Epoxy is one of the best coatings to use on your residential and commercial floors. The coating makes concrete floors strong, durable, and easy to maintain. Besides, it adds some anesthetics to your floor giving it great looks.
However, as time goes by, you’ll notice some chippings and peelings on your epoxy floors. This is usually a result of improper installation and excessive humidity among other causes. The damage could be small or big. For small epoxy floor damages, you can easily patch the floor to prevent extension of the damage.
Here is how it’s done!

1.   How to fix bubbles in epoxy floors

A 60 grit sandpaper and a palm sander are all you need to fix bubbles on your epoxy floor. However, larger bubbles may require a floor buffer.
Once you have identified the damaged area, place the sander on top of that area for about 15 minutes. This procedure helps to scratch up the bubbles leaving room for the application of a new epoxy coat.
Once the area has been sanded, clean it up using a vacuum and a clean cloth. This helps prevent the dust and debris from getting trapped in the epoxy. Also, when wiping up the sanded area, make sure you use a solvent to prevent the bubbles from re-emerging once the area has been patched. When you are done preparing the damaged area of your epoxy floor, give it some time to dry.
As soon as the place is dry, you can now begin recoating with epoxy. You can choose to recoat the entire floor or focus on the damaged part, it all depends on the extent of the damage/bubbles.
When applying the epoxy coating, use a roller and apply it in thin even layers. Once you are done, give it 24 hours to dry.

2.   Remedying discoloration of an epoxy floor

Epoxy discoloration can easily be fixed, especially if the problem affects a small section of your floor. Here, you will need a sealer and a roller.  Premixed sealers are available in almost all home supply stores.
There are two types of sealers for epoxy flooring; liquid pigment sealer and solvent-based tinted sealer.
If your floor was coated with a water-based epoxy, then you should use a liquid pigment sealer to patch up the damaged part. If the epoxy coat was solvent-based, then a solvent-based tinted sealer will be appropriate to patch up the damaged area.
If you wish to darken light patches, you can simply use a dye or a water-based stain. After you have applied the stain or sealer, you should let it dry for up to 10 hours after which, you can add another if necessary.
However, if the stain or sealer doesn’t fix the discoloration on your epoxy floor, you should seek professional help from experts like JDL Surface Innovations. The contractor will help you address the discoloration problems and also offer more suggestions on how to prevent the occurrence of such a problem.

3.   Patching a peeling epoxy floor

If the concrete below the epoxy coating is not prepared properly, then the floor is likely to peel off. To repair the damage, start by scraping away the peeling epoxy using a paint scraper.
After that, use a palm sander to sand the concrete surface. Remember the root of this problem is inadequate preparation of the concrete surface. For healthy reasons, make sure you wear safety glasses, a face mask, and ear protection when using a sander.
Thereafter, use a shop vac to vacuum the surface and remove any dust and debris on the concrete. Use a clean and saturated rag to wipe down the floor and prepare the floor for the coating. Mix your epoxy and apply it again on your concrete floor. Once all the peeling spots have been patched, avoid using the floor for about 24 hours.
