Polished Concrete Flooring vs Epoxy Flooring

6 Key Factors to Keep in Mind When Comparing Their Values

If you’re diving into the world of flooring options, whether it’s for a residence, retail spot, or a business space, your decision might boil down to polished concrete versus epoxy flooring. Lucky for you, this is the perfect place to discern the differences.

While it’s natural to lean towards the most cost-effective solution, particularly when you’re budget-bound, flooring choices demand a broader perspective. Sometimes, an option that appears budget-friendly initially could rack up costs in the long run due to maintenance or other associated concerns. This cost-value balance is applicable across many products and services, not just floorings.

Therefore, the spotlight should be on the overall value rather than just the upfront cost. With polished concrete and epoxy flooring in the fray, it’s essential to understand the nuances that determine their long-term worth. This piece aims to elucidate some critical points to help you arrive at an informed choice between the two.

So, let’s delve deeper into 6 paramount factors that can guide you in evaluating the comprehensive worth of polished concrete flooring in contrast to epoxy flooring.

• Cost over Time

In weighing the long-term benefits of various flooring alternatives, it’s logical to begin with the examination of their costs spread across time. At a cursory look, epoxy flooring might appear to be more pocket-friendly compared to polished concrete. For example, if you’re considering flooring for a commercial location spanning more than 200 m2, the immediate expense of epoxy flooring can initially appear to be on the lower side, especially if you’re contemplating just a standard commercial-grade epoxy. However, if your requirements lean towards a pharmaceutical-grade epoxy (like those needed for storing dietary supplement ingredients), the pricing equation changes. In such scenarios, epoxy could surpass the cost of polished concrete, especially if you’re aiming for a lighter shade necessitating multiple layers. It’s also crucial to note that epoxy flooring often demands considerably higher recurrent maintenance.

For short-term flooring solutions, epoxy might indeed be the way to go. However, the intrinsic nature of epoxy flooring leans towards being transient. This is attributable to its susceptibility to wear and tear, necessitating eventual reapplication or complete replacement. Factors like chipping, vulnerability to scratches, and potential ‘delamination’ (especially if the foundational surface wasn’t aptly prepared, causing large chunks of the coating to peel off) underscore this point. Simple actions like moving equipment across an epoxy floor might result in noticeable damage, and attempts at spot repairs often culminate in uneven, conspicuous patches.

Hence, the long-term financial implication of epoxy flooring, though less burdensome initially, will invariably require additional investments for re-coating to uphold its aesthetics. In juxtaposition, polished concrete stands out as more resilient, boasting a notably extended lifespan. Its longevity often surpasses that of epoxy flooring by a considerable margin, eliminating the frequent need for refurbishments. While the final decision between epoxy and polished concrete should align with specific needs and tastes, a holistic assessment of costs over time generally tilts the balance in favor of polished concrete for superior lifetime value, says Jeremy Lesher, Co-Owner & Product Manager of Bluegrass Foundation Repair.

• Maintenance and Cleaning

When deliberating over flooring options, one shouldn’t overlook the aspects of upkeep and cleaning. It might seem trivial initially, but cleaning regimes, along with associated maintenance, can accumulate costs in terms of labor, resources, and time. This makes it a pivotal consideration when evaluating long-term value.

One noticeable drawback of epoxy flooring, especially when compared to polished concrete, is its demanding cleaning regimen. Epoxy floors can be challenging to clean, primarily because numerous cleaning agents threaten to peel off its surface. Consequently, one usually resorts to specific, often acid-based, cleaners tailored for epoxy surfaces. Besides the financial implications of these specialized cleaners, they also necessitate the use of protective gear, encompassing clothing, goggles, and respiratory aids. This inevitably results in extended time and labor for cleaning. Additionally, if mishandled, these chemicals could be detrimental to health.

Epoxy floors also present challenges in removing paint overspray and, as highlighted earlier, are susceptible to scratching, peeling, and, in severe cases, delamination.

In stark contrast, concrete flooring showcases commendable ease of upkeep and cleanliness. Simple measures, like employing hot water or a dry dust mop, suffice to rid polished concrete of dust and debris. While one should steer clear of extremely alkaline or acidic agents, a balanced pH-neutral cleaner is apt for concrete surfaces. More often than not, mere hot water does the trick for polished concrete.

