Epoxy resin is an effective solution to create durable, glossy finishes for home improvement projects. But the caveat to this all-purpose material is its tendency to yellow over time. Have you noticed your once-clear or brightly colored epoxy turn to a slightly off-putting shade of yellow? If so, you’re not alone. This process, often a deal-breaker for many, can make your hard work appear old and tarnished. Moreover, it might lead you to question – Can I get epoxy resin that doesn’t yellow over time?
To answer this question, let’s first understand why epoxy resin yellows. The primary cause of epoxy turning yellow is exposure to UV light. In addition to UV-resistant epoxy, there are various types of epoxy coatings available. Learn more about them in our article Different Types of Epoxy Coating. Other factors like excessive heat, water, or oxygen can also contribute to the process. While exploring epoxy resin, it’s also useful to understand the difference between epoxy coatings and epoxy paint, which you can read about in our detailed comparison What Is the Difference Between Epoxy Coating and Epoxy Paint?. These elements degrade the pigments and polymers in the epoxy resin, causing oxidation and consequent discoloration.
Are There Any Types of Epoxy Resin That Are Resistant to Yellowing?
Yes, and there’s great news for homeowners! Several epoxy resins come with UV inhibitors and HALS (hindered amine light stabilizers), delaying the yellowing process. Opt for a resin with either of these features, or select one with both. For example, The Epoxy Store’s Clearcast 7050 dramatically increases its protection against yellowing.

Does Yellowing Affect Durability?
The yellowing of epoxy does not necessarily indicate a decline in its physical durability or structural integrity. Epoxy resin can yellow over time when exposed to UV light or heat, which is a cosmetic change that affects its appearance rather than its strength. High-quality epoxy resins are formulated to be UV resistant to minimize this effect, but even then, some yellowing may occur with prolonged exposure. While discussing epoxy’s durability, it’s important to know the scenarios where epoxy might not be the best choice. Learn more about these situations in our article When Should You Not Use Epoxy?. It is important to note, however, that while yellowing itself doesn’t weaken the epoxy, prolonged UV exposure that causes yellowing can lead to other forms of degradation such as chalking or brittleness.
How to Fix Yellowed Epoxy
Fixing yellowed epoxy can be achieved through:
- Using an automotive polish, such as Meguiar’s NXT Generation Tech Wax, to restore gloss and remove blemishes.
- Using a UV light, if the epoxy has only lightly yellowed.
In severe cases, complete removal and replacement of the epoxy may be necessary. In that case, it is best to call professionals like All Painting that can help. For more insights into the longevity and maintenance of epoxy resin, check out our in-depth guide on How Long Does Epoxy Coating Last?.
Conclusion
To sum it up, while the yellowing of epoxy resin is a prevalent problem, it is not without solutions. Ensuring appropriate storage and usage conditions, choosing UV-resistant epoxy, or selecting an alternative can effectively minimize yellowing. Therefore, don’t let the fear of yellowing deter you from exploring the versatile world of epoxy resins.

Frequently Asked Questions
What causes epoxy resin to yellow in Vancouver homes?
Epoxy resin yellows primarily due to UV light exposure and is also accelerated by heat and chemical reactions over time. In Greater Vancouver homes, epoxy floors and countertops near south-facing windows or skylights are especially vulnerable to yellowing due to summer UV exposure. Even indirect sunlight through Vancouver’s overcast skies contains enough UV radiation to gradually degrade standard bisphenol-A epoxy resins, causing an amber discolouration.
What is the best non-yellowing epoxy for garage floors in BC?
For garage floors in British Columbia, aliphatic polyurethane or polyaspartic coatings are the best non-yellowing alternatives to standard epoxy. These coatings offer superior UV stability and will not amber even with direct sunlight exposure through garage windows or open doors. In Greater Vancouver, professional floor coating companies often recommend a hybrid system using an epoxy base coat for adhesion topped with a polyaspartic clear coat for UV protection and durability.
How much does epoxy floor coating cost in the Greater Vancouver area?
Professional epoxy floor coating in Greater Vancouver typically costs between $6 and $12 per square foot, depending on the system used and surface preparation required. A standard two-car garage in the Lower Mainland averages $3,000 to $5,000 for a full epoxy system with flake broadcast. Premium non-yellowing polyaspartic systems cost $8 to $15 per square foot but offer superior UV resistance and faster cure times, which is advantageous during Vancouver’s limited dry-weather windows.
Can yellowed epoxy be repaired without full removal?
Yes, yellowed epoxy can often be restored without full removal by applying a non-yellowing polyurethane or polyaspartic top coat over the existing surface after light sanding. This is a common and cost-effective repair approach used by professional painters and floor coating specialists in Greater Vancouver. The new clear coat blocks UV light and restores a crystal-clear appearance. However, if the existing epoxy is peeling or has adhesion issues, full removal and reapplication is necessary.
Is epoxy resin safe for kitchen countertops in BC homes?
Food-safe epoxy resins are available and popular for kitchen countertops in British Columbia homes. Once fully cured, which takes 7 to 14 days, quality epoxy resins are inert and safe for food contact. For kitchen applications in Greater Vancouver, choose a BPA-free, non-yellowing epoxy specifically rated as food-safe, and ensure proper ventilation during application. Professional painters in Vancouver recommend UV-stable formulas for countertops near windows to prevent yellowing over time.
