Paint storage and touch-up supplies

Short answer: Store leftover paint in a sealed container, labeled with color, sheen, date and room, at room temperature. Keep a small amount in a smaller jar for quick touch-ups.

The worst moment to discover a problem is when you need a touch-up and the paint is dried, separated or unlabeled. A few cheap supplies make leftover paint usable for years.

Do not store paint where it can freeze or overheat. Keep cans off concrete floors if you can and away from heat sources. Wipe the rim before closing the lid so the can seals well, and tap the lid down evenly. For testing colors before you commit, see our sample kit page.

Containers and labels

Who it is for: anyone keeping leftover paint.

Smaller containers reduce the air inside, which helps paint last longer.

Opening, pouring and closing cans

Who it is for: anyone who has dented a can lid.

Proper tools protect the rim so the lid seals.

Preserving paint

Who it is for: paint you want to keep for a while.

Some people use a preserver spray; always read the manufacturer instructions.

Touch-up applicators

Who it is for: small repairs without dragging out a full kit.

Small rollers and brushes avoid flashing, where touched-up areas look different.

FAQ

How do I make touch-ups blend in?
Clean the area, use the same paint and sheen, and feather the edges with a small roller. Touch up the whole wall section if the match is imperfect.
How long does leftover paint keep?
Sealed, at room temperature, it can last a year or longer. Check for sour smell, lumps or separation before using it.
Should I label the paint can?
Yes. Note the color name, sheen, date and room, and keep a swatch on the lid.
Can paint freeze?
Latex paint can be damaged by freezing. Store it where temperatures stay moderate.
