How To Store Leftover Paint

Opening a tin with a screwdriver or sharp tool can dent the air tight seal once your project is complete, allowing paint to spoil and dry. Opt to use a specialist paint can opener and gently reseal the tin with a rubber mallet for a snug close. You can also try covering the opening with cling film before securing the lid to ensure any dust or dirt doesn’t enter on re-opening.

Clean down larger tins before storing to avoid dry paint flakes falling into the tin. For small left-over amounts, transfer to clean and dry recycled jars or tins. Seal tightly and store in a dark place, for a quick check on colours and quantities before you start the next project. Just make sure to keep out of the way of children and pets.

Label the tins with duct tape or masking tape and mark the brand, colour, finish and where it was used, for easy touching up of scuffs and scrapes at a glance. For larger tins, use your paint brush to swatch a small colour sample on the lid and side, for easy identification later on.

Paint can dry up and split with extreme temperature changes so the shed or garage may not always be the best for storage. Instead opt for under the stairs, a utility room cupboard or the garage, moving them as necessary throughout the year.

Stored paint will need to be mixed thoroughly before use to ensure any separated ingredients combine for an identical colour match. Making sure no dust or debris has fallen in from opening the lid, use a wooden stick or mixer attached to a power drill to combine well.
