Why is it critical to check the paint’s expiration date?

Checking the paint’s expiration date is crucial because expired paint can lead to poor application and finish quality. As paint ages, its chemical composition can change, which may affect its adhesion, consistency, and color retention. An expired product may separate or clump, making it difficult to apply smoothly. This can result in uneven finishes, increased drying times, or a complete failure to adhere to surfaces, all of which compromise the durability and aesthetic appeal of the paint job. Ensuring that paint is within its usable life helps maintain the integrity of the finished project and can prevent additional costs associated with reapplication or repairs.
