Why am I getting bubbles in my epoxy?
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 long do you have to get bubbles out of epoxy?
#4 – Wait for 5 minutes after you’ve completed mixing the resin and hardener together. 3-5 minutes, depending on the resin. This allows the resin to begin de-gassing (popping on it’s own).
