With the help of a garage floor concrete coating, you can transform your garage into an entirely new and fully functional space. Not only will you improve its aesthetics, but you’ll also protect and extend the life of your concrete. How your garage floor coating is installed will affect its longevity and durability. This project is best suited for professionals unless you have access to the right tools and an understanding of the science behind concrete coatings.
You may have already noticed that your uncoated garage floor is staining, cracking, or wearing down in high-traffic areas. Unfortunately, these problems will only worsen over time. Left unaddressed, they could create safety hazards and decrease the usability of your space.
Your garage deserves better than that. Our team at Roe Paint has over 25 years of experience installing residential and commercial garage floor coatings that last. In this article, we will walk you through the process of how garage coatings are installed and what makes a great application. You’ll see the benefits of choosing a concrete coating to protect and preserve your garage floor. By the end of this guide, you’ll know exactly what goes into a high-quality installation and why it matters.
Step One: Essential Preparation for a Durable Garage Floor Coating
Preparing the surface is crucial before you even consider applying a coating. It’s like painting a wall—if you don’t prep it correctly, the paint will peel off quickly, and the same goes for your concrete floor.
The first part of the process is setting up the equipment, including bringing in the necessary tools like grinders and vacuums. The next step is thoroughly cleaning the concrete surface to remove any loose concrete, dirt, or grease. Particles and debris prevent the new coating from bonding properly. Once the surface is clean, the team starts the grinding process. This is the most important part of the preparation, as it scarifies (scratches) the concrete, creating the proper profile for the new coating to adhere to.
To complete this process correctly and efficiently, we use commercial-grade industrial grinders that weigh over 600 pounds. We also use a hand-held vacuum-assisted grinder to finish the floor edges. This edge work is essential, as the larger, propane-powered grinder can’t reach these areas. The goal is to create an even, textured surface that will allow the coating to bond properly.
A common problem with DIY garage floor coatings is that they do not include this grinding process. If the concrete is not properly prepared (ground), the coating cannot bond with it. Instead, it will sit on top of it and be more likely to crack and peel.
Step Two: Repairing Cracks in the Garage Floor
After grinding and before the coating can be applied, any cracks, pits, or damage in the concrete must be repaired. This isn’t just about how your garage looks—it’s about ensuring a long-lasting, durable finish.
Cracks or imperfections are filled with two component products. These materials are perfect for patching because they cure quickly and are ready to grind smooth within 30 minutes. By the end of this stage, the surface is clean, smooth, and ready for the next step.
Cracks and holes create weak spots that, if left untreated, can cause the coating to fail over time in those areas. That’s why filling these areas with repair materials is such an important step. Once the repairs are done and the surface is smoothed out, the floor is fully prepped and ready for coating. This ensures the coating will bond well and have the strength to handle everyday garage wear and tear.
Step Three: Applying the Polyaspartic Base Coat and Decorative Chips on the Garage Floor
Once the surface is prepared, it’s time to apply the base coat. Polyaspartic is the go-to choice for garage floors because it’s highly durable, flexible, and fast-curing. The polyaspartic base coat is mixed, poured directly onto the floor, and spread out with squeegees and rollers, creating a seamless, protective layer. While the base coat is wet, decorative chips are broadcast into the coating. These chips add both texture and a custom aesthetic to the floor.
The chips serve more than just a decorative purpose—they also improve the floor's traction, making it less slippery. This is a great safety feature if your garage is exposed to water or oil spills.
Step Four: Cleaning and Adding the Topcoat to Protect Your Garage Floor
Once the base coat has dried—typically within 1 to 2.5 hours—the next step is to scrape off any excess chips to ensure the floor is smooth and free from jagged edges. This ensures the decorative chips are evenly distributed, giving the floor a clean, professional finish.
After scraping, it’s time to apply the clear polyaspartic topcoat. This topcoat is mixed, poured onto the floor, and then back-rolled in a cross-hatch pattern to ensure even coverage. The topcoat gives your floor its glossy, durable finish and protects it from chemicals, stains, and the general wear and tear of daily garage use.
How Long Does a Garage Floor Coating Install Take?
You might think a garage coating job could leave your space unusable for several days, but that’s far from the truth!
Thanks to technological advancements and materials like polyaspartic, a garage concrete coating installation can often be completed in just one day. By the end of the process, you can walk on the floor within 4 to 5 hours and drive on it within 24 hours. Many homeowners are surprised at how quickly they can return to using their garage.
Simple Maintenance for Long-Term Durability of Your Garage Floor
Even though concrete coatings are built to last, proper maintenance will help extend the life of your garage floor and keep it looking fresh.
The beauty of a concrete coating is that it’s low maintenance. But to ensure your garage floor looks great for years, you’ll want to sweep up dirt and debris regularly. If you spill oil or chemicals, clean them up promptly to avoid stains. And avoid dragging heavy, sharp objects across the floor—while coatings are durable, they’re not immune to scratches.
With some care, your newly coated garage floor can last for decades, keeping your space looking polished and clean.
Can You DIY a Garage Floor Coating Project?
DIY kits may seem convenient, but they usually lack the durability and precision of a professional installation. Most homeowners don’t have access to the specialized grinding equipment necessary to provide the surface profile for the coating to adhere to. A lot goes into the intricate surface prep and the precise application of multiple layers. There are many small, but important details that must be handled correctly to ensure a long-lasting, durable finish—a professional garage floor coating installation guarantees a beautiful floor that will stand the test of time.
It’s tempting to head to the hardware store and grab a DIY concrete coating kit. You will absolutely save some cash, but it will likely cost you more in the long run (particularly when working with an entire garage floor). But, if you are working under a tight budget and only need to coat a small space, you could try your hand at garage floor coating after proper research.
Is a Garage Concrete Coating Worth It?
Absolutely. A professionally installed concrete coating can transform your garage floor into a durable, attractive surface that’s easy to maintain and built to last! You’ll increase your home’s value by investing in one of the most used (but underappreciated) spaces of your home.
Each step of the garage floor coating process—from preparation to the final topcoat—ensures your floor is ready to withstand daily wear and tear for years to come. The resulting garage floor is clean and pristine. So much so, that it may become your favorite room in the house.
