Why You Should Think Twice Before Storing Paint In The Garage
By JUSTO ALVAREZ
Paint is formulated to work
in stable conditions, so a garage's extreme hot and cold temperature fluctuations make it the worst place
to store paint cans.
These extreme temperatures put at risk the stability of the paint formula, potentially making the paint separate, curdle, dry out,
or rot inside the can.
Whether the paint can is brand-new and sealed or has been opened, if the can rusts due to excessive moisture in the air, the paint inside will also be compromised.
Paint cans are best stored in a place that's always cool, dry, and preferably away from the sun. Indoor closets or basements are great long-term storage options.
