Why should I use a primer if I'm painting over existing paint?

Using primer over old paint might seem like extra work, but it can actually make painting easier and look better in the end. Primer helps seal the previous paint, preventing the new paint from bleeding through and creating an uneven finish. It also provides a consistent surface for the new paint to adhere to, ensuring smooth coverage and preventing uneven color patches.
