Ultra-washable paint:
50% washable tempera paint
50% dish soap or bubble bath or old shampoo that you have left over after switching brands
That’s it. Mix those two together.
It will create an extremely washable paint. Because of the soap, it is also very runny. This is a good activity for toddlers or young children for whom painting is about the process, not creating an end result. This doesn’t create a very sophisticated end result.
What can you use ultra-washable paint for?
-Painting on the walls of the shower or bathtub
-Painting on the outside of glass, like a car window or sliding glass door
-Painting on the concrete, sidewalk, driveway, or deck
-Painting on the fence, outdoor wall, garage, or other vertical surface
Because it’s already half soap by volume, ultra-washable paint washes away pretty easily if sprayed with a hose or shower head. It’s loads of fun for pour-painting, splatter-painting, mixing in with potions, etc, too!
Note that any paint or dye of any kind, no matter how washable, might stain super porous surfaces. So be mindful when using it—use your best judgment.
