Likewise, people ask, how do you fix bubbles in paint?

Generally, these bubbles pop quickly, leaving the paint to dry smooth. If you notice the bubbles popping soon after application, they usually go away on their own without leaving craters. If not, adjust your paint, roller or technique to minimize bubbling.
