What Is Epoxy Flooring?
Epoxy flooring is a seamless, high-performance floor coating system. Epoxy flooring consists of a two-part epoxy resin and hardener mixture when combined, they create a strong, durable, and chemical-resistant surface.
The study “Reducing Electric Static Charge Generated from Epoxy Flooring Materials” by AlOtaiby, A., et al. (2014) explores the effects of adding metallic particles like iron, brass, and copper to epoxy composites to reduce static charge in flooring tiles. Epoxy without fillers produced the highest negative voltage when sliding against rubber, but adding metallic particles, especially brass and copper, considerably minimized this charge.
The voltage generated increased with load, and higher conductivity in the metallic particles lowered the amount needed to reach zero voltage. In terms of safety, the friction coefficient of the composites exceeded the recommended standard of 0.5 for slip resistance, with values above 1.0 for all specimens. Specifically, the friction coefficient reached 1.4 when brass content was high enough to diminish the generated voltage, confirming these composites as safe for flooring applications.
A friction coefficient of 0.5 means that the surface offers 50% resistance to sliding, the recommended standard for safe walking conditions. In this case, if the surface provides 50% resistance, it’s considered safe enough to prevent slipping during normal walking.
The study found that all the tested epoxy flooring composites had friction coefficients greater than 1.0, meaning they provided over 100% resistance to sliding. For instance, when brass particles were added, the friction coefficient reached 1.4, which translates to 140% resistance to sliding. This means the flooring is exceptionally slip-resistant, making it very safe for walking, even in challenging conditions. The addition of copper particles also expanded friction substantially, further magnifying safety. The study recommends using brass and copper-filled epoxy for flooring due to their balance of low static charge and high slip resistance.
What Are the Types of Epoxy Flooring?
The types of epoxy flooring include self-leveling epoxy, epoxy mortar flooring, epoxy flake flooring, graveled epoxy flooring, and anti-static epoxy (ESD). The most common types of epoxy flooring are explained below as noticed by the National Association of Floor Covering Technicians (2020):

How to Install Epoxy Flooring?
To install epoxy flooring, you prepare, priming, mixing epoxy, application, and curing. The application necessitates spreading the mixture evenly, and the curing process. The following explains the process of installing epoxy flooring as indicated by the Flooring Contractors Association (2024):
- Surface Preparation
- Clean the surface: The floor must be clean, dry, and free of oil, grease, or dust.
- Repairs: Any cracks or imperfections in the concrete need to be repaired before applying the epoxy.
- Priming
- Primers are applied to create better adhesion between the epoxy and the concrete surface. Some primers also act as a moisture barrier.
- Mixing Epoxy
- The resin and hardener are mixed in the correct ratio to form the epoxy. The mixture needs to be applied within a specific time frame before it begins to harden.
- Application
- The epoxy is disseminated evenly across the surface using a roller or squeegee. Multiple layers are required depending on the desired thickness. The application requires spreading the mixture evenly, and the curing process, which lasts 24-72 hours, solidifies the floor, ensuring durability and longevity.
- Curing
- The epoxy needs time to cure and harden. This takes 24-72 hours depending on the product and environmental conditions.
Professional installation ensures optimal results for epoxy flooring projects. According to a study by the National Association of Floor Covering Technicians, professionally installed epoxy floors have a 10-20 years or longer success rate in terms of longevity and performance.
What Are the Benefits of Epoxy Flooring?
The benefits of epoxy flooring are durability, aesthetic appeal, chemical and stain resistance, low maintenance, and slip resistance. The most common benefits of epoxy flooring are listed below as given by the Floor Contractors Association (2024):

- Slip Resistance: Epoxy flooring is customized with textured finishes or additional coatings like epoxy flakes to amplify slip resistance. This increases safety, particularly in environments prone to moisture or oil, such as commercial kitchens or factory floors. AlOtaiby, A., et al. (2014) explicate that a friction coefficient of 0.5 indicates the surface provides 50% resistance to sliding, which is the recommended standard for ensuring safe walking conditions.
How to Maintain Epoxy Flooring?
To maintain epoxy flooring, regular cleaning, avoiding abrasive cleaners, spot cleaning, and re-coating. The most com
- Regular Cleaning: Daily sweeping or vacuuming is essential to prevent dirt and debris from scratching the epoxy surface. Mopping with a mild detergent and water maintains the floor’s clean, shiny appearance without causing damage.
- Avoid Abrasive Cleaners: Harsh or acidic cleaning products erode the epoxy coating as time passes. To preserve the floor’s smooth finish, use non-abrasive cleaners that won’t dull or degrade the surface.
- Spot Cleaning: Spills are to be cleaned immediately with a soft cloth and mild cleaner, especially in industrial settings where chemicals potentially damage the epoxy. Quick action precludes staining and material breakdown.
- Re-Coating: Persistently, especially in high-traffic areas, the epoxy floor begins to wear down. Applying a new layer of epoxy restores its appearance and durability, extending the floor’s lifespan massively.
What Are the Safety Considerations for Epoxy Flooring?
The safety considerations for epoxy flooring encompass ventilation during installation, slipperiness, chemical safety, and proper footwear. The most important safety considerations for epoxy flooring are elaborated below as discussed by Khamaj, et al. (2019) in the study “ENHANCING THE SAFETY OF EPOXY FLOORING MATERIALS IN WET WORKING CONDITION”:
- Ventilation During Installation: Epoxy contains fumes that are harmful if inhaled in large amounts. Ensure the area is well-ventilated during installation, and consider using protective masks.
- Slipperiness: While epoxy flooring is slip-resistant, it becomes slippery when wet or oily. Adding textured finishes or slip-resistant coatings mitigates this risk, particularly in commercial kitchens or wet environments. In the study by Khamaj, et al. (2019), the safety of epoxy flooring materials in wet working conditions was enhanced by addressing two key concerns: static electricity generation and slip resistance.
The authors proposed using iron machining chip waste as a filler material for epoxy flooring to increase the friction coefficient and reduce electrostatic charges generated when shoes make contact with the floor.
Experimental results indicated a major cutback in static charge, especially in wet sliding conditions, as water helped dissipate static electricity. Friction was improved with 1% to 2% iron powder, depending on shoe hardness, while 4% iron powder was found to be optimal for lessening the electrostatic charge. These findings suggest that iron-filled epoxy is functional in managing the risks of slippage and static charge in industrial settings.
- Chemical Safety: In industrial settings where chemicals are used frequently, ensure that the epoxy flooring is compatible with the substances handled. Some chemicals erode certain types of epoxy.
- Proper Footwear: In areas where slip-resistant finishes are not applied, it is advisable to wear footwear with adequate grip to reduce the risk of falls.
How long does epoxy flooring last?
Epoxy flooring lasts 10-20 years when properly installed and maintained. The Concrete Network provides that residential coatings have a duration of 30 years, depending on foot traffic, while in industrial environments, they last 2-3 years.
Is epoxy flooring slippery when wet?
Yes, epoxy flooring is slippery when wet. Adding anti-slip additives during installation increases traction to prevent injury from slipping. The National Floor Safety Institute (NFSI) estimates that in the United States, floors and flooring materials contribute to 2 million injuries annually, with 22% of slip-and-fall incidents leading to over a month of missed work. The study “Reducing Electric Static Charge Generated from Epoxy Flooring Materials” by AlOtaiby, A., et al. (2014) found that all tested epoxy flooring composites had friction coefficients exceeding 1.0, showcasing they provided more than 100% resistance to sliding. The study advises brass and copper-filled epoxy for flooring, as these materials provide an optimal balance of low static charge and high slip resistance.
