Eggshell Paint Touch-Ups: Will the Sheen Match?

No. Touching up eggshell paint will not result in the same sheen. Eggshell paint has a slightly reflective sheen, which is created by the small particles of eggshells that are added to the paint. When you touch up eggshell paint, you are essentially adding a new layer of paint that does not contain these particles. This will result in a slightly different sheen than the original eggshell paint.

In order to achieve the same sheen when touching up eggshell paint, you should use a paint that is specifically designed for this purpose. These paints contain the same small particles of eggshells that are found in eggshell paint, and they will therefore produce the same sheen when applied.
