How to Store Paint
•Open cans with care•
It’s important not to bend the lid or rim in order to be properly sealed again. Screwdrivers and butter knives aren’t the best here.
•Keep your lid well clean•
The lid well (the groove between the can’s edge and opening) often gets gunked up with paint, which inevitably dries and prevents the lid from closing properly. To keep the well clean, always wipe the rim after pouring with a damp cloth or your brush.
Do not poke holes in the well for ‘drainage’- they cannot be put into shakers again to be mixed.
•Air is the enemy•
When it comes to storing paint, it is important to prevent air from seeping into the can. The fuller the can, the less the air can get in. Therefore, consider decanting smaller quantities of paint (for touch-ups down the road) into smaller cans.
•Keep it cool•
Paint must be stored in a cool (not cold), dry place. Keep cans up off the floors (especially concrete ones) and in boxes to prevent rust. Avoid garages.
•The point of no return•
Once paint is frozen, it is impossible to mix it again. It separates and crystallizes so the integrity of the paint is lost.
