Save for later: So durable are wall colors!

When it comes to storing paint scraps or putting back a bucket of wall paint for later touch-up work, the question of durability quickly comes into play. Just as for food, one important rule is: Opened containers shorten the life of a paint, while tightly sealed buckets or cans effectively preserve the contents. But how long does a wall paint last?

Wall paints last in unopened containers for so long

As a rule, a best-before date is attached to each container, which provides reliable information on minimum durability. However, this only applies as long as the lid was not opened!

Most unopened, regular wall paints last for about two years, according to the manufacturer, but even then they are mostly still usable. These are, as the name implies, a minimum shelf life that is not so rarely exceeded by three to eight years.

How do I know that the shelf life has expired?

With open vessels, the shelf life is shortened accordingly, it can have expired after one year, or reduce from the original eight to five years. But how does the layman recognize that a paint is spoiled?

In any case, yellowish accumulations on the surface do not yet indicate that the shelf life has been exceeded. Rather, these are mostly binders that have settled up and is easy to stir again.

Sometimes clear liquids or pigments settle up, in any case you should try out whether you can remix the separated phases. Really corrupted colors can be recognized by the following features:

  • The wall paint emits bad smells.
  • They discover recognizable mold growth.
  • The individual components can no longer be mixed.
  • Dried paint residues or dirt are in the paint.
  • The wall paint has thickened over time and can no longer be stirred.

To extend the durability of your wall paint

Always store your wall paint in such a way that it lasts as long as possible! When the containers have opened, close the lid as tight as possible and pull a bag over it for safety.

The storage location is a cool, but frost-free place with as constant as possible temperatures. Ideal would be a cellar room or a cool pantry.

Tips & Tricks

If there is only a comparatively small amount of wall paint in a large bucket, it is best to fill it with screwed jars. If you then store the vessels upside down, ensure a long shelf life!
