Confirm the source is fixed
Roof leaks, plumbing leaks, condensation and other moisture sources should be resolved before cosmetic work begins.
Inspect the substrate
Soft drywall, sagging material, active moisture or mold-like growth may require remediation or replacement rather than simple stain blocking.
Prime before finish paint
Once the surface is dry and stable, a suitable stain-blocking primer may be needed to prevent discoloration from bleeding through.
