Step by step

1. Identify what is worth keeping

Read the original tin to confirm the product type, colour and finish before opening it. Keep only paint you can identify in a container that is not leaking or badly rusted. Note where you used it and whether you realistically need it for a touch-up. Do not mix unknown leftovers to save space; a different sheen or product can dry differently even when the wet colour looks similar.

2. Clean the rim and close the matching lid

Work on a protected surface and wipe wet paint from the rim with an old cloth, following the product’s handling advice. Remove debris that would stop the matching lid seating evenly. Close it as the container instructions specify, using gentle, even pressure rather than denting one side. A damaged rim lets air in and can turn useful paint into a dried skin or a leaking container.

3. Add project details without hiding the original label

Write the room or surface, colour name and code, finish, product name and the date on an extra label. Keep the manufacturer’s safety and product information readable, and record the same details in a notebook or a photo for backup. Clear identification is more useful than a dab of dried colour alone: two similar-looking whites can have different finishes and show up differently on the wall.

4. Store upright in a suitable secure place

Choose a dry, secure place within the temperature range on the tin, away from direct sun and sources of heat. Keep the sealed container upright where it cannot be knocked over, and separate it from food and household drinking containers. Before a later touch-up, check the paint and test on a discreet area. Ask your local waste service about unwanted paint; disposal rules differ by country and locality.

Final checks

The lid is properly seated, the original label remains readable and the storage place meets the tin’s instructions. Do not assume an old tin is usable just because it has been sealed.
