Unsightly stains on your ceiling can be embarrassing, but, rest assured, there is an easy fix for this problem. Most ceiling water stains are a result of a leaking roof, so once that problem is fixed, you can go on to address the cosmetic issues that resulted from the water leak.
Instructions
1. Use a diluted solution of chlorine bleach and water to lightly spray the entire ceiling surface. Be sure to wipe the entire ceiling surface clean and dry.
2. Use painter's masking tape to mask the edge of the wall where it meets the ceiling. Use 2-inch-wide tape or two rows of 1-inch-wide tape.
3. Use a high-quality interior/exterior grade of paint primer to seal the surface of the ceiling. Make sure to use a primer that is intended for stain blocking.
4. Use a paint roller with the handle extension attached, and then evenly roll the primer onto the ceiling's surface. The primer will have an opaque appearance and may be partially transparent. The intent of the primer is to seal the surface, not to cover the surface.
5. Allow the primer to dry several hours, and then apply a second coat. Allow this second coat to dry overnight.
6. Apply a finish coat of high-quality flat ceiling paint over the primed surface. With the application of two coats of primer and the use of a high-quality paint, only one coat should be needed, however, two coats will last longer and look better.
