No one likes dried up paint and our Chalk Paste is the same way. Unlike most paints, you can save your paste by adding water! There are times this amazing product gets thirsty! So don’t forget to add water (distilled is recommended to keep bacteria out) and stir, stir, stir! It should be the consistency of Yogurt or Cake Batter. If you paste ever arrives hard to stir, please reach out to me at email@example.com so I can get it replaced for you.
