It’s not unusual to see bubbles rising in a freshly applied epoxy coat. The most common cause of this is called “outgassing.” Outgassing is a natural process that occurs when trapped air or gasses from the concrete are released and creates blisters, craters, bubbles, or pinholes in epoxy floors.
How do you get rid of bubbles in epoxy?

How do you stop air bubbles in epoxy?
To help prevent air bubbles from releasing into your resin, pre-seal natural materials such as wood and paper with a brush on or spray sealant prior to resining. Sealing creates a barrier and prevents trapped air from releasing and creating bubbles in the resin.
Why do I have air bubbles in my epoxy?
A Gassy Issue When the temperature is rising in an epoxied substrate before the epoxy cures, these gasses rise to the surface and are trapped by the epoxy’s surface tension. Fortunately, this is easy to avoid. Heat the surface of the bare wood and apply epoxy as the wood cools.How do you stop air bubbles in resin?
A small amount of baby powder can work to reduce bubbles in resin. If you are using colored resin, you can even choose a powder that matches the color of the resin you are using. Use a delicate paintbrush to dust in the powder, then tap out any extra before pouring.
How long does epoxy bubbles take?
3-5 minutes, depending on the resin. This allows the resin to begin de-gassing (popping on it’s own). Do remember that this does cut into the pot time (the working time you have before the resin hardens too much to work with).
