1. Check Traffic Type and Volume
Understanding the type and volume of traffic your facility handles is essential for choosing the right floor coating system. Traffic patterns directly influence the required coating thickness, material selection, and overall durability. This evaluation lays the groundwork for determining the best coating specifications for your needs.
For areas with light foot traffic, wear and tear are minimal. However, high-use zones, like workstations or entryways, endure concentrated stress and demand thicker coatings or reinforced systems to prevent early wear.
When it comes to forklift traffic, the challenges are unique. Heavy loads, sharp turns, and steel wheels create intense point loads that can crack or chip standard coatings. Forklifts also expose floors to chemical spills and heat, adding to the stress on the coating.
Rolling loads – such as carts and dollies – cause constant abrasion. Unlike static loads, the repeated friction from rolling equipment gradually wears down coatings. Narrow wheels, in particular, focus pressure onto smaller areas, leading to faster degradation.
Facilities handling mixed traffic types, such as foot traffic, forklifts, and machinery, need coatings designed to withstand these varied stresses.
Load calculations are critical for determining the minimum thickness of a coating. Equipment legs, pallet jacks, and storage racks can create concentrated stress points that thinner coatings cannot handle. Facilities storing heavy materials or using overhead cranes require coatings tough enough to handle both regular loads and the impact of dropped items.
For high-traffic areas, fast-curing polyurea systems are a practical solution. These coatings allow foot traffic within hours and can support full loads in just 24 hours, minimizing downtime during installation.
Movement patterns within your facility also play a role in coating selection. For instance, straight-line traffic between loading docks and storage areas causes linear wear, while intersections and workstation approaches face multidirectional stress. Flexible polyurea systems are particularly effective in these situations, thanks to their ability to handle impact and directional changes.
Temperature swings caused by traffic can also affect coating performance. Refrigerated facilities, where forklifts move between cold storage and ambient areas, experience thermal cycling that can crack rigid coatings. Flexible polyurea systems are better suited for these environments due to their ability to withstand temperature fluctuations.
It’s wise to plan for future traffic changes as well. If your facility is likely to undergo equipment upgrades, capacity increases, or operational shifts, investing in a more durable coating upfront can save you from costly recoating down the line.
To guide your coating choices, map out high-wear areas, note equipment weights, wheel types, and operating conditions. This thorough traffic assessment not only helps in selecting materials but also shapes your long-term maintenance strategy. A well-informed plan ensures that your coatings stand the test of time.
2. Test Durability and Resistance
When selecting industrial coatings, it’s essential to assess their durability and resistance to ensure they meet your specific operational needs. These tests provide insights into how different coatings perform under real-world industrial conditions, helping you make the best choice for long-term performance.
Abrasion resistance is a key factor, particularly for industrial floors that endure constant wear from equipment, foot traffic, and sliding materials. Machinery like forklifts, pallet jacks, and dragged tools create friction that can wear down surfaces. Polyurea coatings are often a top choice here, as they can resist abrasion effectively while maintaining flexibility to avoid cracking.
Impact resistance evaluates a coating’s ability to handle sudden forces without cracking, chipping, or peeling. This is tested using methods like the falling weight and Gardner impact tests, which follow international standards such as ISO 6272-1. These tests ensure that the coating can withstand the rigors of industrial use.
Coating hardness also plays a critical role in durability. Harder coatings are better at resisting scratches and gouges, but there’s a trade-off – over time, they may become brittle. The Shore hardness scale is commonly used to measure this property, with industrial coatings typically ranging from Shore A 80 to Shore D 65.
Polyurea coatings stand out for their fast curing times and ability to handle thermal cycling, making them ideal for environments with frequent temperature changes, such as food processing plants or cold storage facilities.
Epoxy systems, on the other hand, offer strong chemical resistance and excellent adhesion. However, they can become brittle in colder environments or under repeated impacts. Polyurethane coatings strike a middle ground, combining decent impact resistance with UV stability, which makes them suitable for areas exposed to natural light.
Temperature resistance is another critical consideration. Many industrial facilities experience significant temperature fluctuations, and coatings that can expand and contract without cracking will help minimize maintenance costs over time.
When evaluating test results, think about the unique stress factors in your facility. A coating that excels in a lab setting might not perform as well under your specific conditions, such as exposure to chemicals, temperature variations, or mechanical stress. Always request test data that closely matches your operational environment to make the most informed decision about the coating’s durability and longevity.
3. Review Chemical and Environmental Exposure
When choosing the right industrial floor coating, it’s essential to consider both the chemicals and environmental conditions your facility faces. This step complements durability testing by focusing on external challenges that could impact the coating’s performance and lifespan. Each environment presents its own set of hurdles, requiring coatings designed to address those specific needs.
Chemical exposure is a key factor to evaluate. Start by identifying the substances your floors come into contact with. Industrial settings often expose surfaces to acids like sulfuric or hydrochloric acid, hydrocarbons such as gasoline and diesel, and caustics like sodium or potassium hydroxide. Other common contaminants include oil, gas, and road salt.
