What can you use to protect satin enamel paint?

To protect satin enamel paint, you can apply a clear polyurethane or a water-based clear coat designed for use over latex paints. These products provide a durable layer that enhances the paint's durability and resistance to scratches, stains, and moisture. Ensure the paint is fully cured before applying the protective coat for the best results. Additionally, using a soft cloth for cleaning will help maintain the finish.
