Epoxy Resin Flooring: Issues & Fixes


1. Battle Bubbles


Dealing with epoxy resin air bubbles can be disheartening, especially when they surface soon after an otherwise successful installation. Don't just surrender, though; there's an easy fix! They often result from trapped air or moisture within the epoxy. To resolve this concern:


Solution: If you only catch the bubbles after installation, you might have to gently scrape the target area and reapply the resin. Prepare your surfaces properly always! Check for moisture, and always apply epoxy under optimal environmental conditions.

Alternatively, if you can spot the bubbles while the epoxy is still curing, the fix is even easier! Use a heat gun or blow torch lightly on the affected areas and the bubbles will start to dissipate.


2. Combat Curing Concerns:


Inconsistent curing, where some areas fully cure while others remain tacky, typically occurs due to temperature fluctuations. This can be especially annoying for contractors working on tight project deadlines! To attain uniform curing:


Solution: Maintain a consistent application area temperature, ideally between 70-80°F (21-27°C). Consider placing a heater in the installation space to regulate the temperature.

Stick to the manufacturer's prescribed curing time and conditions! Patience is a virtue during epoxy resin curing. Even though curing is the last step in any successful epoxy resin installation, it actually starts with mixing. You'll need to meticulously measure your solution ratios, mix slowly and carefully, and install the resin carefully.


3. Confront Epoxy Resin Cracks:


Cracks aren't just blemishes, they might be a sign of deeper epoxy resin issues. Cracks usually form from an improper resin mix. Generally, it's either because the resin been mixed poorly or the ratios are wrong. To avoid and remedy cracks:


Solution: Precisely measure and mix epoxy components as per the manufacturer's guidelines. As you'll see, most issues during epoxy installation can be prevented in the first few steps of a project! Apply the carefully mixed epoxy resin in thin, even coats to prevent excessive buildup and stress on the surface. Allow every layer of resin to cure fully before applying a new layer.

Cracks may also emerge due to abrupt temperature changes, particularly during curing. Maintain a stable ambient temperature in your workspace by using space heaters, closing windows, or providing shade.


4. Tackle Epoxy Resin Yellowing:


Epoxy resin is known to begin to yellow when exposed to UV rays, especially (but not only) in outdoor settings. To prevent yellowing:


Solution: Employ UV-resistant epoxy formulations for outdoor projects. Most polyaspartic or fast-cure epoxy resin solutions come with the added benefit of increased UV-resistance. Either apply a clear UV-resistant topcoat, like our strong Fast Cure solution, or add as much shade as possible.

Professional tip: use traditional epoxy resin as a base for your epoxy resin system, then a polyaspartic resin topcoat. That way you get the best of both worlds!


5. Handle Peeling Epoxy Resin:


Like many of your epoxy resin issues, epoxy resin floor peeling is entirely preventable! Generally, it'll stem from poor adhesion & bonding. To ensure a robust bond:


Solution: Thoroughly clean and grind the substrate to establish an appropriate adhesion surface. You need your foundation to be set up to bond with the epoxy resin! Use a high-quality epoxy primer compatible with your selected epoxy system. Check for moisture before applying epoxy resin.

Like with all things, an ounce of prevention is worth a pound of cure. So, prepare your surfaces carefully, and thoroughly.


6. Preserve Your Epoxy:


The beauty of epoxy floors are their ease of maintenance. Some simple routine maintenance is all you need to keep its shine lasting! Without some simple maintenance, dirt and grime can build up, and sometimes lead to long-term issues with your floors.


Solution: Regularly clean the surface with mild detergent and warm water. That's all you need! Don't use any abrasive or harsh chemicals that can damage the epoxy. Epoxy is seamless when installed correctly, so you don't need to be rough with it to fight off grime. Reapply a clear topcoat as necessary to safeguard the surface.




Don't be intimidated by epoxy resin flooring! Not only are they the best bang for your buck, especially as a contractor, but any issues that may arise are easy to solve. You can prevent most any epoxy problems and achieve exceptional results with the right knowledge and solutions. Remember, prevention is key, and formal training can make all the difference.
