Have Bubbles In Your Epoxy Floor? Here’s How To Remove Them

It is not so rare to see bubbles appear on epoxy coating. You can find small bubbles, the size of the pinhead, or some large ones, that have an inch in diameter. You can find them in groups or scaterred around the floor. This is usually due to a phenomenon called ‘out gassing’. This usually happens in the tim epoxy paint is drying up. The rise in temperature is the reason for the heating of the air in the concrete making it expand and form bubbles.

Use application primer as a tool that can help to prevent bubbles. You should use a slower drill to mix the epoxy coating, and when you start to apply it, be sure there is no sunlight hitting directly on the surface you are working with.

Use medium roller if you already decided to use one. You need to take care how you apply the epoxy, make slow, gentle motions. Our epoxy garage paint will have less bubbles with this.

Bubbles that are formed in epoxy floorings can be removed using grit sandpaper and a rotary scrubber. First roughen the bubbled area with the sandpaper. Then get on to some serious dust cleaning work. Then with a rag wipe the surface area with a strong solvent. After this another coating can be applied. Another type of bubble observed is fisheyes. One of the reasons is the silicone that remained on the surface.

Use sandpaper of medium grit to clean this area in entirety. When you are finished with this, you can clean the entire place with solvent dipped rag. And now you are ready to apply fresh epoxy coating.

Consider shot blasting or sand blasting the entire epoxy coating in case the bubbles are spread all over that floor. You will need to sand blast the entire area of epoxy coating first. Afterwards clean the problem area with acid. In case you are working on a very small area, you can isolate it. You will need to repair the area first and the you will have to make a new coating.

Our epoxy floors can have bubbles due to another reason: moisture. To verify this break one of the blisters thus formed and see if there is any moisture inside.
