The ratio you should utilize is a 4:1 ratio of paint to thinning-agent, adding small amounts and gradually thinning until the desired effect is achieved. You can easily thin paint with water, medium, acetone, turpentine, flow-aid, or paint-thinner. If you’ve begun a project where the paint ended up thick, chunky, clumpy, or simply unusable, you know the frustration of not having the perfect paint consistency. Thinning paint is very simple and can make all the difference in the final result of your project.
