When it comes to furniture and fixtures, it's common practice to apply a sealant near the end of construction. Not only do sealants provide protection (to varying degrees), but they also often improve the appearance of the finished surfaces.
But there are many sealant options to choose from, especially for ubiquitous materials like wood, which benefit from a wide selection of varnishes, waxes, and other types of finishes. Among these options is epoxy resin, a transparent sealant that starts off as liquid and hardens to a clear solid.
In this article, we'll discuss the advantages and drawbacks of using epoxy resin on your surfaces, whether for a countertop, bar top, chair, table, or any other type of furnishing.
The pros and cons of an epoxy finish
Here are the pros and cons of an epoxy finish, along with strategies to mitigate the drawbacks:
Pros of an epoxy finish
#1: High durability and resistance to damage
Epoxy finishes are highly resistant to scratches, dents, and impact, making them ideal for surfaces that experience heavy use. This is especially helpful for environments with a higher risk of physical damage, such as kitchens, dining rooms, and bars.
#2: A waterproof bond and moisture protection
Once cured, epoxy is waterproof, preventing damage from spills or moisture, which is especially beneficial for tabletops. This makes cleaning easier and prevents staining from liquids and other substances.
#3: A protective barrier resistant to chemicals
Epoxy can withstand exposure to various chemicals, oils, and solvents, making it suitable for workshops or kitchens. This resilience provides ample time to clean up after cooking or accidental spills.
#4: Aesthetic appeal, including a high gloss finish
Epoxy provides a sleek, glossy finish that enhances the appearance of wood and other surfaces. It can also be colored or mixed with additives for unique effects.
#5: Easy maintenance and simple cleaning
Epoxy surfaces are easy to clean and maintain, often requiring just soap and water.

#6: Extensive sealing properties that account for gaps and cracks
Epoxy can fill in imperfections, gaps, and cracks in surfaces, providing a smooth, even finish. Not only does this make it easy to apply to almost any suitable material, but it also means epoxy repairs are convenient as well.
Cons of an epoxy finish—and how to mitigate them
#1: Sensitivity to UV light
Prolonged exposure to UV light can cause epoxy to yellow and degrade over time. This is more likely to occur with lower end epoxy products.
To mitigate: Use UV-stabilized epoxy formulations designed to resist yellowing, or apply a UV-resistant topcoat to protect the surface.
You can also avoid the issue entirely if the project is kept indoors. For outside projects, it's a good idea to keep your epoxy shaded from the sun, either through natural means like trees or by providing a shelter.
#2: Long cure time
Depending on the formulation, epoxy can take several hours to days to cure fully. In the grand scheme, this isn't very longespecially since well-cured epoxy can last for many years—but it still means some care must be taken to ensure adequate curing time.
To mitigate: Plan your project timelines accordingly and consider using faster-curing epoxy products if needed.
#3: Potential for bubbles in the finish
Air bubbles can form during the mixing and application process, leading to an uneven finish.
To mitigate: Use a heat gun or torch to remove bubbles immediately after pouring. Mix slowly to minimize air introduction. When using a drill, keep the bit low in the mixing container to avoid pulling in air.
For those who want to go the extra mile, consider using a vacuum chamber to degas the epoxy before pouring.

#4: Temperature sensitivity prior to hardening
High humidity or extreme temperatures can affect the curing process and the final result.
To mitigate: Work in a climate-controlled environment, ideally at 70-75°F with humidity levels below 60%. Ensure surfaces are prepped and conditioned appropriately.
#5: Mistakes lead to brittleness
While epoxy is durable, it can be brittle if not mixed correctly, leading to cracking under heavy stress.
To mitigate: Ensure proper mixing ratios and consider flexible epoxy formulation designed to withstand stress without cracking.
In the end, the positive aspects of epoxy outweigh the negatives
By understanding the pros and cons of epoxy finishes and implementing strategies to mitigate the drawbacks, you can enjoy the many benefits of epoxy while minimizing potential issues.
Epoxy resin: Not invincible—but as close as it gets.
As with any material, epoxy resin has both pros and cons. But no other sealant has so few weaknesses, and that's what puts epoxy above all other options when it comes to being a finish for high-traffic fixtures and furniture such as countertops, table tops, and bar tops. This is especially true for premium epoxy resins, such as our UltraClear products.
You can find our UltraClear Epoxy products on the following pages:
- UltraClear Bar & Table Top Epoxy: The classic choice for bar tops, countertops, and table tops. Rock-solid, waterproof, and crystal-clear.
- UltraClear Deep Pour Epoxy: Our deep pour casting resin. Ideal for thick layers, such as those needed for river tables.
- UltraClear Art & Craft Epoxy: Our arts and crafts resin, designed for smaller artistic endeavors which typically involve resin molds and require a bit more fluidity than bar top epoxy.
With high chemical and physical resistance, epoxy can withstand and endure many forms of wear and tear without breaking a sweat or showcasing any cosmetic damage.
Plus, in addition to its ease of application, it also requires little upkeep to maintain its pristine appearance. With a high-quality epoxy finish, you can expect a minimum lifespan of 7 years, with no need for reapplication. Beyond that, it's a breeze to renew that coating, requiring only a light sanding and a fresh layer of epoxy.
