Paint Storage Tip: Gravity Is Your Friend

July 22, 2015

Some fatherly advice I received years ago from dear old Dad was to store my containers of liquid, in particular cans of paint and such, upside down. The demon of air will dry out paint, or cause it to get a dry skin layer inside the can as air that penetrates through the lid. However, when the wet liquid presses against the inside of the lid there’s less air to dry it out, and the paint will last longer.

In this photo above you can see a few small plastic jars of some recently made gouache paint turned upside down on their lids. This is how I store them. Sometimes I put labels on the bottom. Behind them is a jar of Golden Acrylic Gesso, a bottle of acrylic medium, and some paint tubes. The bottle of medium is a little unwieldy on its cap, so I have to place it in a drawer in such a way that it won’t tip over, usually against other similar bottles stored in the same way. The paint tubes can be a problem since most manufacturers use very small caps that won’t let you balance the tube upright. Liquitex tubes are nice and large for that, but not most other brands. Alternatively, you should squeeze the tubes from the end, forcing the paint to the top and get the same benefit.

This is also a good way to store any cans of left over house paint you might have in the garage. Be careful of potential leaks, however, and put a plastic sheet underneath, just in case.

The motivation for this post was my reading that Golden is going to start labeling their cans upside down to encourage people to get use to this way of storing their supplies. Good for them.

  1. Bless your heart, David, many thanks!


  2. […] I’m interrupting my series of posts on the new painting to point out a problem I discovered today with a jar of Casein Gesso from Sinopia. This follows up on two posts I made in the past: one is a review of this product, and another was how I store paint containers like this upside down. […]
