Terms of the Trade: What Is the "Boxing" Paint Technique?

A can of white paint and a brush with paint on the edge.

"Boxing" paint is a method used to ensure color consistency between multiple cans of paint. This technique is especially important when a color discrepancy between cans may be apparent over large surface areas. To ensure consistency, pour all cans being used into a large container, such as a 5-gallon bucket, and stir to combine. Once everything is mixed well, the paint can be poured back into the original containers and used.
