Sealed concrete floors are popular in industrial and commercial spaces. They are durable, cheap, and low-maintenance. But, like any flooring solution, sealed concrete isn’t perfect for every situation. A poor flooring choice in a commercial or industrial warehouse, food prep facility, or big store can be a big disappointment.
At CustomCrete, we know how important it is for your flooring to meet the demands of your business. We have over 20 years of experience with delivering high-quality, durable flooring solutions for all kinds of businesses. We’ve seen the common and not so common issues with sealed concrete, and we know how to prevent them. Here are five key issues to be aware of, along with solutions that can keep your floors looking and performing their best.
Sealed Concrete can have a Slippery Surface
Why It Happens
Sealed concrete can get slick under some conditions. This is especially true when exposed to water, oils, or certain chemicals. The smooth, sealed finish that sealers provide often comes with reduced traction, which can create a safety issue in areas where spills or wet conditions are common. Commercial kitchens, warehouses, and outdoor walkways are especially prone to this. Even a small amount of moisture can make the surface dangerously slippery.
How to Avoid It
To improve traction and make your floor safer, consider adding an anti-slip additive to the sealer. These additives are mixed into the top coat. They create a slight texture on the floor. This improves grip without hurting the concrete’s look. Some anti-slip options even enhance the aesthetic with a subtle matte finish. If spills or moisture are frequent in your space, speak with your installer about anti-slip solutions to avoid a slippery surface that could lead to accidents or liability issues.
Sealed Concrete is Prone to Scratches and Scuffs
Why It Happens
Sealed concrete is tough, but not scratch-proof. It can get scuffed in high-traffic areas or where heavy equipment is used. Foot traffic, forklifts, and dragging pallets can wear down the sealer. This leaves marks that detract from the floor’s polished look. Over time, these scratches can accumulate, making the surface look uneven and worn out.
How to Avoid It
Using a high-quality, abrasion-resistant sealer is essential in areas where floors see a lot of heavy use. These sealers add protection against scratches. They help keep the polished look for longer. Also, routine maintenance can keep your sealed concrete at its best. Apply a sacrificial wax topcoat to take the brunt of scratches. Planning for periodic upkeep, especially in high-traffic areas, will protect the surface and make a noticeable difference in its longevity and appearance.
The Look of the Concrete Affects the Look of Your Sealed Floors
Why It Happens
The condition of your concrete before sealing plays a significant role in the final appearance of your floors. If the concrete is uneven, cracked, or stained, these imperfections may still be visible through the sealer. While a sealer can enhance the appearance and protect the surface, it cannot mask pre-existing flaws. The sealer’s transparent quality means that any cracks, discoloration, or rough patches will still show through, impacting the overall look.
How to Avoid It
To achieve a polished, professional look, proper surface preparation is essential before applying a sealer. This includes repairing cracks, filling in any holes, and smoothing uneven areas. Grinding or polishing the surface can help create a clean, uniform foundation for the sealer to adhere to. This extra step ensures that the sealed concrete achieves the best possible finish, and it helps the coating last longer by bonding to a smooth, prepared surface. If aesthetics are a priority, surface preparation should never be overlooked.
Susceptibility to Staining
Why It Happens
Although sealed concrete is durable, it’s not entirely impervious to staining. Because some types of sealers are porous, liquids like oil, grease, or certain chemicals can seep into the surface over time, causing discoloration. In commercial settings like garages, kitchens, or manufacturing spaces, frequent exposure to staining agents increases the likelihood of stains, which can detract from the floor’s clean appearance.
How to Avoid It
To prevent stains, consider using a high-quality, non-porous sealer, or adding a stain-resistant topcoat for extra protection. Regular cleaning can also help remove spills before they penetrate the surface. For areas prone to spills, establish a quick cleanup protocol to prevent staining. In high-stain environments, a non-porous sealer or sacrificial topcoat acts as a barrier, keeping the floor cleaner and protecting it from deep-set stains that are harder to remove.
Sealed Concrete Can Have Wear and Tear in High-Traffic Areas
Why It Happens
Sealed concrete in high-traffic areas can wear down more quickly, especially under constant foot or vehicle movement. Heavy forklift traffic can cause wear, leading to a patchy look. It also exposes the concrete to damage as the protective layer wears.
How to Avoid It
For high-traffic areas, consider using a heavy-duty sealer, such as an epoxy sealer, which is designed to handle constant use. Routine maintenance, including reapplication as needed, can keep these areas looking even and durable. Regular upkeep for high-traffic areas helps prevent damage and maintain a consistent finish. It saves time and money in the long run.
Making the Right Choice for Your Concrete Floors
Sealed concrete can provide a durable, attractive surface for your floors. But, it’s vital to know the potential challenges to get the best results before you get started. By addressing these issues before they arise, you can ensure your concrete floors last longer and perform better. Small choices can have a big impact down the line. For example, adding anti-slip additives or picking a sealer that is ideal for temperature changes.