Polyurea coatings are particularly effective in environments with harsh chemicals. Thanks to their strong urea linkages, they create a seamless and durable barrier that resists damage from petroleum-based and caustic substances. This structure not only prevents staining but also protects against water infiltration and corrosion, making polyurea an excellent choice for facilities handling a variety of chemicals.
Temperature fluctuations present another challenge. Sudden changes in temperature can cause coatings to crack or peel. To ensure resilience, coatings undergo thermal shock testing using MIL-STD 810 Method 503.7, which assesses how well they handle rapid temperature shifts – over 18°F within one minute. This testing is especially relevant for environments like cold storage facilities, where conditions frequently switch between freezing and ambient temperatures.
UV exposure is also a concern, especially in areas like skylights or outdoor loading zones. Prolonged sun exposure can degrade coatings over time. Using ASTM G154 testing, manufacturers simulate accelerated weathering to measure UV resistance. Polyurea coatings stand out here as well, offering resistance to fading, discoloration, and general degradation.
Moisture and humidity are constant threats, particularly in industries like food processing or chemical manufacturing. These conditions can lead to rust, blistering, or adhesion loss. Tests like ASTM D1654 evaluate coating performance against these challenges. Polyurea’s flexibility allows it to expand and contract with the substrate, maintaining its integrity even in freezing conditions and preventing water infiltration.
To assess chemical resistance more thoroughly, ASTM D1308 and D5402 tests are used to evaluate reactions such as discoloration, swelling, or deterioration. It’s a good idea to request test results tailored to your specific chemical exposure rather than relying on blanket resistance claims.
For facilities exposed to marine environments or road salt, ASTM B117 salt spray testing provides insight into how coatings perform under these conditions and highlights potential maintenance needs.
Finally, consider how combined stressors – like chemical exposure, UV rays, and temperature cycles – affect coatings. ASTM G26 testing incorporates water cycles alongside sunlight exposure, offering a more comprehensive look at how coatings hold up in real-world weathering scenarios.
To ensure the best coating selection, document your facility’s specific conditions, including chemical concentrations, temperature ranges, humidity levels, and UV exposure. Use this information to guide your choice and request matching test data to verify performance.
4. Check Safety and Slip Resistance
When choosing industrial floor coatings, safety should always come first – especially in areas where spills, moisture, or wet conditions are a regular concern. In the U.S., slips, trips, and falls are a leading cause of workplace injuries. That makes slip resistance a crucial consideration when selecting a coating. Understanding the standards for measuring slip resistance can guide you toward the right choice.
Slip resistance standards aren’t as straightforward as you might think. Many people assume that OSHA has strict rules about slip resistance, but that’s not the case. OSHA doesn’t enforce a specific standard, and the commonly referenced 0.5 static Coefficient of Friction guideline – originating from a 1970s University of Michigan study – is often misunderstood.
Instead, the American National Standard Institute (ANSI) A326.3-2021 offers the most widely accepted guidelines for hard surface flooring, including resinous coatings. According to this standard, level interior surfaces that are expected to be wet should have a wet Dynamic Coefficient of Friction (DCOF) of at least 0.42. For spaces with higher slip risks – like public showers, pool decks, or areas exposed to oils and grease – a wet DCOF of 0.50 to 0.55 is generally recommended.
Another reliable method for measuring slip resistance is the British Pendulum Test (BS 7976), which is recognized in over 50 countries. A Pendulum Test Value (PTV) above 36 typically indicates a low risk of slipping. These benchmarks can help you select coatings with the right safety features.
Polyurea coatings are particularly effective for improving slip resistance. They can incorporate broadcast aggregates, such as decorative quartz, or textured topcoats with additives like aluminum oxide. Aluminum oxide, a durable abrasive, provides long-lasting traction, unlike materials that wear down quickly. Textured polyurea topcoats create microtextures that enhance traction, significantly boosting the coefficient of friction even in areas prone to spills. These coatings also maintain their slip-resistant properties over time, even when exposed to industrial contaminants.
Polyurea doesn’t just rely on surface texture for safety. Its flexibility allows it to bridge cracks up to 1/8 inch, reducing the risk of trips. Additionally, polyurea coatings can be made non-porous and may include antimicrobial features, promoting a cleaner and more hygienic surface.
Before committing to a specific coating, it’s essential to test samples or small patches to ensure they meet your slip resistance needs. Work with your representative to choose the right textures and additives based on ANSI A326.3-2021 and the specific contaminants your facility faces.
If your project is outside North America, remember that slip resistance standards can vary by region. Always check the local requirements to ensure compliance. The ultimate goal is to match your coating’s slip-resistant properties to your environment’s demands and the applicable safety standards.

