After repairing leaks, ensuring the structure is sound and cleaning the wall, homeowners can remove water stains from drywall by sealing the stain with an oil-based primer and touching up the paint job with matching paint. A simple roller or paint brush are all that is required to apply the primer and paint.
Follow these steps belowto seal and remove water stains from a wall or ceiling.
- Repair the leak
- Inspect the area
- Clean the area
Any stain removal efforts will fail without first repairing the leak that caused the water stain in the first place. Repair the leak before trying to remove the stain.
After repairing the leak, inspect the area to ensure the surface was not damaged. Soggy drywall is beyond sealing, so the drywall in this case would need to be cut out and replaced.
Before sealing the stain, prepare the surface by scraping away any loose paint and scrubbing the area with a household cleaner. Kill any mold or mildew with a commercial cleaner or a bleach and water mixture, and thoroughly dry the area before proceeding.
Prime the stain with one or two coats of an oil-based primer. Allow the primer to fully dry before proceeding.
Touch up the area with matching paint, or repaint the whole area to finish the job and repair the water stain.
