How to Fix Yellow Epoxy Floors

In this guide, we will walk you through how to fix yellow epoxy floors and restore them to their original luster. Let’s dive in.

Can You Fix the Yellow Epoxy Floors?

If you have yellow epoxy floors driving you crazy, you’re not alone. While epoxy floors are incredibly durable and long-lasting, they can begin to yellow over time due to exposure to sunlight or improper maintenance. Luckily, solutions to this problem don’t involve replacing the entire floor.

There are professional services available that can restore your epoxy floors to their former glory, using special techniques and materials to remove the yellowing and restore the original color.

If you’re feeling handy, DIY options are also available, such as using a special epoxy painting kit to cover up the yellowed areas. With the right tools and a little effort, your epoxy floors will look like new again in no time.

Why Should You Fix Yellow Epoxy Floors?

If you have yellow epoxy floors in your home or business, it’s time to take action and fix them. Yellow floors can leave a bad impression on visitors, giving off the impression of a dirty and neglected space.

Not only that, but yellowing can also indicate UV damage or chemical breakdown of the material – both of which can lead to structural issues down the line. Don’t wait until your floors start cracking or peeling before taking action.

By fixing your yellow epoxy floors, you improve your space’s aesthetics and ensure the long-term durability of your flooring. So why wait? Take the necessary steps to keep your floors looking new and maintain your home or business’s professional appearance.

A Step-by-Step Guide on How to Fix Yellow Epoxy Floors

Step 1: Identify the Cause of Yellowing

The first step in restoring the shine of your epoxy floor is to identify the cause of the yellowing. Yellowing can sometimes arise due to exposure to UV rays, oxidation, or the improper mixing of chemicals during installation. If this is the cause, then you need to take precautions to prevent or address these issues before attempting to fix the yellowed floor.

Step 2: Clean the Epoxy Floor

Proper cleaning of the epoxy floor is crucial in restoring its shine. Start by clearing dust and debris off the floor using a broom or vacuum. Next, thoroughly wipe the floor thoroughly with a pH-neutral cleaner and a microfiber mop. Rinse the floor using a squeegee and clean water to remove any cleaner residue.

Step 3: Use a Floor Buffer or Polisher

If cleaning does not fix the yellowing, then you can use a floor buffer or polisher to restore it. You must ensure that the polishing pad you use is compatible with epoxy floors to avoid scratching.

Start by testing the polishing pad in a small, less noticeable area first, and if the result is good, move on to the rest of the floor. Buff the floor in an even pattern, using slow and controlled movements. Ensure that there is equal and consistent pressure on the pad. Perform this process in sections to complete the entire floor.

Step 4: Prime and Paint

If the above steps do not work, you can prime and paint the epoxy floor. Prime the floor to provide a suitable surface for the paint. You can use water-based or solvent-based paint depending on the space environment you want to restore. The paint application process is similar to that of the primer.

Apply the paint on the epoxy floor using a short nap roller. Let the paint dry for a day or two, depending on the humidity and temperature in the space. Apply a second coating if necessary. This method will not only fix the yellowing but also give your epoxy floor a new look.

Step 5: Apply a New Layer of Epoxy

If the above methods do not work, then it’s time to apply a new layer of epoxy on top of the existing one. Mix the epoxy according to the manufacturer’s instructions and spread it evenly over the floor using a squeegee or a trowel. Allow the epoxy to cure for at least 24 hours before walking on it.

Step 6: Add a UV Resistant Topcoat

To prevent yellowing in the future, consider adding a UV-resistant topcoat to your epoxy floor. This will help protect the floor from harmful UV rays and extend its lifespan. Be sure to choose a topcoat that is compatible with epoxy floors.

Step 7: Implement Preventative Measures

To avoid yellowing in the future, there are some preventative measures you can take. These include using UV-resistant coatings, regularly cleaning and maintaining your floor, and avoiding exposure to harsh chemicals or substances. By proactively caring for your epoxy floor, you can prevent yellowing and keep it looking shiny and new for years to come.

5 Considerations Things When You Need to Fix Yellow Epoxy Floors

1. Cause of Yellowing

The first consideration when fixing yellow epoxy floors is to determine the cause of the discoloration. There are multiple reasons why epoxy floors may turn yellow, such as exposure to UV light, chemical reactions, or improper mixing during installation. Identifying the root cause will help determine the best action to fix the issue.

