What Can Cause  Bubbles in Cured Epoxy Floor?

There are a few different things that can cause bubbles to form in cured epoxy floors.

One common cause is when the epoxy mix is not properly mixed before it is applied to the floor. If there are any pockets of air in the epoxy, they will eventually rise to the surface and create bubbles.

Another common cause is when the epoxy is applied in too thick of a layer. This can also trap pockets of air beneath the surface, which will eventually lead to bubbling.

Finally, bubbles can also form if the epoxy is exposed to excessive heat or direct sunlight during the curing process. This can cause the epoxy to cure too quickly, which can again trap pockets of air beneath the surface.

10 Steps on How to Fix Bubbles in Cured Epoxy Floor:

The good news is that there are a few different ways that you can fix bubbles in cured epoxy floors. Follow these steps to remove the bubbles and restore your beautiful, smooth floor.

1. Assessing the Situation:

Start by assessing the situation and determining how many bubbles and large they are. If there are only a few small bubbles, you may be able to fix them with a simple home remedy. However, if there are many large bubbles, you may need to sand down the entire floor and start over. Make sure to take pictures of the floor so you can show them to a professional if necessary.

2. Clean the Floor:

Before you do anything, it’s important to clean the floor. Start by sweeping away any dirt or debris. Then, use a damp mop to remove any remaining dirt or residue. Make sure the floor is completely dry before you proceed to the next step. If the floor is left wet, it could prevent the epoxy from adhering properly.

3. Sand Down the Floor:

If you’re dealing with many large bubbles, you’ll need to sand down the entire floor and start over. Use a palm sander or orbital sander for sanding away the top layer of epoxy. Be sure to wear a dust mask to avoid breathing in the epoxy dust.

4. Apply Heat:

One way to fix small bubbles is to apply heat. Use a hair dryer or heat gun to heat the area with the bubbles carefully. The heat will cause the epoxy to expand, which should pop the bubble and smooth out the surface. Be careful not to overheat the epoxy, as this can cause other problems.

5. Apply a New Layer of Epoxy:

Once the floor is sanded down, you’ll need to apply a new layer of epoxy. Be sure to mix the epoxy thoroughly before applying it to the floor. Use a roller or brush to apply an even layer of epoxy over the entire surface. If necessary, you can use a heat gun to gently heat the epoxy as it’s drying to help prevent bubbles from forming.

6. Let the Epoxy Dry:

Once the new layer of epoxy is applied, let it dry completely. This can take anywhere from 24 to 48 hours. Do not walk on the floor during this time, as it could cause imperfections.

7. Apply the Second Layer of Epoxy:

After the first layer of epoxy has dried, you can apply a second layer if desired. This will help to smooth out the surface further and create a more durable finish. This step is optional, but we recommend it if you’re dealing with many bubbles.

8. Polish the Floor:

Once the epoxy has cured, you can polish the floor to create a shiny, smooth finish. Use a floor polisher or buffer to polish the surface. Start with a lower speed and gradually increase the speed until you’re satisfied with the results.

9. Let the Floor Cure:

Once the final layer of epoxy is applied, let the floor cure for at least 24 hours before walking on it. This will allow the epoxy to harden fully and prevent any further bubbles from forming.

10. Clean Up:

Once you’re finished, be sure to clean up any dust or debris. Sweep and mop the floor to remove any epoxy residue. Be careful not to walk on the floor while it’s still wet. After following these steps should have a beautiful, smooth, bubble-free floor. Enjoy your new epoxy floor, and be proud of your handy work!

And there you have it! These steps should help you fix bubbles in cured epoxy floors. If you have any questions or concerns, be sure to consult a professional.
