#8: Wall Paint
After painting our house, it’s common for many of us to stash the remaining paint for future touch-ups. But the reality is that paint doesn’t last forever. Oil-based varieties bid goodbye to their prime after two years, turning either into unusable, hardened blobs or separating into a mess. If you’re committed to a color long-term, consider investing in an extra, unopened can instead to avoid future headaches.

But remember that even the unbroken sanctity of an unopened paint can isn’t eternal. Fresh cans also boast a limited lifespan, expiring after a few years. This makes selecting a paint color more strategic; opting for durable, consistently produced shades could save you from future touch-up trials, ensuring your walls remain pristine longer.
