There are a few things that can cause your smooth paint to become lumpy. Luckily, there’s also a way to fix it. Acrylic paint becomes chunky when it’s been exposed to too much air. The chunks are actually sections of the paint that have started to dry.
Then, how do you get lumps out of paint?
Keeping this in consideration, why is my paint going on lumpy?
Latex paint can get lumpy for a number of reasons. On store shelves, it settles in the can, leaving the components to separate a little. In older paints, air exposure may start to dry out the paint, leaving skin or clumps behind. When paint is allowed to freeze and thaw, it can break down and develop chunks.
