This damaged ceiling requires some drywall replacement as well as and repainting.
Disasters happen in everyone's lives. Happily some are relatively easy to repair. For example, a tiny roof leak can cause a huge water stain on the ceiling. While it looks terrible, with proper preparation, primer and a fresh coat of paint, no one will ever know about the stain. A homeowner can complete this project in one weekend.
Instructions
1. Mix Trisodium Phosphate (TSP) with warm water according to the package instructions. Using a sponge, wash the stained surfaces with the TSP solution. Rinse with clean water and dry with rags. Allow to dry completely.
2. Sand with fine-grit sandpaper if necessary to smooth the surface of the ceiling or wall. Using painter's tape, mask the areas where you do not want to paint. Use a dropcloth on the floor or carpet to prevent spatters from damaging the surfaces.
3. Roll one coat of primer over the stain, using a stain blocking paint such as Kiltz or Zinsser. Allow to dry completely, then apply a second coat of primer.
4. Roll a coat of matching paint over the primer. Allow to dry, then repeat. Use a dry paintbrush to feather the edges of the repair, blending the new paint with the original. If you don't know what the original paint color was, repaint the entire wall or ceiling in a similar or contrasting color.
