Reviving dried-out poster paint is possible, but the success depends on how thoroughly the paint has dried. Completely dried acrylic paints become a plastic polymer and are unrecoverable. However, if the paint is only partially dried, you can often restore its workable consistency.
Methods for Reviving Dried Poster Paint
The most common method involves adding water. Since poster paints are typically water-based, adding small amounts of water and mixing thoroughly can often rehydrate the paint. Hot water is generally recommended, as it works better than cold water.

Step-by-step guide:
- Add a few drops of hot water to the dried paint.
- Stir the mixture vigorously.
- Add more hot water gradually, stirring constantly until you achieve the desired consistency.
- Be patient; it may take some time for the water to fully rehydrate the paint.

Tips for Success:
- Start with small amounts of water: Add water incrementally to prevent making the paint too runny.
- Stir thoroughly: Proper mixing ensures the water evenly rehydrates the pigment.
- Patience is key: It may take time for the paint to fully reabsorb the water.
- Consider the type of paint: The success rate will vary depending on the brand and type of poster paint.
What if the Paint is Completely Dried?
If the poster paint is completely hardened, it's unlikely that rehydration will be successful. In this case, consider purchasing new poster paints.
