How to Paint a Bathroom: Moisture, Mold & the Right Finish

Key Takeaways

  • Moisture and ventilation should guide the prep, primer, paint, and sheen you choose.
  • Use a bathroom-rated coating in full baths. Choose the sheen by product performance and exposure, not a universal semi-gloss rule.
  • Never paint over active mildew. Clean it, dry the surface, and correct the moisture source before coating
  • Treat the ceiling as a separate surface. A bath-rated matte or moisture-resistant finish can work better than generic flat ceiling paint.
  • Protect the early cure. Follow the product label before showering, keep air moving, and allow extra time in cool or humid conditions.
