Immediate Storage Tips
Seal Pots Tightly
The #1 rule: close your paint pots securely after every painting session. Acrylic paint dries out when exposed to air. A properly sealed pot keeps paint usable for 6-12 months. Make sure the lid clicks or snaps firmly — no gaps.
Clean the Rim Before Sealing
Dried paint around the rim prevents a tight seal. Wipe the rim with a damp paper towel before closing. This ensures an airtight seal every time.
Store Upside Down
An old artist's trick: store paint pots upside down. The paint itself creates an airtight seal against the lid, preventing air from drying out the contents. This can double the shelf life of your paint.

Long-Term Storage
- Room temperature — avoid extreme heat or cold. Do not store near windows, heaters, or in freezing garages
- Away from direct sunlight — UV light degrades paint pigments over time
- In a sealed container — put all pots in a ziplock bag or airtight box for extra protection
- Label the kit name — so you know which painting the colors match
Reviving Dried Paint
If paint has thickened but is not completely solid:
- Add 1-2 drops of water
- Stir with a toothpick for 30 seconds
- Wait 5 minutes and stir again
- The paint should return to a creamy consistency
If paint has completely dried into a solid chunk, unfortunately it cannot be revived. This is why proper storage is so important.
