Take 1/4 cup of cold water and mixed in a 1/4 cup of cornstarch. Then we added a **small** amount of food coloring to give it a little bit of color.
*(Do not add a lot of food coloring…after washing the green paint off the sidewalk, I noticed it left a very light stain behind…so use food coloring at your own risk)!
The paints looked really great when they dried. The cornstarch shows up and the paint has a look to it. We will definitely be doing this again. I also would not recommend using the foam brushes like we did. Next time we will use the cheap . The foam brushes were getting pretty ripped up from the rough surface of the cement.
