Do I Have to Strain Paint After Thinning?
Ideally, straining paint after thinning helps to check for its consistency and viscosity. If the paint is thin, you can add 1⁄8 cup of paint or more to the mixture and stir well. But if the paint is too thick, you can add 1⁄8 cup of thinning material or more, depending on how thick the paint is, and stir well.
