Why stains bleed through paint
Smoke residue is oily and colored. Standard paint is water-based and does not block it. A stain-blocking primer seals the residue so the new paint stays clean.
Steps
- Remove loose soot with HEPA vacuuming and dry sponges.
- Clean with a degreaser suited to the surface.
- Rinse and let dry.
- Apply a stain-blocking primer, often shellac-based or oil-based.
- Repaint with a finish coat.

| Ceiling texture | Cleaning may damage texture; sealing or replacement may be needed |
| Brick and masonry | Specialized cleaners; porous surfaces hold stain |
| Wallpaper | Usually replaced |
