Primaloc Answers: What Is the Best Bar Top Sealant?

A bar top installation is a serious endeavor. In part due to their size—which is typically larger than other decorative elements and fixtures—bar tops tend to require more resources, time, effort, and finances than less extensive projects.

Furthermore, bar tops often become the focal point of a space, designed to hold up under regular use while providing a gathering spot for social interaction, whether among friends or patrons.

Given these characteristics, ensuring that your bar top is well-sealed is crucial not only for its preservation and protection but also to maintain its visual appeal and welcoming ambiance.

In this guide, we'll explore a variety of popular sealants, highlighting their strengths and applications. Afterward, we'll offer our recommendation for the ideal bar top sealant choice.

Common Types of Bar Top Sealants

Sealing your bar top is an essential step to ensure its longevity and maintain its quality. How much use your bar top will endure helps determines the type of sealant you should apply.

An effective sealant offers resistance to moisture and shields against various forms of damage, including scratches and dents, while also preserving or enhancing the bar top's natural look.

Currently, a wide array of sealants exists for bar top applications, including varnishes, oil-based sealants, polyurethanes, and bar top epoxy resins, each serving to protect and sustain the bar top's aesthetic and structural integrity.

Next, we'll take a look at some common bar top sealants, including:

  • Epoxy Resins
  • Hardwax Oils
  • Tung Oils
  • Polyurethane Varnishes
  • And Lacquer Varnishes

Let's begin from the top, with epoxy resin.

Bar Top Sealant #1: Epoxy Resins

First up is epoxy resin. This sealant is a two-component system consisting of resin and hardener which, when mixed, undergo an exothermic reaction that initiates a hardening process called curing. Designed for application on surfaces such as bar tops—where it is typically poured on—epoxy resin levels itself to form a solid, ultra-smooth, and durable finish.

For sealing bar tops, epoxy resin stands out as the premier choice. Its combination of a hard, waterproof surface, with its clarity and high-gloss finish, provides an unmatched lifespan compared to other types of sealants. It's universally adaptable to most bar top materials, making it a versatile option for various projects.

Simple application, low-maintenance, and cost-effective.

The application process of epoxy resin is straightforward, and once it has cured, it becomes simple to clean and maintain. It offers sufficient heat resistance for everyday scenarios, though direct contact with very hot items should be avoided.

Despite its higher initial cost, epoxy resin proves to be more economical in the long run. Other sealants may require frequent reapplication or maintenance due to wear or reduced effectiveness, leading to additional expenses over time.

Choosing epoxy resin means opting for the highest quality with a view toward long-term savings and minimal maintenance, making it the optimal selection for those prioritizing durability and aesthetic appeal.

Bar Top Sealant #2: Hardwax Oils

Hardwax oil offers a straightforward solution to achieve a moderate level of protection against moisture and scratches for your surfaces. For wood, it'll maintain natural aesthetics, providing a matte or satin finish without the plastic-like sheen common with sealants like polyurethane.

Easy to apply after some sanding

The application process for hardwax oils is user-friendly, suitable even for novices, though proper sanding of the wood surface is essential before application. These oils are also more environmentally friendly, with low volatile organic compounds (VOCs) released during use and none after the solvents have evaporated.

However, occasional reapplication will be necessary

Nonetheless, hardwax oil finishes do necessitate periodic reapplication, the frequency of which depends on the usage intensity of the treated surface. Regular inspections of your bar top will help determine when a new coat is necessary.

In terms of cost, hardwax oil is generally more affordable compared to other sealants, and even with the need for multiple layers, the initial expense remains reasonable. However, the ongoing requirement for reapplication introduces additional costs over time.

Therefore, if you prefer a maintenance-free solution or wish to avoid recurring expenses, hardwax oil might not align with your needs.

Tung oil being applied to a wooden surface.

Bar Top Sealant #3: Tung Oils

Tung oil is favored for its water-resistant qualities and attractive finish, which uniquely doesn't darken with time as some other oils might.

When applied to wooden surfaces, it enhances their natural color, providing a richer, almost dampened appearance that many find aesthetically pleasing.

Economical but low-level protection.

Yet, in terms of durability and protection, tung oil falls short compared to other finishes mentioned here. It offers minimal physical protection, making it less than ideal for high-traffic areas such as bar tops or tables. Its use is more appropriate for environments exposed to moisture and humidity, like on boats or watercraft, where its water-resistant properties are beneficial.

In terms of cost, tung oil is among the most economical choices, though it's important to note that it may not deliver the level of protection or longevity desired for a bar top application.

Bar Top Sealant #4: Polyurethane Varnishes

Polyurethane, similar to epoxy, is a type of polymer that applies in a much thinner layer, allowing the natural texture of surfaces to show through.

In terms of durability, polyurethane ranks as the second most robust option on this list, with only epoxy resin surpassing it in strength. Like epoxy, it can be polished and buffed, offering a sturdy protective layer.

However, there are drawbacks to using polyurethane. It forms a less substantial bond compared to epoxy, and this weaker bond might loosen over time. Additionally, it has a natural tendency to yellow as it ages.

Polyurethane is best suited for indoor environments. Its performance on outdoor surfaces is compromised due to vulnerability to weather elements, moisture, humidity, and UV radiation. Though there are UV-resistant polyurethane versions available, these are not recommended for outdoor use because they still fall short in withstanding other environmental factors effectively.

Lacquer being applied to a wooden surface.

Bar Top Sealant #5: Lacquer Varnishes

Lacquers are commonly applied to wood surfaces through spraying, offering a layer of moisture and scratch resistance. Pre-catalyzed lacquers are preferable for their ease of application and reliable protective qualities.

The use of lacquer results in a glossy finish but tends to yellow as it ages, which could be a downside for those looking to maintain the original coloration of their surface.

Application of lacquer requires caution due to its toxic nature; spraying should be conducted with adequate ventilation and appropriate safety equipment to minimize health risks—in other words, be sure to wear a suitable mask or respirator while applying it.

Lacquer can embelllish minor blemishes.

Surface preparation is crucial when working with lacquer, as it unforgivingly highlights any surface imperfections. Ensuring the wood is smooth and thoroughly sanded is essential to achieve a flawless finish.

In terms of cost, lacquer is generally more affordable than epoxy, though it may require periodic reapplication and offers less overall protection. It is best recommended for areas of low traffic or where the bar top will experience minimal wear, making it a practical choice for settings with lighter use.

What Is the Best Bar Top Sealant?

Now that we've reviewed the 5 leading contenders for bar top sealants, we're able to determine which one is superior in most situations.

Epoxy resin emerges as the frontrunner. Despite its higher initial cost compared to other alternatives, an epoxy resin finish for bar tops offers unparalleled benefits: enhanced durability, robust protection, and an aesthetically pleasing, crystal-clear appearance that outperforms all other contenders.

Opting for a high-quality bar top epoxy not only yields the finest outcomes but also proves to be the most economical in the long run, saving significant time and resources.
