Leaky toilets, bathtubs and sinks on upper levels often time result in water damaged ceilings that sag. As long as the drywall is completely dry and mold free, repairing saggy ceilings is a non-invasive process. A professional should repair ceilings with extensive water damage and mold.
Instructions
1. Protect surrounding surfaces and floors with a large tarp or plastic to keep them free of dust, putty and paint.
2. Remove paint and texturing from the ceiling by sanding the damaged section with a mesh sander.
3. Reattach the sagging ceiling to the floor joists by pushing up on the drywall and nailing it in place. Follow the seam to reattach the drywall.
4. Paint the ceiling with and oil based primer to prevent the water stains from coming through the newly repaired and painted area. Let the primer dry completely before moving on.
5. Make a thin mixture of drywall compound. Roll the compound onto the repaired portion of the ceiling with a paint roller.
6. Texture the ceiling to blend with the surrounding areas by using a stomping brush. Create the ceiling texture while the drywall compound is still moist but not wet.
7. Cover over the repaired surface with a ceiling paint that matches the rest of the ceiling. Paint the entire ceiling when the old paint is dingy and will not match up to a new paint color.