2. Type of Epoxy

It’s important to consider the type of epoxy used on your floors before attempting to fix any yellowing. Some epoxies may be more prone to yellowing than others, and certain types may require different repair methods. It’s best to consult with a professional or refer to manufacturer guidelines for specific recommendations based on the type of epoxy used.

3. Cleaning and Prep Work

Before attempting any repairs, it’s crucial to thoroughly clean and prep the affected area. This includes removing any dirt or debris from the surface and ensuring it is completely dry before proceeding with repairs. Proper cleaning and prep work will ensure that any fixes are effective and long-lasting.

4. Repair Method

Solvents to More Extensive Sanding

There are various methods for fixing yellow epoxy floors, depending on the cause and severity of the discoloration. These can range from simple spot treatments with specialized cleaners or solvents to more extensive sanding and reapplication of a new topcoat. Again, consulting with a professional or following manufacturer guidelines is recommended for the best results.

5. Prevention Measures

Once you have successfully fixed your yellow epoxy floors, taking preventative measures is important to avoid future discoloration issues. This can include using UV-resistant topcoats, avoiding harsh chemicals or cleaning products, and properly maintaining your floors by regularly cleaning and sealing them as needed. Taking these precautions will help keep your epoxy floors looking pristine for years to come.

3 Benefits of Fix Yellow Epoxy Floors

1. Durability and Longevity

One of the primary benefits of epoxy floors is their durability and longevity. Epoxy is a strong and durable material that can withstand heavy foot traffic, machinery, and other wear and tear without showing signs of damage. This makes it an ideal flooring option for high-traffic areas such as warehouses, factories, and garages. Additionally, epoxy floors have a long lifespan, with proper maintenance they can last for up to 20 years.

2. Easy Maintenance

Epoxy floors are also very easy to maintain compared to other flooring options. The smooth surface of epoxy makes it resistant to stains, spills, and chemicals, making it easy to clean up any messes or spills. Regular sweeping and occasional mopping are all needed to keep your epoxy floor looking clean and shiny. This saves time and reduces the need for costly cleaning products.

3. Customizable Design Options

Another benefit of epoxy floors is the ability to customize them to fit your specific needs and preferences. Epoxy comes in various colors, patterns, and finishes, allowing you to create a unique look for your space. You can even add decorative elements like flakes or metallic pigments to give your floor a one-of-a-kind appearance. This makes epoxy floors not only functional but also aesthetically pleasing.

4 Common Mistakes People Make When Trying to Fix Yellow Epoxy Floors

1. Using the Wrong Cleaning Products

Using Harsh Chemicals

One of the most common mistakes people make when trying to fix yellow epoxy floors is using the wrong cleaning products. Epoxy floors are typically sealed with a clear topcoat, and using harsh chemicals or abrasive cleaners can damage this sealant and cause discoloration. Using gentle, non-abrasive cleaners specifically designed for epoxy floors is important.

2. Not Properly Preparing the Surface

Another mistake people make is not properly preparing the surface before attempting to fix yellow epoxy floors. This can include not cleaning the floor thoroughly or not removing any existing coatings or sealants. Properly preparing the surface ensures that any repairs or touch-ups will adhere properly and result in a more even finish.

3. Applying Too Much Pressure When Scrubbing

When trying to remove stains or discoloration from epoxy floors, many people make the mistake of applying too much pressure when scrubbing. This can actually push the stain deeper into the floor and cause further damage. It is important to use a gentle touch when scrubbing and to let any cleaning products sit on the surface for a few minutes before wiping them away.

4. Not Using Protective Gear

Such as Gloves

Epoxy floor repair often involves working with strong chemicals and solvents, which can be harmful if they come into contact with skin or eyes. One common mistake people make is not wearing protective gear such as gloves, goggles, and a mask when working with these substances. It is important to follow safety precautions to protect yourself while fixing yellow epoxy floors.


In conclusion, yellow epoxy floors can be unattractive, but you must not endure them. Applying some of these tips can restore the shine of your epoxy floor and liven up your space again. Ensure you identify the cause of yellowing first and clean the floor before polishing, priming, and painting the floor where necessary. Maintaining your newly restored epoxy floors will keep them looking good for years to come. Thanks for reading our post about how to fix yellow epoxy floors.
