It's possible that you may have allowed your paint to sit for an extended period of time before beginning your project. Unfortunately, even with an airtight seal, paint can become dry over time. We recommend attempting to restore the paint's consistency by carefully adding a few drops of lukewarm water and thoroughly mixing it. If the paint does not reach the desired consistency on the first attempt, please don't hesitate to try again. We're confident this solution will help you achieve the perfect finish for your project.