5. Prepare Surface and Check Substrate Compatibility
Getting the surface ready is essential because even the highest-quality coating can fail without proper preparation. Just like traffic loads and chemical exposure affect how well a coating performs, a well-prepared substrate is the foundation for long-lasting durability.
Start by evaluating the type and condition of the substrate. For new concrete, make sure it’s fully cured. Older surfaces may need extra attention, like removing sealers, oils, or any existing coatings. Check the substrate’s structural integrity using appropriate testing methods to uncover any potential adhesion problems.
Next, test for moisture and any contaminants that might interfere with bonding. Use standard moisture testing methods and confirm the levels align with the coating manufacturer’s recommendations. This step is critical to avoid adhesion issues. Additionally, create the right surface profile for mechanical bonding based on your coating manufacturer’s specifications.
Mechanical treatments, such as shot blasting or diamond grinding, can help remove contaminants, create the proper surface texture, and ensure uniformity. Be sure to control dust during this process for a clean work environment.
If there are significant cracks, repair them using approved techniques. Remove oils, grease, and other contaminants thoroughly to ensure the coating adheres properly. For deeply embedded stains, you may need specialized treatments to clean the surface effectively.
Check the substrate’s alkalinity and, if necessary, adjust it using acid etching or neutralizing solutions. Also, maintain the recommended temperature and humidity levels during preparation to prevent condensation and support proper curing.
Finally, clean the surface thoroughly to eliminate all dust and debris. A spotless substrate is crucial for a strong bond and a flawless coating application.
6. Plan Installation Time and Cure Times
Once the substrate is ready, it’s time to schedule the installation in a way that reduces downtime and ensures the coating performs as expected. Timing is everything here. For example, fast-curing systems like polyurea and polyaspartic coatings allow foot traffic within hours and even vehicle traffic by the next day. This quick turnaround lets you align the project schedule with your facility’s operational demands.
To keep things running smoothly, consider dividing the work into sections. This approach allows certain areas of your facility to remain operational while coatings are applied elsewhere. It’s especially useful for critical areas, which can be tackled during planned maintenance or slower production periods. This method ensures the curing process isn’t rushed or compromised.
Don’t forget to allocate extra time to maintain stable environmental conditions during both installation and curing. These controlled conditions are key to achieving the long-term durability and performance the coating is designed to deliver.
7. Calculate Maintenance and Long-Term Costs
When thinking about total ownership costs, it’s essential to look beyond the initial installation. Consider daily upkeep, repairs, and recoating over the floor’s entire lifespan.
Daily maintenance costs can add up over time, but polyurea coatings keep things simple. All it takes is regular sweeping and weekly mopping with a pH-neutral, non-abrasive cleaner – no need for harsh chemicals or specialized cleaning tools. This straightforward routine helps keep labor costs steady and avoids the expense of additional equipment.
Polyurea also stands out for its durability. It’s four times stronger and ten times more flexible than epoxy. Even after 3,800 hours of UV exposure, it retains 80% of its strength, reducing the likelihood of unexpected repairs.
Unlike epoxy and urethane coatings, which often require recoating every 3–5 years, polyurea can last over 10 years – or even 20 to 30 years with proper care. This extended lifespan means fewer recoating projects over the life of a facility, which translates to considerable savings in both time and money.
Simple preventive measures can further stretch the life of your coating. Using entryway mats, machinery floor protectors, and additional protective layers can help minimize wear and tear at a low cost.
While polyurea installation costs range from $7 to $13 per square foot as of 2025, this upfront investment is offset by its lower maintenance requirements and long-lasting performance.
Quick repairs are key to keeping costs down. Addressing small damages like chips, scratches, or cracks right away with appropriate fillers can prevent water infiltration and avoid more serious issues. Training maintenance staff to spot and fix these minor problems promptly can save you from costly repairs down the line.
When calculating total ownership costs, don’t forget to include regular inspections, an emergency repair budget, and planned recoating intervals. Factor in labor costs for cleaning crews, downtime during major repairs, and the potential productivity losses caused by floor failures. Often, a coating with a higher initial price but minimal maintenance and decades of durability offers the best return on investment for industrial facilities.
8. Review Warranty and Quality Standards
Once you’ve tackled installation and maintenance, it’s crucial to dive into warranty and quality standards. These not only protect your investment but also reduce potential repair headaches down the line. Let’s break down what you need to know about warranties and industry standards to ensure your coating choice is a smart and secure one.

Red Flags to Watch Out For
Be cautious of warranties or contractors that raise concerns, such as:
- Vague warranty terms or excessive exclusions.
- Short warranty durations.
- Contractors who lack proper certifications or avoid discussing industry standards.
- "Lifetime" warranties that exclude normal wear, UV damage, or chemical exposure – these offer little real protection.
Documentation Is Key
Keep detailed records of the entire process to support your warranty coverage. This includes:
- Surface preparation steps.
- Environmental conditions during application.
- Cure times.
- Any deviations from the original specifications.
Proper documentation ensures you’re covered in case of disputes or warranty claims.
