See our top tips below for storing surplus paint, and if you don’t think you’ll reuse your paint again, prevent it from going to waste by donating it to Community RePaint, where it will be redistributed for reuse within your local community. Click here to find out more.
1. Replace the lid firmly
To reseal your paint container, tap (using a rubber mallet)/press down the edges of the lid, all the way around the container, to form as tight a seal as possible. This will help to prevent air from getting in and drying out the paint. Placing a layer of clingfilm over the top of the paint before replacing the lid can also help form a stronger seal.
2. Store in a dry place
This will help prevent metal tins from rusting and discolouring your paint.
3. Avoid extreme temperatures
If the temperature drops below zero, ice crystals can form in your paint. When these ice crystals thaw, they cause the paint to separate. This reduces the quality and changes the consistency of the paint – making it unusable (see photos below). Try to avoid storing paint in places, such as your shed or garage, where the temperature will likely fall below 0°C.
If not possible, try to insulate your paint by wrapping the containers with dustsheets or placing them in a box packed with scrunched up newspaper.

4. Donate your paint to Community RePaint
If you don’t think you’re going to reuse your leftover paint again, or don’t have a suitable space to store your paint, donate it instead to Community RePaint. Your paint will then be redistributed for reuse by individuals, families and community groups within your local area.
