Prime and Paint (Implied)

What happens here

After the final sanding and dust removal, apply a coat of drywall primer over the entire repaired area. Primer helps to seal the porous joint compound, prevent flashing (where the new paint looks different over the patch), and ensure consistent paint absorption. Once the primer is dry, paint the repaired area and surrounding wall with paint that matches the existing wall color. It's often best to paint the entire wall corner to corner or an entire section to ensure an invisible repair.

Goal: Once the patched area is perfectly smooth and blended, prime it to seal the compound and ensure uniform paint adhesion, then paint to match the existing wall color.
