceutical Facilities
Restrooms
Warehouses
Epoxy flooring's performance ultimately depends on proper preparation and application—a key factor we'll explore in the next section.
2. The Importance of Surface Preparation
Here's the deal: epoxy won't properly adhere to an unprepared surface.
Skipping or rushing this important process can lead to problems and shorten the lifespan of your floor. This is why preparation is critical in achieving a long-lasting, professional-grade epoxy coating.
It's also why we recommend using a pro for this floor coating job. DIY epoxy kits are widely available, but proper floor preparation is complex and requires specialized tools and techniques. Hiring a professional ensures that every step is done correctly.
Why Surface Prep Matters
The success of an epoxy application depends not just on the quality of the product but on how well it bonds to the surface. A poorly prepped floor can cause:
Delamination (peeling) due to dirt, oil, or moisture interference
Bubbling caused by trapped air or moisture beneath the epoxy
An uneven or weak finish that wears down quickly under traffic and exposure
To meet industry standards, epoxy floors require a properly profiled surface that is free of contaminants, moisture, and structural damage.
Achieving this requires a step-by-step approach to cleaning, repairing, and preparing the concrete before application. Let's move on to the next section to learn more.
3. Steps to Properly Prepare Your Floor
Now that you understand why prep is crucial, let's walk through Epoxy Pro's key steps to get your concrete floor epoxy-ready.
1. Clean the Surface
Epoxy needs a spotless surface to bond effectively. Our team ensures they remove dirt, grease, oil, wax, and existing coatings. There are a few things we always consider when prepping the surface:
Use a degreaser, lacquer thinner, or acetone to remove stubborn stains.
Wipe down the surface with a clean paper towel before the solvent dries.
Clean before doing any sanding, as contaminants can be ground into the concrete.
2. Repair Cracks and Damage
A smooth, solid foundation is essential for epoxy adhesion. To avoid problems later, our team:
Fills cracks and holes with an epoxy patching compound or concrete filler
Removes any flaking, blistering, or chalking coatings before proceeding
Lets all repairs fully cure before moving to the next step.
3. Profile the Concrete
For epoxy to bond properly, the concrete must have a rough texture—this is called profiling. Here are some things we consider during this process:
Grinding is preferred for professional results, as it removes coatings and roughens the floor evenly.
Mechanical grinding or acid etching creates the proper surface profile.
Acid etching can be an alternative for DIYers but requires careful handling of chemicals.
To check if your floor is ready, sometimes we perform a water droplet test—if water beads up instead of absorbing, the surface needs further profiling.
4. Ensure a Dry and Dust-Free Surface
Moisture is one of the biggest culprits of epoxy failure. Our team checks for this by:
Testing for moisture using a plastic sheet or moisture meter.
If the surface is damp, we use heat lamps, fans, or dehumidifiers to dry it completely.
Then, we vacuum thoroughly to remove all dust and debris before applying epoxy.
These preparation steps create the foundation for a strong, durable, long-lasting epoxy floor.
Skipping or cutting corners in this process can lead to costly failures!
4. Choose the Right Epoxy and Application Techniques
Once we complete the epoxy prep process, it's time for our team to prepare for application.
Before applying epoxy, consider the type used, the application process, and curing times and conditions.
Types of Epoxy Coatings
There are three main types of epoxy coatings. Each one has distinct characteristics that can be used for different purposes.
Solvent-Based Epoxy: This style is recognized for its durability, high gloss, and resistance to petroleum contaminants. This solvent-based epoxy is a go-to option for garages, parking structures, and industrial facilities. It penetrates concrete well, creating a strong bond. However, due to high levels of volatile organic compounds (VOCs), its use has declined, with many regions enforcing strict regulations on its application. Proper ventilation is required when working with this type of epoxy.
Water-Based Epoxy: This low-VOC alternative is easier to apply, has little to no odor, and can sometimes be used on damp concrete. While it's more environmentally friendly, traditional water-based epoxies often fall short in chemical resistance and durability compared to other options. However, newer formulations have significantly improved performance, making them viable for residential and light commercial settings where a more frequent recoat is acceptable.
100% Solids Epoxy: This epoxy contains no solvents or water, meaning what is applied is what remains after curing, resulting in a thicker, more resilient coating. It offers the highest level of durability, with excellent resistance to chemicals, stains, and heavy impact. It is commonly used in industrial and commercial spaces where long-term performance is essential. However, it has a short pot life (30–40 minutes), requiring efficient application by experienced installers to avoid premature curing and application errors.
Application Techniques for a Flawless Finish
There are multiple steps to follow when applying epoxy floor coating. Each is crucial to ensuring proper adhesion and longevity.
Prime the Surface: Our team regularly uses a primer that helps seal the concrete and promotes better adhesion, preventing air bubbles or voids in the final coat.
Apply the Epoxy: Next, we use a squeegee and back-rolling technique to ensure even distribution and coverage. The number of coats will depend on the epoxy type and desired thickness.
Curing Considerations: Epoxy begins curing when the resin and hardener are mixed. Water- and solvent-based epoxies allow a longer working time (up to two hours), while 100% solids epoxy sets much faster. Temperature and humidity also impact curing times. Our team is knowledgeable in proper curing times.
Finishing Touches: A final topcoat can be added to enhance chemical resistance, depending on the project. A top coat can make the floor look better, and you can choose between smooth, satin, or textured finishes. We'll discuss options with you beforehand to make sure you're satisfied with our job.
5. Maintenance and Longevity
Once the epoxy floor coating is complete, proper curing time is critical. After this step, if done correctly, your epoxy floor should last for years—if it's properly maintained.
Factors like high heat, heavy vehicle traffic, and UV exposure can accelerate wear, but following simple care practices can keep your floor pristine for years.
Essential Epoxy Floor Care Tips
Regular Cleaning: Sweep or dust mop frequently to prevent dirt buildup. For deeper cleaning, use warm water and a mild, non-abrasive detergent—avoid harsh chemicals or soap-based cleaners that leave a residue.
Strategic Use of Mats and Rugs: Place mats at entrances to trap debris and use protective mats in high-traffic or heavy-use areas to prevent scratches and scuffs.
Prevent Chemical Damage: While epoxy resists most chemicals, clean spills promptly to avoid potential staining or surface degradation. If working with corrosive substances, use mats or trays to catch drips.
Use Proper Cleaning Tools: Opt for soft-bristle brooms, microfiber mops, and nylon brushes to avoid surface damage. If trying a new cleaner, test it on a small area of the floor first.