Drawing parallels in the cleaning and maintenance realm, polished concrete has a clear edge over epoxy flooring. With its innate resistance to scratches—thanks to the rigorous hardening during polishing—concrete flooring emerges as the less demanding option. The fact that polished concrete is inherently non-delaminable, given its absence of any topical coating, further consolidates its position. While polished concrete befriends simple hot water for cleaning, epoxy flooring mandates specific chemical treatments coupled with safety precautions, says George Alvarez, Owner of Expert Epoxy Flooring.

• Health and Safety Implications

Shifting focus to protective measures naturally segues into a paramount aspect of flooring choice – health and safety. The safety stakes associated with flooring shouldn’t be undermined, and it’s essential to highlight that several epoxy floor variants might carry potential health ramifications. It’s worth clarifying that when epoxy flooring is installed correctly, it’s generally regarded as safe. Yet, the issue arises with epoxy’s high VOC (volatile organic compounds) content.

A brief chemistry detour: epoxy flooring comprises two main ingredients – a hardener and resin. Their chemical interaction gives birth to VOCs. Epoxy’s distinct scent, akin to ammonia, is attributed to these VOCs. The more the hardener, the stronger the fumes emitted. Especially in spaces related to food ingredient storage, only pharmaceutical grade epoxy meets the safety bar. This is due to the potential of fumes permeating goods and infrastructure, leading to contamination. Hence, many commercial infrastructural projects demand the application of water-based epoxy, if any.

It’s essential to note that some epoxy variants have relatively lower VOC concentrations. Water-based epoxies, for instance, emit a milder smell. However, they tend to compromise on durability when compared to their solvent-based counterparts. An absence of a strong scent doesn’t validate a VOC-free environment, and even minimal VOC levels can pose health threats during the installation phase. Hence, protective attire remains imperative even with these “safer” epoxies.

The significance of VOCs is magnified in areas with limited ventilation, such as basements or garages. And while the appropriate installation safeguards against many risks, one shouldn’t be oblivious to potential VOC-related threats.

Elevated VOC exposure is notorious for various health issues. From skin irritations and allergic reactions to respiratory challenges reminiscent of asthma, VOCs’ impact is wide-ranging. Whether inhaled or through direct skin or eye exposure, prolonged exposure heightens the risks.

While the aroma emanating from epoxy diminishes over time, during the installation, it can be overpowering. On rare occasions, epoxy can induce chemical burns, further accentuating the need for protective gear. Prolonged VOC exposure might also lead to “epoxy sensitisation,” where every subsequent epoxy exposure worsens symptoms, potentially developing into full-blown allergies.

The US Centers for Disease Control and Prevention (CDC) has drawn correlations between certain epoxy chemicals and fertility disruptions, birth anomalies, and even tragic outcomes like miscarriages and stillbirths.

The takeaway isn’t that epoxy floors are universally hazardous or devoid of safety measures. It also isn’t indicative of every individual reacting adversely to epoxy or that all epoxy is laden with perilously high VOCs. However, the mere existence of such risks necessitates informed decision-making, particularly for those with existing health concerns or compromised immunity. Thorough research and awareness are pivotal when considering epoxy for your space, says Robert Fields, Owner of ATX Stained Concrete.

• Longevity

Durability undeniably stands at the forefront when appraising the comprehensive value of flooring options, and it’s clear that polished concrete generally trumps epoxy in this domain. While we touched upon the longevity advantages of polished concrete earlier, it’s worth delving deeper into the durability nuances of both these choices.

It’s crucial to understand that epoxy’s durability can exhibit variances based on its type. Water-based epoxies, for instance, often lag in durability when juxtaposed with their solvent-based counterparts. An inherent downside of both water-based and solid-based epoxies is the heightened maintenance frequency, leading to earlier replacements. This not only incurs extra effort and expenditure but, in commercial settings, implies recurring costs that could have been avoided.

Furthermore, the susceptibility of unfinished and certain cheaper epoxies to UV rays can lead to discoloration or yellowing. This factor becomes particularly pertinent in outdoor or sunlit indoor areas.

Reflooring has its own set of challenges. Both polished concrete and epoxy demand specialized expertise for flawless installation. Given the frequency of refurbishment epoxy might necessitate, the preparation involved, such as thorough cleaning, old coating removal through grinding, and hole repair, can be labor-intensive. While epoxy’s application isn’t particularly time-consuming, its drying span can extend across days. Not to mention, post-application, it requires a curing period of around 7-14 days, contingent on ambient conditions. Such extended durations without foot traffic can pose operational challenges, especially in commercial spaces.

