Removing a Light Water Stain From Drywall on the Ceiling
A coat of paint fixes most minor water stains on drywall.
When water stains mar your ceiling, the water comes from above. Whether from the roof or a slow leak from a water pipe, the drip itself is more of a problem than the stain. If possible, examine the back of the drywall for mold and treat any you find with a bleach solution. Next, you should address the source of the water that caused the stain. After resolving those issues, removing the stain isn’t difficult once the drywall has had a chance to dry fully.
Mix a solution of equal parts chlorine bleach and water in a bucket. Put on rubber gloves, climb a stepladder and use a sponge to wash the stain thoroughly. The bleach may remove the stain, but even if it doesn’t, it will kill any mold.
Let the drywall dry, then brush on a coat of stain-blocking oil- or water-based primer. Cover an area slightly larger than the stain itself.
Paint the area with the ceiling color after the primer dries. If you haven’t painted the ceiling for a while, the repair may appear lighter than the rest of the ceiling. If so, it’s a good idea to either clean the entire ceiling with detergent and water or paint it.
Things You Will Need
- Chlorine bleach
- Rubber gloves
- Stain-blocking primer
- A persistent leak can wear a hole through the back of the drywall before the damage appears on the front. If the area inside the stain feels spongy and waterlogged, cut out the damaged section with a utility knife and patch the area with new drywall. Repaint after taping and finishing the patch.
- Discolored drywall is often your first indication of a leak that can cause damage that is more serious if you don’t fix it.
