When using Chalk Paint® by Annie Sloan and mixing water with the paint to thin it slightly and get a smoother finish – we recommend pouring out some of the Chalk Paint® into a separate container and then mixing water with it directly. Then, throughout your project, make sure to remix it to keep all the pigments incorporated because it can start to separate a bit. This is especially important with darker colors like Napoleonic Blue, Athenian Black, Amsterdam Green, Graphite.
What you should NOT do…..is just dip your brush into water and then into the paint or use a spray bottle- it can cause the end result to look streaky. Below is an example of what can happen.
Another suggestion is when painting, to paint the whole surface and not going back and feathering specific spots here or there. This is especially important when adding water to your paint.