Moisture compatibility is another crucial dimension. Epoxy’s bond with concrete can weaken in damp conditions, leading to issues like peeling, lifting, and even ripple formations. Uneven substrates exacerbate these ripple concerns, emphasizing the need for a level surface before epoxy application.

Moisture-related challenges aren’t confined to epoxy. The impermeable nature of epoxy can trap moisture, culminating in problems like delamination or the development of “bubbles” and floor peeling. Severe buckling, arising from trapped moisture, might mandate repairs or even complete redoing of the epoxy layer.

Contrastingly, polished concrete, when adequately sealed, showcases commendable water resistance. Its breathable nature bolsters its resilience against moisture-induced challenges, ensuring it stays durable for longer.

Ultimately, the choice between polished concrete and epoxy might be influenced by the specific setting of the floor. However, as an overarching observation, polished concrete usually promises enhanced longevity.

• Location

For both polished concrete and epoxy flooring, maintaining a clean and dry environment significantly reduces potential hazards like trips or slips.

The specific setting of your flooring plays a pivotal role in its durability and functionality. As highlighted before, epoxy flooring is susceptible to damage from heightened moisture levels, whereas polished concrete flaunts superior adaptability across various environments due to its moisture-resisting nature.

In high-footfall areas, it’s crucial to remember that epoxy, being a topical coating, is prone to scuffs, scratches, and eventual wear. This wear might necessitate periodic repairs or replacements. In contrast, polished concrete is intrinsically robust against frequent foot traffic, providing a longer service life.

For specialized indoor areas like garages, specific epoxy variants tailored for conditions like hot tyre contact exist, but these are generally pricier. In such scenarios, polished concrete might offer a cost-effective and durable solution. In commercial or industrial zones with frequent movement of carts or rolling equipment, it’s essential to recognize that epoxy floors can sustain damage from such traffic.

When zeroing in on either polished concrete or epoxy flooring for a distinct setting, it’s prudent to delve deeper into research. Identifying the perfect flooring for your particular environment, a concept known as ‘fit for purpose’ in the flooring realm, ensures optimal utility and longevity.

• Appearance

The visual appeal is undeniably a vital parameter when oscillating between polished concrete and epoxy flooring choices. Depending on your environment – be it residential, commercial, or industrial – aesthetics might either top your priority list or take a backseat.

A pivotal point regarding epoxy is its permanence post-curing. Altering its appearance becomes a challenge, requiring a strong commitment to the chosen style for the foreseeable future. Conversely, given the ephemeral nature of epoxy flooring, it might suit spaces where periodic floor revamps are envisioned or where a short-term flooring solution suffices.

For polished concrete, the inherent colour becomes a fixed variable, especially if you’re working with pre-existing concrete. However, for freshly sourced concrete, there’s a wide palette of colour mixes to choose from. Furthermore, by varying the polishing intensity, you can modulate between matte and glossy finishes.

One striking distinction between the two is their light reflectivity. Polished concrete excels in this aspect, drastically elevating the room’s luminosity. This characteristic, combined with its adaptability between high-shine contemporary finishes to matte industrial ones, makes polished concrete a versatile and aesthetically superior option.

Epoxy flooring, however, leans towards a more subdued matte appearance or, when glossy, can exude an artificial, plasticky sheen. Thus, it’s perceived as less captivating. For spaces where aesthetics aren’t paramount, epoxy might suffice. However, if the goal is to manifest a chic, contemporary ambiance, polished concrete undoubtedly emerges as the more visually appealing contender, says Shlomo Cherniak, Owner of Cherniak Handyman Services.

The Next Steps

After meticulously evaluating your specific flooring requisites and tastes, the next step involves deciding between polished concrete and epoxy flooring. Reflecting on the six crucial dimensions we highlighted—cost longevity, upkeep dynamics, health implications, resilience, setting suitability, and visual appeal—you might discern a tilt in favor of polished concrete. While epoxy might allure with its upfront affordability, a holistic examination spanning long-term costs and comprehensive value often positions polished concrete as a superior alternative. Indeed, there are contexts where epoxy might be a more fitting choice, contingent on your prioritized criteria. Yet, when gauging through the lens of the discussed six parameters, polished concrete undeniably boasts several intrinsic merits over epoxy flooring.
